The endeavor to understand is the first and only basis of virtue. - Benedictus de Spinoza

In Spinoza, at the origin of the Modern world, metaphysical theory and the theory of science are given in complete agreement for the first time. They represent the alternative to the entire subsequent path of metaphysics and of the bourgeois theory of science. Spinoza lives as an alternative: Today this alternative is real. The Spinozian analytic of full space and open time are becoming an ethics of liberation in all the dimensions that this discourse constructs and makes available.

As regards the philosophy of Spinoza, it is very simple, and on the whole easy to comprehend; the difficulty which it presents is due partly to the limitations of the method in which Spinoza presents his thoughts, and partly to his narrow range of ideas, which causes him in an unsatisfactory way to pass over important points of view and cardinal questions. Spinoza's system is that of Descartes made objective in the form of absolute truth. The simple thought of Spinoza's idealism is this: The true is simply and solely the one substance, whose attributes are thought and extension or nature: and only this absolute unity is reality, it alone is God. It is, as with Descartes, the unity of thought and Being, or that which contains the Notion of its existence in itself. The Cartesian substance, as Idea, has certainly Being included in its Notion; but it is only Being as abstract, not as real Being or as extension (supra, p. 241). With Descartes corporeality and the thinking 'I' are altogether independent Beings; this independence of the two extremes is done away with in Spinozism by their becoming moments of the one absolute Being. This expression signifies that Being must be grasped as the unity of opposites; the chief consideration is not to let slip the opposition and set it aside, but to reconcile and resolve it. Since then it is thought and Being, and no longer the abstractions of the finite and infinite, or of limit and the unlimited, that form the opposition (supra, p. 161), Being is here more definitely regarded as extension; for in its abstraction it would be really only that return into itself, that simple equality with itself, which constitutes thought (supra, p. 229). The pure thought of Spinoza is therefore not the simple universal of Plato, for it has likewise come to know the absolute opposition of Notion and Being.

What knowing means. - Non ridere, non lugere, neque detestari, sed intelligere! says Spinoza as simply and sublimely as is his wont. Yet in the final analysis, what is this intelligere other than the way we become sensible of the other three? A result of the different and conflicting impulses to laugh, lament, and curse? Before knowledge is possible, each of these impulses must first have presented its one-sided view of the thing or event; then comes the fight between these one-sided views,...
