The conception of truth-making, albeit in a rudimentary form, could already be discerned in the writings of G. E. Moore and E. Husserl in the early 1900s. A few years later it was more extensively exploited by William James. It was Wittgenstein, however, who gave the concept a precise meaning. In 1913/1914 Wittgenstein advanced a theory of possible worlds, only one of which was real. Every proposition suggests a part of a possible world which does or does not correspond to (...) parts of the real world. In the first case the proposition is true, in the second case false. Moreover, the part of the real world makes the sentence true. This part is a truth-maker, and the sentence is a truth-bearer. Surprisingly enough, Wittgenstein’s concept of truth-making had its family resemblance with William James’s conception of truth. In 1915 Wittgenstein stopped using the concept of truth-making—it was also not men-tioned in the Tractatus. Unfortunately, Russell did not notice this and in 1918 he adopted the concept of truth-making. In the 1930s, it was used by some second generation analytic philosophers (Schlick, Stebbing, and Wisdom). However, it became rather popular among analytic philosophers only in the 1980s. (shrink)

Between 1896 and 1898 Russell’s philosophy was considerably influenced by Hermann Lotze. Lotze’s influence on Russell was especially pronounced in introducing metaphysical—anthropological, in particular—assumptions in Russell’s logic and ontology. Three steps in his work reflect this influence. (i) The first such step can be discerned in the Principle of Differentiation, which Russell accepted in the Essay (finished in October 1986); according to this Principle, the objects of human cognition are segmented complexes which have diverse parts (individuals). (ii) After Russell reread (...) Lotze in June 1897, he claimed that the solution of the dilemma of pluralism or monism depends on how we see space and time: as relational or as adjectival? (iii) Russell decided for the relational conception only after he attended lectures by McTaggart on Lotze in January to February 1898. The lectures helped Russell to advance (from April to June 1898) a new theory of judgment according to which judgments relate terms (individuals) which are distinct one from another. Space and time moreover are series of moments and places with external relations between themselves. The discussions Russell had with Moore in May to June 1898 took place only after Russell developed this conception; they did not cause his philosophical turn. (shrink)

Resumo: Franz Brentano não foi uma figura solitária que propôs sua filosofia isolada de outros filósofos contemporâneos na Alemanha, tal como alguns neo-brentanianos reivindicaram nos últimos anos. O objetivo deste artigo é corrigir tais concepções equivocadas estabelecendo que Brentano desenvolveu sua psicologia filosófica engajado ativamente no rico contexto histórico-intelectual e acadêmico de seu tempo - em particular, sob a influência de Hermann Lotze. Especificamente, Brentano: (i) adota de Lotze a ideia de que juízo não é apenas uma associação de ideias, (...) mas uma asserção do conteúdo; (ii) também adota a ideia de Lotze de que o conteúdo da percepção é algo dado; (iii) a noção brentaniana de intencionalidade também foi herdada de Lotze, (iv) bem como o método da psicologia descritiva; (v) finalmente, Lozte e Brentano concordaram ao admitir que percepção e conhecimento estão intrinsicamente conectados às emoções. Ao mesmo tempo, há ao menos dois pontos nos quais Brentano discorda de Lotze: (i) ele critica a teoria da percepção do signo local, bem como o atomismo de Lotze. Estas eram claramente teorias construtivistas inspiradas por Kant. (ii) Brentano também critica o princípio do teleomecanismo de Lotze, influenciado pelos idealistas alemães. (shrink)
