It is an amazing thing that our memory best retains images of great philosophers when their lives were coming to an end. Socrates raising the chalice… - Benedictus de Spinoza

I believe that the absolute point of view which Spinoza has so impressively, so overpoweringly enforced cannot be avoided; it is the ocean in which every stream of thought is lost; and for that very reason Spinoza's apparent optimism seems to be deceptive.

...Now Spinoza, my master and model in respect to the first point [the natural basis of morality], does not satisfy me on the second [the humane possibilities, the "types of excellence towards which life may be directed"]; and I will take this opportunity, since I may not have any other, of clearing my conscience of ambiguity in that respect. The complete moralist must not only be sound in physics, but must be inwardly inspired by a normal human soul and an adequate human tradition; he must be a complete humanist in a complete naturalist. Spinoza was not only a complete naturalist but, by a rare combination, also a spiritual man, seeing and accepting the place of the human heart in the universe; accepting it not grudgingly or viciously or frivolously, as your worldling does, but humbly and joyously: humbly in that he asked to be nothing more than he was, and joyously because what he was allowed him, in spirit, to salute and to worship every form of the good. Nevertheless, Spinoza was not a complete humanist. He had no idea of human greatness and no sympathy with human sorrow. His notion of the soul was too plebeian and too quietistic. He was a Jew not of Exodus or Kings but of Amsterdam. He was too Dutch, too much the merchant and artisan, with nothing of the soldier, the poet, the prince, or the lover. [...] He was virtuous but not normal. [...] He was a genius; but as a guide in the spiritual life, he was narrow and inadequate.

Spinoza redefines the problem of Modern philosophy, which is the conquest of the world and the liberation of humanity, and destroys both its multiple antinomies and the continually resurgent separation (dualistic, transcendental, etc.) in the theory of knowledge and history, in the same way that criticism has always destroyed Zenonian sophism: moving forward, putting reality in motion. Spinoza's philosophy is born from the radicalization of the ontological paradox of being: in the recognition that the hypostasis, the only possible hypostasis, is that of the world and of the development of its necessity from physics to practice. It is a conception of the world that immediately produces, as if from its own basis, a completely modern conception of science and worldly knowledge, both technical and liberatory. It is a radically materialistic conception of being and of the world.
