Causal and Logical Necessity in Malebranche's Occasionalism

Abstract

The famous Cartesian Nicolas Malebranche (1638-1715) espoused the occasionalist doctrine that ‘there is only one true cause because there is only one true God; that the nature or power of each thing is nothing but the will of God; that all natural causes are not true causes but only occasional causes’ (LO, 448, original italics). One of Malebranche's well-known arguments for occasionalism, known as, the ‘no necessary connection’ argument (or, NNC) stems from the principle that ‘a true cause… is one such that the mind perceives a necessary connection between it and its effect’ (LO, 450).
