If a philosopher is not a man, he is anything but a philosopher; he is above all a pedant, and a pedant is a caricature of a man.

The truth is that my work - I was going to say my mission - is to shatter the faith of men here, there, and everywhere, faith in affirmation, faith in negation, and faith in abstention in faith, and this for the sake of faith in faith itself; it is to war against all those who submit, whether it be to Catholicism, or to rationalism, or to agnosticism; it is to make all men live the life of inquietude and passionate desire.

Science is a cemetary of dead ideas.

It is truer to say that martyrs create faith more than faith creates martyrs.

Love personalizes all that it loves. Only by personalizing it can we fall in love with an idea.

Fear is the start of wisdom.

The mists remain of the false glory that erupts from history.
