Malebranche affirmed the existence of the material world on the grounds of faith rather than reason. Religious dogma demanded the existence of the material world and Malebranche, the priest, acquiesced. Reason found the existence of the material world doubtful and, indeed, unnecessary. The existence of a material world different from and apart from minds conflicts with the proof of the economy of God's nature which Malebranche offered. Further, in inquiring into the probable nature of the material world Malebranche never successfully (...) avoided the conclusion that apart from a mind the material world is nothing. Malebranche thus came close to proving that the assumption of a material world is unnecessary even for theology, but the explicit statement of such a conclusion would have been too open a break with the church for a faithful member. Surely, however, the weight of Malebranche's reasoning and its implications for immaterialism would not be lost on one already interested in arguments against materialism. Berkeley's interest was such and Luce has shown that Berkeley read Malebranche carefully. Malebranche was the only thinker clearly inclining toward immaterialism whom Berkeley read. Is Malebranche, then, not the source of Berkeley's immaterialism? (shrink)
