In the reproach that Hegel will make to Spinoza, that he ignored the negative and its power, lies the glory and innocence of Spinoza, his own discovery. In a world consumed by the negative, he has enough confidence in life, in the power of life, to challenge death, the murderous appetite of men, the rules of good and evil, of the just and the unjust. Enough confidence in life to denounce all the phantoms of the negative.
For Spinoza is one of the vivants-voyants. Spinoza did not believe in hope or even in courage; he believed only in joy, and in vision. He let others live, provided that others let him live. He wanted only to inspire, to waken, to reveal.
