Our duty, as men and women, is to proceed as if limits to our ability did not exist. We are collaborators in creation.

It is our duty as men and women to proceed as though the limits of our abilities do not exist.

To show your true ability is always, in a sense, to surpass the limits of your ability, to go a little beyond them: to dare, to seek, to invent; it is at such a moment that new talents are revealed, discovered, and realized.

A Religion of Evolution: that, when all is said and done, is what Man needs ever more explicitly if he is to survive and 'superlive,' as soon as he becomes conscious of his power to ultra-hominize himself and of his duty to do so.

I think that man has a fundamental obligation to extract from himself and from the earth all that it can give; and this obligation is all the more imperative that we are absolutely ignorant of what limits - they may still be very distant - God has imposed on our natural understanding and power.

How can one preach goodness and love to men without at the same time offering them an interpretation of the World that justifies this goodness and this love?
