“The last function of reason is to recognize that there are an infinity of things which surpass it.”

“Reason's last step is the recognition that there are an infinite number of things which are beyond it.”

“Man is equally incapable of seeing the nothingness from which he emerges and the infinity in which he is engulfed.”

“For after all what is man in nature? A nothing in relation to infinity, all in relation to nothing, a central point between nothing and all and infinitely far from understanding either. The ends of things and their beginnings are impregnably concealed from him in an impenetrable secret. He is equally incapable of seeing the nothingness out of which he was drawn and the infinite in which he is engulfed.”

“The heart has its reasons which reason knows not.”

“People are generally better persuaded by the reasons which they have themselves discovered than by those which have come into the mind of others.”

“The last thing one discovers in composing a work is what to put first.”
