What is absolute certainty? Where is it to be found? Does it exist? Is there any belief of mankind which can be claimed as absolutely certain?
It is difficult to define an absolute in any kind. One can only say that the absolute is that which wants [needs] nothing to make it complete. The absolute does not even want a philosopher to tell the world what the absolute is. So long as it wants a philosopher to expound it, to that extent it is not complete, and is therefore not the absolute.
Spinoza saw this, and made it the corner-stone of his thought. He saw that Perfection must be capable of telling its own story. It cannot at one and the same time be perfect and yet in need of a human spokesman to explain it. A dumb absolute which needs you to give it a tongue, an unintelligible absolute which needs you to make it rational, a dead absolute which needs you to make it live and interesting, would be no absolute at all. So Spinoza begins his great treatise with admirable humility by defining God as the being who defines himself; who, just because he is all-perfect, needs no explainer, being fully competent to explain himself. God asks for no champions; wants no apologist; seeks for no witnesses. If he did, he would not be God. But Spinoza went too far.
