This essay gives a new interpretation of Hume's second thoughts about minds in the Appendix, based on a new interpretation of his view of composition. In Book 1 of the Treatise, Hume argued that, as far as we can conceive it, a mind is a whole composed by all its perceptions. But—this essay argues—he also held that several perceptions form a whole only if the mind to which they belong supplies a “connexion” among them. In order to do so, it (...) must contain a further perception or perceptions. But when the perceptions in question are all of those belonging to a given mind—as in the section “Of personal identity” and the Appendix—there cannot be a further perception in that mind, and so those perceptions do not form a whole. Hence, Hume's views were inconsistent. This essay argues that, unlike most others, this interpretation explains his retreat to skepticism in the Appendix. (shrink)

I survey some of the connections between the metaphysics of the relation between mind and matter, and quantum theory’s measurement problem. After discussing the metaphysics, especially the correct formulation of physicalism, I argue that two state-reduction approaches to quantum theory’s measurement problem hold some surprises for philosophers’ discussions of physicalism. Though both approaches are compatible with physicalism, they involve a very different conception of the physical, and of how the physical underpins the mental, from what most philosophers expect. And one (...) approach exemplifies a a problem in the definition of physicalism which the metaphysical literature has discussed only in the abstract. A version of the paper has appeared in Consciousness and Human Identity, ed. John Cornwell, OUP 1998. (shrink)

http://dx.doi.org/10.5007/1808-1711.2012v16n2p229 Tanto no Tratado da Natureza Humana como na Investigação sobre o Entendimento Humano , Hume mostra-se convencido de que “não há acaso no mundo”, e que “aquilo que o vulgo chama de acaso não passa de uma causa secreta e escondida”. Essa tese desempenha papel crucial em sua análise do livre-arbítrio e, conseguintemente, da responsabilidade moral; é também um elemento importante em sua discussão sobre os milagres. No entanto, o próprio Hume ofereceu, no Tratado , um argumento convincente para (...) mostrar que o princípio de causalidade, segundo o qual tudo o que começa a existir tem uma causa, não pode ser conhecido a priori , por intuição ou demonstração. Logo, essa “opinião tem necessariamente de provir da observação e experiência”. O presente trabalho examina essa tese, mostrando, inicialmente, qual era a proposta de Hume para fundar na experiência o princípio de causalidade, e depois qual, de fato, teria sido o mais robusto fundamento para esse princípio: a mecânica newtoniana. Explica-se, por fim, como esse fundamento empírico indireto e o próprio argumento de Hume foram solapados pela física quântica, no século XX. (shrink)

In this paper, I briefly present the regularity and necessity views and assess their difficulties. I construe scientific laws as universal propositions satisfied by empirically successful scientific models and made — approximately — true by the real systems represented, albeit partially, by these models. I also conceive a scientific theory as a set of models together with a set of propositions, some of which are laws. A scientific law is a universal proposition or statement that belongs to a scientific theory. (...) Scientific laws also are laws of nature since we can provide arguments in favour of natural causal powers that ground the truth of laws. I argue that the truth of counterfactual conditional statements and the occurrence of regularities in nature provide good reasons to believe that real causal powers exist in nature and that the truth of scientific laws is based on a metaphysics of nature.
