“It is by no means certain that we advance our philosophical quest by reading Plato or Aristotle. It may increase our knowledge of history but not of the world.”

“If we commit ourselves to reading thus increasing our knowledge, only God limits how far we can go in this world.”

“Plato and Aristotle.....survived to become the twin pillars of philosophic and scientific thinking in the Western world, supporting the massive edifice of Christianity. Plato's Theory of Forms, with it's inherent contempt for the physical world, and Aristotle's biological dualism, in which females were seen as failed males, provided the intellectual apparatus for the centuries of misogyny that were to follow.”

“In that case, on behalf of Earthlife, I urge that, with full knowledge of our limitations, we vastly increase our knowledge of the Solar System and then begin to settle other worlds.”

“The chief purpose of life, for any of us, is to increase according to our capacity our knowledge of God by all means we have, and to be moved by it to praise and thanks.”

“Our weapon is our knowledge. But remember, it may be a knowledge we may not know that we possess.”
