"Mathematics alone make us feel the limits of our intelligence. For we can always suppose in the case of an experiment that it is inexplicable because we don't happen to have all the data. In mathematics we have all the data and yet we don't understand. We always come back to the contemplation of our human wretchedness. What force is in relation to our will, the impenetrable opacity of mathematics is in relation to our intelligence."
"When a man's life is destroyed or damaged by some wound or privation of soul or body, which is due to other men's actions or negligence, it is not only his sensibility that suffers but also his aspiration toward the good. Therefore there has been sacrilege towards that which is sacred in him."
