    • n Spinozism The metaphysical doctrine of Baruch (afterward Benedict) de Spinoza (1632—1677), a Spanish Jew, born at Amsterdam. Spinoza's chief work, the “Ethics,” is an exposition of the idea of the absolute, with a monistic theory of the correspondence between mind and matter, and applications to the philosophy of living. It is an excessively abstruse doctrine, much misunderstood, and too complicated for brief exposition. The style of the book, an imitation of Euclid's “Elements,” is calculated to repel the mathematician and logician, and to carry the attention of the ordinary reader away from the real meaning, while conveying a completely false notion of the mode of thinking. Yet, while the form is pseudomathematical the thought itself is truly mathematical. The main principle is, indeed, an anticipation in a generalized form of the modern geometrical conception of the absolute, especially as this appears in the hyperbolic geometry, where the point and plane manifolds have a correspondence similar to that between Spinoza's worlds of extension and thought. Spinoza is described as a pantheist; he identifies God and Nature, but does not mean by Nature what is ordinarily meant. Some sayings of Spinoza are frequently quoted in literature. One ot these is omnis determinatio est negatio, “all specification involves exclusion”; another is that matters must be considered sub specie æternitatis, “under their essential aspects.”
