"Sigmund Freud often remarked that great revolutions in the history of science have but one common, and ironic, feature: they knock human arrogance off one pedestal after another of our previous conviction about our own self-importance. The first that we associate with Copernicus, Newton, and Galileo that taught us that we weren't living on the central body of a limited universe. And that Darwin's was the second that taught us that we were not separately created in the image of a benevolent deity, but were part of a history of genealogical connectivity of all living things. Now, in an odd sense, we know how contentious the first revolution was; we know the story of Galileo.
But the way I like to put it, I don't think that revolution was as important as Darwin's, because it's about real estate. The Darwinian revolution is about essence; it's deeper. The Darwinian revolution is about who we are, it's what we're made of, it's what our life means insofar as science can answer that question. "
Stephen Jay Gould
"The importance of the Scientific Revolution for philosophy is beyond question. Modern philosophy the work of both rationalists and empiricists would have been impossible without great advances in physics. Analogously, therefore, we could anticipate that the Darwinian Revolution will have important implications for philosophy. Indeed, I would go further and say that we might expect Darwin's work to have even greater implications for philosophy than those of physics. The theory of evolution through natural selection impinges so directly on our own species. It is not just that we are on a speck of dust whirling around in the void but that we ourselves are no more than transformed apes. If such a realization is not to affect our views of epistemology and ethics, I do not know what is. As I said in the Preface, I find it inconceivable that it is irrelevant to the foundations of philosophy whether we are the end result of a slow natural evolutionary process, or made miraculously in Gods own image on a Friday, some 6,000 years ago.

Carl Sagan stated, "we make our world significant by the courage of our questions and the depth of our answers" and "We live on a hunk of rock and metal that circles a humdrum star that is one of 400 billion other stars that make up the Milky Way Galaxy which is one of billions of other galaxies which make up a universe which may be one of a very large number, perhaps an infinite number, of other universes. That is a perspective on human life and our culture that is well worth pondering."
"I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding of a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me."
Sir Isaac Newton (1642-1727) English physicist, mathematician.
