PHIL 58009 Disjunctivism and the Philosophy of Language
Disjunctivist accounts of human capacities always turn on some form of rejection of (what we will call in this course) a layer-cake assumption. One particularly widespread version of the latter sort of assumption, when asserted as a thesis about the nature of our cognitive faculties and their relation to one another, goes like this: The natures of our sentient and rational capacities respectively are such that we could possess one of these capacities, as a form of cognition, without possessing the other. The underlying assumption is that at least one of these capacities is a self-standing cognitive capacity – one which could operate just as it presently does in us in isolation of the other. This course will begin by examining the counterpart assumption in the philosophy of language, when it is asserted as a thesis about the relation between the aspects of language we respectively apprehend through our power of sensory perception (for example, in recognizing signs) and through our power of intellectual comprehension (for example, in grasping a meaning). One tendency, for example, which we find in much contemporary philosophy of language is to conceive of the linguistic expression as a composite notion to be analyzed in terms of a kind of mere physical mark or acoustic noise to which something further — a meaning or use — is assigned or added in order to yield a fully linguistic expression. Some of the more penetrating philosophers of the past century have noticed that such a conception of language (once it is strictly thought through) appears to encounter insurmountable difficulties. This course will begin by looking at the work of some thinkers in the history of philosophy and linguistics who have challenged such a conception. We will then move on to considering further varieties of layer-cake assumptions and disjunctivist responses thereto that arise in the philosophy of language pertaining to the following further ten interrelated topics: (1) the relation between phonetics and phonology, (2) the relation between phonemes and morphemes, (3) between words and sentences, (4) between infant and adult forms of linguistic capacity, (5) between first and second language acquisition, (6) between orality and literacy in the cultural phases of the historical development of a single natural language, (7) between the pre- and post-punctuation phases in the historical development of the written form of a modern natural language, (8) between the written and spoken sign forms within a single modern natural language, (9) between a logically regimented artificial sign system and a living natural language, and (10) between diverse linguistic forms of speech and/or writing within a single cultural form of life marked by diglossia or heteroglossia.
