while Spinoza only takes notice of these ordinary conceptions, and the highest point of view he reaches in regard to them is that they sink and disappear in the one Substance, Locke on the contrary examines the genesis of these conceptions, while Leibnitz opposes to Spinoza the infinite multiplicity of individuals, although all these monads have one monad as the basis of their Being. Both Locke and Leibnitz therefore came forward as opponents of the above-mentioned one-sidedness of Spinoza. 3. MALEBRANCHE. The philosophy of Malebranche is in point of matter entirely identical with that of Spinoza, but it has another, a more religious and more theological form; on account of this form it never encountered the opposition met with by Spinoza, and for the same reason Malebranche has never been reproached with Atheism. Nicholas Malebranche was born at Paris in 1638. He was sickly and deformed in body, and was hence brought up with great care. He was diffident and loved solitude; in his twenty-second year he entered the _congrégation de l’oratoire_, a sort of spiritual order, and devoted himself to the sciences. In passing a bookseller’s shop he happened accidentally to see Descartes’ work _De homine_; he read it, and it interested him greatly—so much so that the reading of it brought on severe palpitation and he was forced to cease. This decided his future life; there awoke in him an irrepressible inclination for Philosophy. He was a man of most noble and gentle character, and of the most genuine and unswerving piety. He died at Paris in 1715, and in the seventy-seventh year of his age.[210] His principal work bears the title: _De la recherche de la vérité_. One part of it is entirely metaphysical, but the greater part is altogether empirical. For instance, Malebranche in the first three books treats logically and psychologically of the errors in sight and hearing, in the imagination and understanding.
