This short piece discusses the sense-reference, intension-extension, and, from AI (artificial intelligence), the declarative knowledge-procedural knowledge dichotomies with an eye towards clarifying the difficult question of authorship in the case of computer-generated works.

Michael Dummett has argued that a formal semantics for our language is inadequate unless it can be shown to illuminate to our actual practice of speaking and understanding. This paper argues that Frege’s account of the semantics of predicate expressions according to which the reference of a predicate is a concept (a function from objects to truth values) has exactly the required characteristics. The first part of the paper develops a model for understanding the distinction between objects and concepts as (...) an ontological distinction. It argues that, ontologically, we can take a Fregean function to be generated by a property detection device that can register for any object the presence or absence of that property. This provides a direct connection between the semantics of sentences and the structure of perceptual judgment. The second part of the paper deals with arguments that have been mounted against the coherence of Frege’s semantics. It argues that some of these are question begging, while others are correct in so far as Frege’s claim is untenable if we assume that the syntactic categories singular term and predicate are primary, and the ontological categories are simply projections of these syntactic categories. However, the objections dissipate once we recognize that an independent ontological characterization of the distinction is available. (shrink)

Neural correlates exist for a basic component of logical formulae, PREDICATE(x). Vision and audition research in primates and humans shows two independent neural pathways; one locates objects in body-centered space, the other attributes properties, such as colour, to objects. In vision these are the dorsal and ventral pathways. In audition, similarly separable “where” and “what” pathways exist. PREDICATE(x) is a schematic representation of the brain's integration of the two processes of delivery by the senses of the location of an arbitrary (...) referent object, mapped in parietal cortex, and analysis of the properties of the referent by perceptual subsystems. The brain computes actions using a few “deictic” variables pointing to objects. Parallels exist between such nonlinguistic variables and linguistic deictic devices. Indexicality and reference have linguistic and nonlinguistic (e.g., visual) versions, sharing the concept of attention. The individual variables of logical formulae are interpreted as corresponding to these mental variables. In computing action, the deictic variables are linked with “semantic” information about the objects, corresponding to logical predicates. Mental scene descriptions are necessary for practical tasks of primates, and preexist language phylogenetically. The type of scene descriptions used by nonhuman primates would be reused for more complex cognitive, ultimately linguistic, purposes. The provision by the brain's sensory/perceptual systems of about four variables for temporary assignment to objects, and the separate processes of perceptual categorization of the objects so identified, constitute a pre-adaptive platform on which an early system for the linguistic description of scenes developed. Key Words: argument; attention; deictic; dorsal; logic; neural; object; predicate; reference; ventral. (shrink)

Presents a series of generalizations of distributivity operators across a type hierarchy, in order to account for collective-distributive ambiguities for non-subject arguments.

THIS ARTICLE CLARIFIES A DISTINCTION MADE BY ME ELSEWHERE BETWEEN PRIMARY AND SECONDARY TESTS FOR THE APPLICATION OF A CONCEPT. IF THE PRIMARY TESTS ARE SATISFIED, THEN OF LOGICAL NECESSITY THE CONCEPT APPLIES, BUT SATISFACTION OF THE SECONDARY TESTS IS ONLY GOOD EMPIRICAL EVIDENCE FOR THE APPLICABILITY OF THE CONCEPT. THIS ARTICLE IS A REPLY TO ONE BY SLOTE (’A GENERAL SOLUTION TO GOODMAN’S RIDDLE?’ ANALYSIS, DECEMBER 1968) CHALLENGING MY EARLIER USE OF THIS DISTINCTION (’GRUE’ ANALYSIS, MARCH 1968) TO PROVIDE (...) A SOLUTION TO GOODMAN’S RIDDLE. (shrink)

IF "ALL A’S ARE B" AND "ALL A’S ARE C" ARE BOTH EQUALLY WELL SUPPORTED BY OBSERVATIONS SO FAR, YET YIELD CONFLICTING PREDICTIONS, WHICH OUGHT WE TO ADOPT? GOODMAN’S CONFLICT BETWEEN "ALL EMERALDS ARE GREEN" AND "ALL EMERALDS ARE GRUE" IS A SPECIAL CASE OF SUCH CONFLICT, WHICH MAY BE DEALT WITH BY A RULE STATING THAT WE OUGHT NOT TO PROJECT POSITIONAL IN PREFERENCE TO QUALITATIVE PREDICATES. THIS PAPER ATTEMPTS TO ELUCIDATE THE RULES GOVERNING A LARGER CLASS OF SUCH (...) CONFLICTS, IN CASES WHERE ONE PREDICATE B IS "EPISTEMOLOGICALLY PRIOR" TO ANOTHER ONE C. (shrink)

CONTRARY TO GOODMAN’S VIEW, A CLEAR DISTINCTION CAN BE MADE BETWEEN QUALITATIVE AND POSITIONAL PREDICATES. HENCE WE CAN EXPLAIN THAT WE OUGHT TO PROJECT ’GREEN’ RATHER THAN ’GRUE’ BECAUSE THE LATTER IS A POSITIONAL PREDICATE, RATHER THAN BECAUSE THE LATTER IS LESS WELL ENTRENCHED. A PREDICATE IS POSITIONAL IF, TO FIND OUT AS CERTAINLY AS WE CAN WHETHER IT APPLIES TO AN OBJECT, WE HAVE TO FIND OUT THE LATTER’S SPATIO-TEMPORAL LOCATION.

In this paper I explore how the tenseless copula is to be interpreted in sentences of the form “ a is F at t ”, where “ a ” denotes a persisting, changeable object, “ F ” stands for a prima facie intrinsic property and “ t ” for a B-time. I argue that the interpretation of the copula depends on the logical role assigned to the time clause. Having rejected the idea that the time clause is to be treated (...) as a sentence operator, I argue: (1) that if “at t ” is thought of as being associated with “ a ” or “ F ”, then the tenseless copula is most plausibly read as an “is” simpliciter ; and (2) that if “at t ” is treated as being associated with the copula, then the tenseless copula is most plausibly understood as expressing a disjunction of tensed copulas. I end the paper by explaining the importance of the issue. I indicate the ramifications interpretation of the tenseless copula has for the so-called problem of temporary intrinsics. (shrink)

According to Quine, terms of divided reference like 'rabbit' have two sorts of problems: problems of direct and deferred ostension. Hence the reference of these terms is inscrutable. This article holds that the problems of deferred ostension can be handled by Goodman's theory of projection, and that the problems of direct ostension turn out to be pedestrian problems of signs.
