Systematicity via Monadicity (draft 24Jan07)

چکیده
Paul M. Pietroski (University of Maryland) Thinking requires concepts. Talking requires words. We humans have thoughts that are composed of concepts, which we can express with words that can be combined to form sentences, which we can use to express thoughts. I take this as given. But how are human concepts related to the words that children naturally acquire? Do words compose in the same way, or ways, that concepts compose? Does lexicalization leave our concepts unchanged? Are human concepts especially composable? I offer a proposal according to which lexicalization is a creative process, and the composability of words makes human concepts distinctive. 1. The Idea: Words as Monadicizers When a concept is lexicalized, I’ll argue, it is linked to an analytically related monadic concept. For example, the dyadic concept CHASE(_, _) might be linked to CHASE(_), a concept that applies to certain events. But the monadic concept, which may be formed in the course of lexicalization, is not a constituent of the dyadic concept. Analysis can take the form of abstraction, as opposed to decomposition. Like Fodor (1998), I think words tend to indicate atomic concepts, which vary in adicity. Though as Frege (1884) showed, it can be useful to impose analyses on thoughts; see Horty (forthcoming). My suggestion is that the human language faculty imposes monadic analyses, in a constrained way, letting us build new complex concepts by simple conjunction. Suppose that concepts are elements of one or more mental languages, whose sentences include PAST+CHASE(FIDO, FELIX),; where this mental sentence is the internal translation of the spoken sentence ‘Fido chased Felix’. Then setting tense aside, for a moment, the English sentence indicates a thought of the form ú(:, B) . Given standard principles of inference, any j k

An Elementary Theory of the Category of Locally Compact Locales
The category of locally compact locales over any elementary topos is characterised by means of the axioms of abstract Stone duality (monadicity of the topology, considered as a selfadjoint exponential Σ(−), and Scott continuity, Fφ = ∃`. F (λn. n ∈ `)∧∀n ∈ `. φn), together with an “underlying set” functor that is right adjoint to the inclusion of the full subcategory of overt discrete objects (...
متن کاملThe Proper Treatment of Semantic Systematicity
Connectionist-minded philosophers, including Clark and van Gelder, have espoused the merits of viewing hiddenlayer, context-sensitive representations as possessing semantic content, where this content is partially revealed via the representations' position in vector space. In recent work, Bodén and Niklasson have incorporated a variant of this view within their conception of semantic systematic...
متن کاملSystems from Sequences: an Iterated Learning Account of the Emergence of Systematic Structure in a Non-Linguistic Task
Systematicity is a basic property of language and other culturally transmitted behaviours. Utilising a novel experimental task consisting of initially independent sequence learning trials, we demonstrate that systematicity can unfold gradually via the process of cultural transmission.
متن کاملOn the Systematicity of Language and Thought
The last twenty years or so have seen a lot of discussion about systematicity-roughly the idea that if a person's repertoire contains the sentence/thought thatJohn loves Mary, then her repertoire also contains the sentence/thought that Mary loves John.' Much of the discussion of systematicity has focused on the technical question of whether and how connectionists can explain the systematicity o...
متن کاملM-completeness Is Seldom Monadic over Graphs
For a set M of graphs the category CatM of all M-complete categories and all strictly M-continuous functors is known to be monadic over Cat. The question of monadicity of CatM over the category of graphs is known to have an affirmative answer when M specifies either (i) all finite limits, or (ii) all finite products, or (iii) equalizers and terminal objects, or (iv) just terminal objects. We pr...
