There is no true love save in suffering, and in this world we have to choose either love, which is suffering, or happiness. Man is the more man - that is, the more divine - the greater his capacity for suffering, or rather, for anguish.

Yes, yes, I see it all! — an enormous social activity, a mighty civilization, a profuseness of science, of art, of industry, of morality, and afterwords, when we have filled the world with industrial marvels, with great factories, with roads, museums and libraries, we shall fall exhausted at the foot of it all, and it will subsist — for whom? Was man made for science or was science made for man?

Man is perishing. That may be, and if it is nothingness that awaits us let us so act that it will be an unjust fate.

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.

All knowledge has an ultimate goal. Knowledge for the sake of knowledge is, say what you will, nothing but a dismal begging of the question.
