In the paper we discuss criticisms against David Armstrong’s general theory of truthmaking by Gonzalo Rodriguez-Pereyra, Peter Schulte and Benjamin Schnieder, and conclude that Armstrong’s theory survives these criticisms. Special attention is given to the problems concerning Entailment Principle, Conjunction Thesis, Disjunction Thesis and to the notion of explanation.

Noam Chomsky is among the most influential contemporary thinkers. Peter Wilkin looks in particular at the philosophical basis of his social and political thought, especially his ideal about power, knowledge and human nature. He shows how Chomsky's ideas can help to defend naturalism as in social and political thought. Chomsky's critical writings of social inquiry and his normative ideas on libertarian socialism and human emancipation are interpreted as synthesising a number of important ideas and approaches at a time when these (...) ideas have fallen out of favour.

One of the key concepts of naturalized epistemology as well as the cognitive sciences that stem from it is the naturalized concept of mental representation. Within this naturalized concept, many attempts have been made to unify the notion of representation error. This text makes an attempt to argue against the adequacy of using a naturalized concept of representation error as well as casts doubt on the wide program of naturalizing concepts related to human conceptuality.

Jednym z kluczowych pojęć znaturalizowanej epistemologii, a także wyrastających z niej nauk kognitywistycznych jest znaturalizowane pojęcie reprezentacji poznawczej. W ramach tego znaturalizowanego pojęcia próbuje się jednolicie ująć pojęcie błędu reprezentacyjnego. W tekście pokazane są argumenty przeciwko adekwatności stosowania znaturalizowanego pojęcia błędu reprezentacyjnego oraz wątpliwości co do tak szerokiego programu naturalizacji zagadnień związanych z ludzką pojęciowością.

The aim of the thesis is to provide the foundations for a representation-based theory of meaning, i.e. a theory of meaning that encompasses the psychological level of cognitive representations. This is in opposition to the antipsychologist goals of the Fregean philosophy of language and represents the results of a joint analysis of multiple philosophical problems in contemporary philosophy of language, which, as argued in the tesis, stem from the lack of recognition of a cognitive level in language. In the thesis, (...) I first provide and argue a definition of cognitive/mental representations based on results in developmental psychology as well as theoretical considerations. Then, I use the definition to build upon it a richer theory of concepts and apply it to various philosophical conundra. The problems tackled include the problem of proper names (for which a solution is proposed that respects the post-Kripkean criticism), a unified meaning postulate for modalities and the epistemology and ontology of mathematical terms. The thesis concludes with a proposed application of the newly acquired framework to select social aspects of language use. (shrink)
