Items in many non-linguistic representational systems such as maps possess propositional form by this characterization. Logical form, however, is possessed by items that belong to representational systems that include distinct symbols for logical operators.
So, Fire nearby. The extent and strength of first-person warrant rests ultimately on the empirical reliability of such reports, just as the warrant of observation reports does.
See Astington et al. The idea is that if folk psychology is like a theory, then, like any theory, it could be superseded and replaced by a better theory as scientific psychology and neuroscience progress.
Sellars himself, however, was unmoved by this idea, because the concepts of folk psychology of the manifest image are not focused solely or maybe even principally on the description and explanation of phenomena.
In the course of science, better descriptions of what is going on in our heads when we think and sense will be developed, but such descriptions could have only a part of the function of mentalistic language.
The language of agency, to which we will shortly return, is indispensable and cannot be replaced by the language of any scientific theory.
The context is, again, the idea that our concepts of sensory states are, in some important ways, like theoretical concepts.
Concepts of sensory states, however, are introduced to explain different phenomena from those that concepts of intentional states are introduced to explain.
They are originally introduced to explain illusions, hallucinations and such, cases in which people sincerely report and behave as if perceiving something that is not there.
Once introduced for those purposes, however, such concepts must be applied generally: we cannot think that we have sensations only in cases of illusion and hallucination.
A philosophically satisfactory theory of the sensory must account for the complexity and peculiarities of the language of sensory experience, both illusory and veridical.
Sellars then argues that the language of perceptible qualities and relations cannot be reduced to or replaced by any vocabulary we currently project to be adequate to the behavior of mere physical objects.
The argument for this claim is complex. Nonetheless, Sellars argues that, in the end, sensory states will turn out to be physical states of a very particular ilk that exist only in the context of living organisms.
They are, in the terminology Sellars developed with his colleague Paul Meehl, physical 1 but not physical 2 , where.
Sensory states are, thus, historically emergent in the universe, but nonetheless physical: the effort to provide a complete description and explanation of the physics of sentient beings will expand the theoretical primitives utilized in that science, relocating the logical space of the proper and common sensibles within physics as a primitive vocabulary.
The quasi-history of our sensory concepts starts with a mythical beginning in which the concepts that we think of as concepts of sensible qualities are taken to be concepts of the very substance of things.
But treating sensibles as substantive cannot go very far; it does not provide a useful way of classifying, explaining, and predicting the behavior of the things we encounter.
The sensibles soon become treated as occurrent qualities of substances with complex causal profiles.
The view that the sensibles are modifications of substances is then supplemented with the notion that they possess a subsidiary and analogous being-for-mind that explains our ability to apprehend them directly unlike causal dispositions and to be sometimes mistaken about their presence.
In the current manifest image, this is how we think of sensible properties, according to Sellars. Physical objects are colored, odorous, etc.
The rise of a new, atomistic science has started to push our conception of the sensibles in new directions. First, it encourages a reinterpretation of the distinction between the common and the proper sensibles.
The common sensibles, those available to more than one sense, include such geometric and dynamic properties as shape and motion; these apply to physical objects and their microconstituents, because physical explanations exploit such properties.
The proper sensibles are the qualities available only to specific senses, including colors, odors, etc.
Primary and secondary qualities are distinct in kind, and secondary qualities are demoted to second-class, subjective status.
They exist only in the mind, as states of the perceiver. The next move seems clear: the mind itself is subjected to scientific investigation and becomes increasingly identified with the brain or central nervous system.
But the proper sensibles can no more exist in the brain than in any other kind of matter. This brings us to our current predicament: we are unable to find a place in the world for the proper sensibles, which have been brutually and metaphysically severed from the common sensibles, even though color and extension, for example, seem intrinsically related.
This argument poses a challenge to materialism by purporting to show that the proper sensibles cannot be reduced to properties or relations of more basic physical particles that lack these properties.
Sellars carefully distinguishes between propositional seeing and objectual seeing, and between seeing an object and what we see of the object. All perceptual experience, in his view, has conceptual content, which shows up in the propositional content of a seeing or in what we see an object as.
But he is also firmly convinced that not everything in perception is present as conceptual content, as something thought of or believed in. What we see of the ice cube is present to us in a different way from that in which the merely conceptual content of our experience is present to us.
What is needed is:. Sellars takes it that this claim states a structural feature of the manifest image. It is, note, incompatible with views that reject the idea that there is a nonconceptual component in perception—which Sellars would think are confused about the place of sensible qualities in the manifest image.
The grain argument is meant to cut off reductive replies to these questions. The notion of a reduction must also be specified, for it is notoriously multivalent.
But the proper sensibles are not reducible in this way to the properties and relations of micro-objects. Sense impressions are posited to explain how systems of particles appear the way they do; they cannot themselves turn out to be another kind of system of particles, or the explanation fails.
If this argument is right, then the postulation of sense impressions must differ in some important ways from the kind of theoretical postulation that typically results in a belief in new microentities.
And this is what Sellars argues. Sellars holds, then, that the logical space of the sensible qualities has been successively recategorized in different stages of human development.
He proposes that this history will take one more turn as science develops further: unable to reduce or eliminate the sensibles, science will postulate a distinctive set of entities, sensa , to be the final embodiment of the sensible qualities, physical 1 but not physical 2.
Sellars is a physicalist about color, not because he thinks colors can be reduced to more basic properties and relations of physical objects, but because physics will have to expand to accommodate the sensible qualities, color included, as primitive entities.
See Rosenberg and deVries , Chapter 8, for more exploration of this issue. Sellars was a significant philosopher of science and a staunch defender of scientific realism.
We can start with the distinction between observational and theoretical vocabularies. Many empiricists were wedded to the myth of the given, assuming that there is a privileged observation vocabulary.
The meanings of observation terms were determined by their relation to what is given and were thus unrevisable or incorrigible.
This vocabulary grounds the meaning of all empirical language. Two kinds of generalizations were recognized: 1 empirical generalizations formulated in the observation language and justified by straightforward inductive methods, and 2 higher-level generalizations formulated in a more abstract, theoretical idiom including novel theoretical posits.
This theoretical language consists of terms invented in order to better organize, generalize, and make connections among the assertions and generalizations made in the observation language.
The ideal would be a formal axiomatic structure that would allow a deduction of the empirical generalizations which, combined with statements of initial conditions, permit a deduction of particular empirical facts thus explaining their truth.
We are committed to the existence of the given, for that is what ties thought to reality. Theories, however, are merely tools to enable us to explain observation-level empirical generalizations.
Presumably, some empirical generalizations may be first derived with the help of a theory, but they are subject to more direct investigation and corroboration, so the theory is not essential to it.
Thus, there is no ontological commitment to any entities that theories postulate; they can be viewed as convenient fictions, devices of calculation.
Sellars thinks that this instrumentalist picture gets almost everything wrong. There is no given, so it can play no semantic role. Meanings are functional roles in language usage, and nothing in principle prevents a term that might originally have arisen as part of a theory from acquiring a role in observation reports.
Furthermore, what is observable depends on the techniques and instruments employed, and these are often loaded with theoretical baggage.
A good theory, according to Sellars, does not just explain the observation-level empirical generalizations, it also explains why those empirical generalizations are as good and as wrong as they are.
The Boyle-Charles ideal gas law works well in most conditions, but does not predict the behavior of gasses under extreme temperatures or pressures.
The van der Waals equation, explicitly formulated with the theory of statistical thermodynamics in mind, allows us to see why the Boyle-Charles law is as good as it is and why it breaks down where it does.
Thus, to have good reason to accept a theory is to have good reason to believe in the existence of those entities it postulates. Prescribing, evaluating, and negotiating are equally indispensable dimensions of language use that go beyond the descriptive brief of science.
Sellars also has a distinctive treatment of scientific laws. Laws are standardly treated as generalizations; they are distinguished from accidental generalizations because laws have a modal force capable of supporting counterfactuals.
Though they have descriptive content, statements of laws serve a different function in our language.
As mentioned above, Sellars treats modals uniformly as material-mode metalinguistic speech expressing the inferential commitments and priorities embedded in the language.
So, saying that it is a law of nature that e. Furthermore, Sellars does not think of language as a fixed entity. Indeed, in his conception, the job of the sciences is to methodically revise and replace the resources available for description and explanation.
Conceptual change is the very essence of science. In his view, laws of nature are proposed connections among concepts or terms that, pending possible empirical disconfirmation, can be rationally attached to the concepts.
In: The Oxford Handbook of Hegel. Oxford: Oxford University Press, The sociality and historicity of reason, the proper treatment of space and time, conceptual holism, inferentialism, the reality of conceptual structure, the structure of experience, and the nature of normativity are the central concerns of Pittsburgh Hegelianism.
