You were one of the noblest, the most genuine people, who have ever walked this earth. And though both friend and foe know this, I don't think it unw… - Benedictus de Spinoza

The shortcoming thus acknowledged to attach to the content turns out at the same time to be a shortcoming in respect of form. Spinoza puts substance at the head of his system, and defines it to be the unity of thought and extension, without demonstrating how he gets to this distinction, or how he traces it back to the unity of substance. The further treatment of the subject proceeds in what is called the mathematical method. Definitions and axioms are first laid down: after them comes a series of theorems, which are proved by an analytical reduction of them to these unproved postulates. Although the system of Spinoza, and that even by those who altogether reject its contents and results, is praised for the strict sequence of its method, such unqualified praise of the form is as little justified as an unqualified rejection of the content. The defect of the content is that the form is not known as immanent in it, and therefore only approaches it as an outer and subjective form. As intuitively accepted by Spinoza without a previous mediation by dialectic, Substance, as the universal negative power, is as it were a dark shapeless abyss which engulfs all definite content as radically null, and produces from itself nothing that has a positive subsistence of its own.

Goethe—not a German event, but a European one: a magnificent attempt to overcome the eighteenth century by a return to nature, [...] He sought help from history, natural science, antiquity, and also Spinoza, [...]

The latter [Descartes] had sharply divided nature into mind and matter, i.e., thinking and extended substance, and had also placed God and the world in complete opposition to each other; Spinoza also, so long as he was a Cartesian, taught all that in his “Cogitatis Metaphysicis,” c. 12, i. I., 1665. Only in his later years did he see the fundamental falseness of that double dualism; and accordingly his own philosophy principally consists of the indirect abolition of these two antitheses. Yet partly to avoid injuring his teacher, partly in order to be less offensive, he gave it a positive appearance by means of a strictly dogmatic form, although its content is chiefly negative. His identification of the world with God has also this negative significance alone. For to call the world God is not to explain it: it remains a riddle under the one name as under the other. But these two negative truths had value for their age, as for every age in which there still are conscious or unconscious Cartesians.
