“You can't break a bad habit by throwing it out the window. You've got to walk it slowly down the stairs.”

“I never felt so fervently thankful, so soothed, so tranquil, so filled with the blessed peace, as I did yesterday when I learned that Michael Angelo was dead.”

“His head was an hour-glass; it could stow an idea, but it had to do it a grain at a time, not the whole idea at once.”

“It was Plato, according to Sosigenes, who set this as a problem for those concerned with these things, through what suppositions of uniform and ordered movements the appearances concerning the movements of the wandering heavenly bodies could be preserved.”

“I love to revel in philosophical matters-especially astronomy. I study astronomy more than any other foolishness there is. I am a perfect slave to it. I am at it all the time. I have got more smoked glass than clothes. I am as familiar with the stars as the comets are. I know all the facts and figures and have all the knowledge there is concerning them. I yelp astronomy like a sun-dog, and paw the constellations like Ursa Major.”

“No one can read the history of astronomy without perceiving that Copernicus, Newton, Laplace, are not new men, or a new kind of men, but that Thales, Anaximenes, Hipparchus, Empodocles, Aristorchus, Pythagorus, Oenipodes, had anticipated them.”

“What you can't imagine, you can't discover.”

“There's a world out there. Open a window, and it's there.”

“Truth is like a vast tree which yields more and more fruit the more you nurture it. The deeper the search in the mind of truth, the richer the discovery of the gems buried there.”
