81-422: Dennett describes the theory as first-person operationalism . As he states it: The Multiple Drafts model makes [the procedure of] "writing it down" in memory criterial for consciousness: that is what it is for the "given" to be "taken" ... There is no reality of conscious experience independent of the effects of various vehicles of content on subsequent action (and hence, of course, on memory). Dennett's thesis

162-429: A fuzzy concept so as to make it clearly distinguishable, measurable, and understandable by empirical observation . In a broader sense, it defines the extension of a concept —describing what is and is not an instance of that concept. For example, in medicine, the phenomenon of health might be operationalized by one or more indicators like body mass index or tobacco smoking . As another example, in visual processing

243-452: A 2003 study in which participants viewed animated geometric shapes in different "vignettes," some of which could be interpreted as constituting social interaction, while others suggested mechanical behavior. Viewing social interactions elicited activity in brain regions associated with identifying faces and biological objects (posterior temporal cortex), as well as emotion processing (right amygdala and ventromedial prefrontal cortex). Meanwhile,

324-516: A behaviour; it does not have to wait to be presented at the theatre. Like a number of other theories, the Multiple Drafts model understands conscious experience as taking time to occur, such that percepts do not instantaneously arise in the mind in their full richness. The distinction is that Dennett's theory denies any clear and unambiguous boundary separating conscious experiences from all other processing. According to Dennett, consciousness

405-410: A different logic when testing a formal (quantitative) hypothesis and testing working hypothesis (qualitative). For formal hypotheses the concepts are represented empirically (or operationalized) as numeric variables and tested using inferential statistics . Working hypotheses (particularly in the social and administrative sciences), however, are tested through evidence collection and the assessment of

486-599: A double dissociation between the intentional and phenomenal stances. In a follow-up paper, Robbins and Jack describe four experiments about how the intentional and phenomenal stances relate to feelings of moral concern. The first two experiments showed that talking about lobsters as strongly emotional led to a much greater sentiment that lobsters deserved welfare protections than did talking about lobsters as highly intelligent. The third and fourth studies found that perceiving an agent as vulnerable led to greater attributions of phenomenal experience. Also, people who scored higher on

567-412: A larger framework of concepts. When there is a large empirical research question or purpose the conceptual framework that organizes the response to the question must be operationalized before the data collection can begin. If a scholar constructs a questionnaire based on a conceptual framework, they have operationalized the framework. Most serious empirical research should involve operationalization that

648-458: A lot going for it" from the perspective of psychology and neuroscience. They review studies on abilities to adopt an intentional stance (variously called "mindreading", "mentalizing", or "theory of mind") as distinct from adopting a physical stance ("folk physics", "intuitive physics", or "theory of body"). Autism seems to be a deficit in the intentional stance with preservation of the physical stance, while Williams syndrome can involve deficits in

729-420: A mind that has perceptually changing content without a definitive present instant. To those who believe that consciousness entails something more than behaving in all ways conscious, Dennett's view is seen as eliminativist , since it denies the existence of qualia and the possibility of philosophical zombies . However, Dennett is not denying the existence of the mind or of consciousness, only what he considers

810-471: A naive view of them. The point of contention is whether Dennett's own definitions are indeed more accurate: whether what we think of when we speak of perceptions and consciousness can be understood in terms of nothing more than their effect on behaviour. The role of information processing in consciousness has been criticised by John Searle who, in his Chinese room argument, states that he cannot find anything that could be recognised as conscious experience in

891-501: A period of thousands of years. In the 1930s, Harvard experimental psychologist Edwin Boring and students Stanley Smith Stevens and Douglas McGregor , struggling with the methodological and epistemological problems of defining measurement of psychological phenomena, found a solution in reformulating psychological concepts operationally, as it had been proposed in the field of physics by Bridgman, their Harvard colleague. This resulted in

972-457: A physical theory, it may be discovered that what was thought to be one concept is actually two or more distinct concepts. Bridgman proposed that if only operationally defined concepts are used, this will never happen. Bridgman's theory was criticized because "length" is measured in various ways (e.g. it is impossible to use a measuring rod to measure the distance to the Moon), so "length" logically

1053-442: A property that emerges from lots of distributed quasi-understanding in a large system". Operationalism In research design , especially in psychology , social sciences , life sciences and physics , operationalization or operationalisation is a process of defining the measurement of a phenomenon which is not directly measurable , though its existence is inferred from other phenomena. Operationalization thus defines

1134-453: A question, such as "are you angry", or "how angry are you?". This operation is problematic, however, because it depends upon the definition of the individual. Some people might be subjected to a mild annoyance, and become slightly angry, but describe themselves as "extremely angry," whereas others might be subjected to a severe provocation, and become very angry, but describe themselves as "slightly angry." In addition, in many circumstances it

1215-432: A researcher may wish to measure the concept "anger." Its presence, and the depth of the emotion, cannot be directly measured by an outside observer because anger is intangible. Rather, other measures are used by outside observers, such as facial expression, choice of vocabulary, loudness and tone of voice. If a researcher wants to measure the depth of "anger" in various persons, the most direct operation would be to ask them

1296-519: A series of articles that were published by Stevens and McGregor from 1935, that were widely discussed in the field of psychology and led to the Symposium on operationism in 1945, to which Bridgman also contributed. The practical 'operational definition' is generally understood as relating to the theoretical definitions that describe reality through the use of theory . The importance of careful operationalization can perhaps be more clearly seen in

1377-649: A single theoretical concept. Einstein's disagreement with the operationalist approach was criticized by Bridgman as follows: "Einstein did not carry over into his general relativity theory the lessons and insights he himself has taught us in his special theory." (p. 335). Operationalization is often used in the social sciences as part of the scientific method and psychometrics . Particular concerns about operationalization arise in cases that deal with complex concepts and complex stimuli (e.g., business research, software engineering) where unique threats to validity of operationalization are believed to exist. For example,

1458-411: A system that relies solely on motions of things from place to place. Dennett sees this argument as misleading, arguing that consciousness is not to be found in a specific part of the system, but in the actions of the whole. In essence, he denies that consciousness requires something in addition to capacity for behaviour, saying that philosophers such as Searle, "just can't imagine how understanding could be

1539-445: A systematic, "reason-giving explanation" for a particular action, and an account of the historical origins of that action, based on deeply embedded assumptions about the agent; namely that: This approach is also consistent with the earlier work of Fritz Heider and Marianne Simmel , whose joint study revealed that, when subjects were presented with an animated display of 2-dimensional shapes, they were inclined to ascribe intentions to

1620-443: A thought in his head." Dennett has argued against this by denying the premise, on the basis that the robot is a philosophical zombie and therefore metaphysically impossible. In other words, if something acts in all ways conscious, it necessarily is, as consciousness is defined in terms of behavioral capacity, not ineffable qualia . Another objection attacks the premise that treating people as ideally rational creatures will yield

1701-408: A three level system were Allen Newell , Zenon Pylyshyn , and David Marr . The parallels between the four representations (each of which implicitly assumed that computers and human minds displayed each of the three distinct levels) are detailed in the following table: The most obvious objection to Dennett is the intuition that it "matters" to us whether an object has an inner life or not. The claim

1782-447: Is a mysterious doctrine (at least as mysterious as papal infallibility) unless we shift the emphasis a little and treat qualia as logical constructs out of subjects' qualia-judgments: a subject's experience has the quale F if and only if the subject judges his experience to have quale F. We can then treat such judgings as constitutive acts, in effect, bringing the quale into existence by the same sort of license as novelists have to determine

1863-423: Is a special time and place where unconscious processing becomes consciously experienced, entering into what Dennett calls the " Cartesian theatre ". Both theories require us to cleanly divide a sequence of perceptions and reactions into before and after the instant that they reach the seat of consciousness, but he denies that there is any such moment, as it would lead to infinite regress. Instead, he asserts that there

1944-429: Is claimed) somehow does not have any thoughts or feelings at all, just a chip which controls his behaviour; in other words, "the lights are on but no one's home". According to the intentional systems theory (IST), Jones and the robot have precisely the same beliefs and desires, but this is claimed to be false. The IST expert assigns the same mental states to Blockhead as he does to Jones, "whereas in fact [Blockhead] has not

2025-669: Is fundamentally misdirected (see, e.g., Block, 1993, 1995; Shoemaker, 1993; and Tye, 1993). Multiple drafts is also attacked for making a claim to novelty. It may be the case, however, that such attacks mistake which features Dennett is claiming as novel. Korb states that, "I believe that the central thesis will be relatively uncontentious for most cognitive scientists, but that its use as a cleaning solvent for messy puzzles will be viewed less happily in most quarters." ( Korb 1993 ) In this way, Dennett uses uncontroversial ideas towards more controversial ends, leaving him open to claims of unoriginality when uncontroversial parts are focused upon. Even

2106-453: Is impractical to ask subjects whether they are angry. Since one of the measures of anger is loudness, the researcher can operationalize the concept of anger by measuring how loudly the subject speaks compared to his normal tone. However, this must assume that loudness is a uniform measure. Some might respond verbally while others might respond physically. One of the main critics of operationalism in social science argues that "the original goal

2187-427: Is no immediate error, a higher-level stance can simply fail to be useful. If we were to try to understand the thermostat at the level of the intentional stance, ascribing to it beliefs about how hot it is and a desire to keep the temperature just right, we would gain no traction over the problem as compared to staying at the design stance, but we would generate theoretical commitments that expose us to absurdities, such as

2268-406: Is no privileged place in the brain where consciousness happens. Dennett states that, "[t]here does not exist ... a process such as 'recruitment of consciousness' (into what?), nor any place where the 'vehicle's arrival' is recognized (by whom?)" Cartesian materialism is the view that there is a crucial finish line or boundary somewhere in the brain, marking a place where the order of arrival equals

2349-400: Is no screen, hence no reason to re-present data after it has already been analysed. Dennett says that, "the Multiple Drafts model goes on to claim that the brain does not bother 'constructing' any representations that go to the trouble of 'filling in' the blanks. That would be a waste of time and (shall we say?) paint. The judgement is already in so we can get on with other tasks!" According to

2430-421: Is not one concept but many , with some concepts requiring knowledge of geometry . Each concept is to be defined by the measuring operation used. So the criticism is that there are potentially infinite concepts, each defined by the methods that measured it, such as angle of sighting, day of the solar year, angular subtense of the moon, etc. which were gathered together, some astronomical observations taken over

2511-608: Is not one perfect way to operationalize. For example, in the United States the concept distance driven would be operationalized as miles, whereas kilometers would be used in Europe. Operationalization is part of the empirical research process. An example is the empirical research question of if job satisfaction influences job turnover. Both job satisfaction and job turnover need to be measured. The concepts and their relationship are important — operationalization occurs within

2592-436: Is remembered. To put it another way, consciousness is the property of having enough influence to affect what the mouth will say and the hands will do. Which inputs are "edited" into our drafts is not an exogenous act of supervision, but part of the self-organizing functioning of the network, and at the same level as the circuitry that conveys information bottom-up. The conscious self is taken to exist as an abstraction visible at

2673-426: Is that our modern understanding of consciousness is unduly influenced by the ideas of René Descartes . To show why, he starts with a description of the phi illusion . In this experiment, two different coloured lights, with an angular separation of a few degrees at the eye, are flashed in succession. If the interval between the flashes is less than a second or so, the first light that is flashed appears to move across to

2754-408: Is that we don't just imagine the intentional states of other people in order to predict their behaviour; the fact that they have thoughts and feelings just like we do is central to notions such as trust, friendship and love. The Blockhead argument proposes that someone, Jones, has a twin who is in fact not a person but a very sophisticated robot which looks and acts like Jones in every way, but who (it

2835-486: Is that, when understanding, explaining, and/or predicting the behavior of an object, we can choose to view it at varying levels of abstraction. The more concrete the level, the more accurate in principle our predictions are; the more abstract, the greater the computational power we gain by zooming out and skipping over the irrelevant details. Dennett defines three levels of abstraction, attained by adopting one of three entirely different "stances", or intellectual strategies:

2916-429: Is to be deemed pre-experiential or post-experiential. ... [T]hey even agree about how it ought to "feel" to subjects: Subjects should be unable to tell the difference between misbegotten experiences and immediately misremembered experiences. [p. 125, original emphasis.] Dennett argues that there is no principled basis for picking one of these theories over the other, because they share a common error in supposing that there

2997-440: Is to be found in the actions and flows of information from place to place, rather than some singular view containing our experience. There is no central experiencer who confers a durable stamp of approval on any particular draft. Different parts of the neural processing assert more or less control at different times. For something to reach consciousness is akin to becoming famous, in that it must leave behind consequences by which it

3078-550: Is transparent and linked to a conceptual framework. Another example, the hypothesis Job satisfaction reduces job turnover is one way to connect (or frame) two concepts – job satisfaction and job turnover. The process of moving from the idea job satisfaction to the set of questionnaire items that form a job satisfaction scale is operationalization. For example, it is possible to measure job satisfaction using only two simple questions: "All in all, I am satisfied with my job", and, "In general, I like my job." Operationalization uses

3159-407: Is used outside the circumstances for which it was designed. The actions of a mercury thermometer heated to 500 °C can no longer be predicted on the basis of treating it as a thermometer; we have to sink down to the physical stance to understand it as a melted and boiled piece of junk. For that matter, the "actions" of a dead bird are not predictable in terms of beliefs or desires. Even when there

3240-412: Is what we often do when someone is behaving unpredictably — we look for the reasons why. In other words, we can only deal with irrationality by contrasting it against the background assumption of rationality. This development significantly undermines the claims of the intentional stance argument. The rationale behind the intentional stance is based on evolutionary theory, particularly the notion that

3321-740: The "distinguishing characteristic of all mental phenomena" was "the reference to something as an object" – a characteristic he called " intentional inexistence ". Dennett constantly speaks of the " aboutness " of intentionality ; for example: "the aboutness of the pencil marks composing a shopping list is derived from the intentions of the person whose list it is" (Dennett, 1995, p. 240). John Searle (1999, pp. 85) stresses that "competence" in predicting/explaining human behaviour involves being able to both recognize others as " intentional " beings, and interpret others' minds as having "intentional states" (e.g., beliefs and desires): According to Dennett (1987, pp. 48–49), folk psychology provides

3402-425: The ability to make quick predictions of a system's behaviour based on what we think it might be thinking was an evolutionary adaptive advantage. The fact that our predictive powers are not perfect is a further result of the advantages sometimes accrued by acting contrary to expectations. Philip Robbins and Anthony I. Jack suggest that "Dennett's philosophical distinction between the physical and intentional stances has

3483-415: The accuracy of Dennett's characterisations of existing theories: The now standard response to Dennett's project is that he has picked a fight with a straw man . Cartesian materialism, it is alleged, is an impossibly naive account of phenomenal consciousness held by no one currently working in cognitive science or the philosophy of mind. Consequently, whatever the effectiveness of Dennett's demolition job, it

3564-493: The assumptions that: Also, the intentional stance meets the criteria Dennett specified (1995, pp. 50–51) for algorithms: The general notion of a three level system was widespread in the late 1970s/early 1980s; for example, when discussing the mental representation of information from a cognitive psychology perspective, Glass and his colleagues (1979, p. 24) distinguished three important aspects of representation: Other significant cognitive scientists who also advocated

3645-444: The best predictions. Stephen Stich argues that people often have beliefs or desires which are irrational or bizarre, and IST doesn't allow us to say anything about these. If the person's "environmental niche" is examined closely enough, and the possibility of malfunction in their brain (which might affect their reasoning capacities) is looked into, it may be possible to formulate a predictive strategy specific to that person. Indeed this

3726-418: The controversy inherent in this, there is also some dispute about the extent to which Dennett is committing to realism about mental properties. Initially, Dennett's interpretation was seen as leaning more towards instrumentalism , but over the years, as this idea has been used to support more extensive theories of consciousness , it has been taken as being more like Realism. His own words hint at something in

3807-430: The development of General Relativity . Einstein discovered that there were two operational definitions of " mass " being used by scientists: inertial , defined by applying a force and observing the acceleration, from Newton's Second Law of Motion ; and gravitational , defined by putting the object on a scale or balance. Previously, no one had paid any attention to the different operations used because they always produced

3888-638: The empathetic-concern subscale of the Interpersonal Reactivity Index had generally higher absolute attributions of mental experience. Bryce Huebner (2010) performed two experimental philosophy studies to test students' ascriptions of various mental states to humans compared with cyborgs and robots. Experiment 1 showed that while students attributed both beliefs and pains most strongly to humans, they were more willing to attribute beliefs than pains to robots and cyborgs. "[T]hese data seem to confirm that commonsense psychology does draw

3969-400: The evidence. The evidence is generally collected within the context of a case study . The researcher asks if the evidence is sufficient to "support" the working hypothesis. Formal operationalization would specify the kinds of evidence needed to support the hypothesis as well as evidence which would "fail" to support it. Robert Yin recommends developing a case study protocol as a way to specify

4050-426: The final result presented as fully resolved. This is akin to Joseph Stalin 's show trials , where the verdict has been decided in advance and the trial is just a rote presentation. [W]e can suppose, both theorists have exactly the same theory of what happens in your brain; they agree about just where and when in the brain the mistaken content enters the causal pathways; they just disagree about whether that location

4131-481: The hair color of their characters by fiat. We do not ask how Dostoevski knows that Raskolnikov's hair is light brown. In other words, once we've explained a perception fully in terms of how it affects us, there is nothing left to explain. In particular, there is no such thing as a perception which may be considered in and of itself (a quale ). Instead, the subject's honest reports of how things seem to them are inherently authoritative on how things seem to them, but not on

4212-527: The independent existence of what Ned Block has labeled phenomenal consciousness . He argues that "Everything real has properties, and since I don't deny the reality of conscious experience, I grant that conscious experience has properties". Having related all consciousness to properties, he concludes that they cannot be meaningfully distinguished from our judgements about them. He writes: The infallibilist line on qualia treats them as properties of one's experience one cannot in principle misdiscover, and this

4293-405: The initial, quite radical operationalist ideas eventually came to serve as little more than a "reassurance fetish" for mainstream methodological practice." The above discussion links operationalization to measurement of concepts . Many scholars have worked to operationalize concepts like job satisfaction , prejudice, anger etc. Scale and index construction are forms of operationalization. There

4374-449: The internal states created by the two stimuli are identical, hence are so reported. Bogen (1992) points out that the brain is bilaterally symmetrical. That being the case, if Cartesian materialism is true, there might be two Cartesian theatres, so arguments against only one are flawed. Velmans (1992) argues that the phi effect and the cutaneous rabbit illusion demonstrate that there is a delay whilst modelling occurs and that this delay

4455-722: The kinds of evidence needed during the data collection phases. He identifies six sources of evidence: documentation; archival records; interviews ; direct observations; participant observation and physical or cultural artifacts . In the field of public administration, Shields and Tajalli (2006) have identified five kinds of conceptual frameworks ( working hypothesis , descriptive categories, practical ideal type, operations research, and formal hypothesis ). They explain and illustrate how each of these conceptual frameworks can be operationalized. They also show how to make conceptualization and operationalization more concrete by demonstrating how to form conceptual framework tables that are tied to

4536-600: The level of the intentional stance , akin to a body of mass having a "centre of gravity". Analogously, Dennett refers to the self as the "centre of narrative gravity", a story we tell ourselves about our experiences. Consciousness exists, but not independently of behaviour and behavioural disposition, which can be studied through heterophenomenology . The origin of this operationalist approach can be found in Dennett's immediately preceding work. Dennett (1988) explains consciousness in terms of access consciousness alone, denying

4617-586: The light of its beliefs. A little practical reasoning from the chosen set of beliefs and desires will in most instances yield a decision about what the agent ought to do; that is what you predict the agent will do. Dennett (1971, p. 87) states that he took the concept of " intentionality " from the work of the German philosopher Franz Brentano . When clarifying the distinction between mental phenomena (viz., mental activity) and physical phenomena, Brentano (p. 97) argued that, in contrast with physical phenomena,

4698-439: The literature and operationalization tables that lay out the specifics of how to operationalize the conceptual framework (measure the concepts). Intentional stance The intentional stance is a term coined by philosopher Daniel Dennett for the level of abstraction in which we view the behavior of an entity in terms of mental properties . It is part of a theory of mental content proposed by Dennett, which provides

4779-409: The matter of how things actually are. So when we look one last time at our original characterization of qualia, as ineffable, intrinsic, private, directly apprehensible properties of experience, we find that there is nothing to fill the bill. In their place are relatively or practically ineffable public properties we can refer to indirectly via reference to our private property-detectors—private only in

4860-414: The mechanical interactions activated regions related to identifying objects like tools that can be manipulated (posterior temporal lobe). The authors suggest "that these findings reveal putative 'core systems' for social and mechanical understanding that are divisible into constituent parts or elements with distinct processing and storage capabilities." Robbins and Jack argue for an additional stance beyond

4941-477: The middle, as he suggests that the self is as real as a center of gravity, "an abstract object , a theorist's fiction", but operationally valid. As a way of thinking about things, Dennett's intentional stance is entirely consistent with everyday commonsense understanding; and, thus, it meets Eleanor Rosch 's (1978, p. 28) criterion of the "maximum information with the least cognitive effort". Rosch argues that, implicit within any system of categorization, are

5022-410: The model, there are a variety of sensory inputs from a given event and also a variety of interpretations of these inputs. The sensory inputs arrive in the brain and are interpreted at different times, so a given event can give rise to a succession of discriminations, constituting the equivalent of multiple drafts of a story. As soon as each discrimination is accomplished, it becomes available for eliciting

5103-436: The most basic concepts are defined through the operations by which we measure them. The practice originated in the field of physics with the philosophy of science book The Logic of Modern Physics (1927), by Percy Williams Bridgman , whose methodological position is called "operationalism". Bridgman wrote that in the theory of relativity a concept like "duration" can split into multiple different concepts. In refining

5184-406: The multiple drafts model is that, after removing qualia, explaining consciousness boils down to explaining the behaviour we recognise as conscious. Consciousness is as consciousness does. Psychobiologist John Staddon contrasts a simple "new behaviorism" interpretation of color phi with Dennett and Kinsbourne's account. The basic idea is that because of well-known processes such as lateral inhibition,

5265-399: The notion of consciousness as drafts is not unique to Dennett. According to Hankins, Dieter Teichert suggests that Paul Ricoeur 's theories agree with Dennett's on the notion that "the self is basically a narrative entity, and that any attempt to give it a free-floating independent status is misguided." [Hankins] Others see Derrida 's (1982) representationalism as consistent with the notion of

5346-498: The order of "presentation" in experience because what happens there is what you are conscious of. ... Many theorists would insist that they have explicitly rejected such an obviously bad idea. But ... the persuasive imagery of the Cartesian Theater keeps coming back to haunt us—laypeople and scientists alike—even after its ghostly dualism has been denounced and exorcized. [p. 107, original emphasis.] With no theatre, there

5427-422: The phenomena of interest by means of some observable and measurable effects they have. Sometimes multiple or competing alternative operationalizations for the same phenomenon are available. Repeating the analysis with one operationalization after the other can determine whether the results are affected by different operationalizations. This is called checking robustness. If the results are (substantially) unchanged,

5508-476: The physical stance with preservation of the intentional stance. This tentatively suggests a double dissociation of intentional and physical stances in the brain. However, most studies have found no evidence of impairment in autistic individuals' ability to understand other people's basic intentions or goals; instead, data suggests that impairments are found in understanding more complex social emotions or in considering others' viewpoints. Robbins and Jack point to

5589-399: The physical stance; the design stance; and the intentional stance: A key point is that switching to a higher level of abstraction has its risks as well as its benefits. For example, when we view both a bimetallic strip and a tube of mercury as thermometers, we can lose track of the fact that they differ in accuracy and temperature range, leading to false predictions as soon as the thermometer

5670-454: The position of the second light. Furthermore, the light seems to change colour as it moves across the visual field. A green light will appear to turn red as it seems to move across to the position of a red light. Dennett asks how we could see the light change colour before the second light is observed. Dennett claims that conventional explanations of the colour change boil down to either Orwellian or Stalinesque hypotheses, which he says are

5751-423: The possibility of the thermostat not being in the mood to work today because the weather is so nice. Whether to take a particular stance, then, is determined by how successful that stance is when applied. Dennett argues that it is best to understand human behavior at the level of the intentional stance, without making any specific commitments to any deeper reality of the artifacts of folk psychology . In addition to

5832-410: The presence of a certain object in the environment could be inferred by measuring specific features of the light it reflects. In these examples, the phenomena are difficult to directly observe and measure because they are general/abstract (as in the example of health) or they are latent (as in the example of the object). Operationalization helps infer the existence, and some elements of the extension, of

5913-429: The result of Descartes' continued influence on our vision of the mind. In an Orwellian hypothesis, the subject comes to one conclusion, then goes back and changes that memory in light of subsequent events. This is akin to George Orwell's Nineteen Eighty-Four , where records of the past are routinely altered. In a Stalinesque hypothesis, the two events would be reconciled prior to entering the subject's consciousness, with

5994-495: The results are said to be robust against certain alternative operationalizations of the checked variables. The concept of operationalization was first presented by the British physicist N. R. Campbell in his 'Physics: The Elements' (Cambridge, 1920). This concept spread to humanities and social sciences . It remains in use in physics. Operationalization is the scientific practice of operational definition , where even

6075-575: The same results, but the key insight of Einstein was to posit the Principle of Equivalence that the two operations would always produce the same result because they were equivalent at a deep level, and work out the implications of that assumption, which is the General Theory of Relativity. Thus, a breakthrough in science was achieved by disregarding different operational definitions of scientific measurements and realizing that they both described

6156-543: The sense of idiosyncratic. And insofar as we wish to cling to our subjective authority about the occurrence within us of states of certain types or with certain properties, we can have some authority—not infallibility or incorrigibility, but something better than sheer guessing—but only if we restrict ourselves to relational, extrinsic properties like the power of certain internal states of ours to provoke acts of apparent re-identification. So contrary to what seems obvious at first blush, there simply are no qualia at all. The key to

6237-546: The shapes. Further, Dennett (1987, p. 52) argues that, based on our fixed personal views of what all humans ought to believe, desire and do, we predict (or explain) the beliefs, desires and actions of others "by calculating in a normative system"; and, driven by the reasonable assumption that all humans are rational beings – who do have specific beliefs and desires and do act on the basis of those beliefs and desires in order to get what they want – these predictions/explanations are based on four simple rules: The core idea

6318-534: The three that Dennett outlined. They call it the phenomenal stance : Attributing consciousness, emotions, and inner experience to a mind. The explanatory gap of the hard problem of consciousness illustrates this tendency of people to see phenomenal experience as different from physical processes. The authors suggest that psychopathy may represent a deficit in the phenomenal but not intentional stance, while people with autism appear to have intact moral sensibilities, just not mind-reading abilities. These examples suggest
