Perfection is such a nuisance that I often regret having cured myself of using tobacco.

Civilization will not attain to its perfection until the last stone from the last church falls on the last priest

I am little concerned with beauty or perfection. I don't care for the great centuries. All I care about is life, struggle, intensity.

I will never regret not denouncing apartheid.

I believe that the future of humanity is in the progress of reason through science. I believe that the pursuit of truth, through science, is the divine ideal which man should propose to himself.

If I cannot overwhelm with my quality, I will overwhelm with my quantity.
