among nicolas malebranche’s most influential contributions to philosophy are his defense of occasionalism, his highly original theodicy, and his philosophical method elaborated in greatest detail in his magnum opus De la Recherche de la vérité. In his account of occasionalism, Malebranche argues that finite things have no causal power and that God is the only true causal agent. Malebranche’s theodicy—his attempt to reconcile the existence of evil in the world with the existence of an all-good and all-powerful God—is most thoroughly (...) developed in Traité de la nature et de la grâce. Malebranche’s theodicy revolves around a.. (shrink)

In this paper, I argue that Kant adopted, throughout his career, a position that is much more akin to classical accounts of epigenesis, although he does reject the more radical forms of epigenesis proposed in his own time, and does make use of preformationist sounding terms. I argue that this is because Kant thinks of what is pre-formed as a species, not an individual or a part of an individual; has no qualm with the idea of a specific, teleological principle (...) or force underlying generation, and conceives of germs and predispositions as specific constraints on such a principle or force. Neither of these conceptions of what is “preformed”, I argue, is in strict opposition to classical epigenesis. I further suggest that Kant’s lingering use of preformationist terminology is due to his belief that this is required to account for the specificity of the specific generative force; his resistance towards the unrestricted plasticity of the generative force in radical epigenesis, which violates species-fixism; and his insistence on the internal, organic basis of developmental plasticity and variation within species. I conclude by suggesting that this terminological and interpretative peculiarity is partly due to a larger shift in the natural philosophical concerns surrounding the debate on epigenesis and preformation. Specifically, it is a sign that the original reasons for resisting epigenesis, namely its use of specific, teleological principles and its commitment to the natural production of biological structure, became less of a concern, whereas unrestricted plasticity and its undermining of fixism became a real issue, thereby also becoming the focal point of the debate.

The focus of this paper is a fascinating but hitherto unstudied 1742 manuscript treatise by Johannes Daniel Schlichting (1705–1765) titled “Sapientiæ Problema” that contains something extremely rare in the mid-eighteenth century: a full-blown speculative cosmogony. As this article reveals, Schlichting developed a distinctive vital liquid matter in an effort to account for the generation of all natural bodies and combat the stamina-based theories that were dominant in his day. He hoped that his treatise would be published in the Philosophical Transactions (...) of the Royal Society, but an accompanying abridgment by the FRS Henry Baker (1698–1774) strongly implies that Schlichting’s speculative bent and desire to divulge causal explanations were unacceptable to the Englishman and generally ill-suited to the intellectual climate of mid-century England.

O presente artigo tem como objetivo analisar a articulação feita por Malebranche entre a física mecanicista o finalismo em sua teoria da preexistência dos germes. Pretendemos mostrar como essa articulação permite que o oratoriano forneça uma resposta ao problema, deixado por Descartes, da explicação mecânica da geração dos corpos organizados. Assim, tomamos como ponto de partida as tentativas de Descartes de fornecer uma explicação mecânica à geração para, em seguida, analisar a noção de finalidade no ocasionalismo de Malebranche e, finalmente, (...) a articulação entre mecanicismo e finalismo na teoria da preexistência dos germes.
