“I can no longer sit back and allow Communist infiltration, Communist indoctrination, Communist subversion and the international Communist conspiracy to sap and impurify all of our precious bodily fluids.—Brigadier General Jack D. Ripper”

“All work and no play makes Jack a dull boy.”

“The most terrifying fact about the universe is not that it is hostile but that it is indifferent, but if we can come to terms with this indifference, then our existence as a species can have genuine meaning. However vast the darkness, we must supply our own light.”

“You sit at the board and suddenly your heart leaps. Your hand trembles to pick up the piece and move it. But what chess teaches you is that you must sit there calmly and think about whether it's really a good idea and whether there are other, better ideas.”

“If man merely sat back and thought about his impending termination, and his terrifying insignificance and aloneness in the cosmos, he would surely go mad, or succumb to a numbing sense of futility. Why, he might ask himself, should he bother to write a great symphony, or strive to make a living, or even to love another, when he is no more than a momentary microbe on a dust mote whirling through the unimaginable immensity of space? Those of us who are forced by their own sensibilities to view their lives in this perspective — who recognize that there is no purpose they can comprehend and that amidst a countless myriad of stars their existence goes unknown and unchronicled — can fall prey all too easily to the ultimate anomie. The world's religions, for all their parochialism, did supply a kind of consolation for this great ache.”

“I’ve never been certain whether the moral of the Icarus story should only be, as is generally accepted, ‘don’t try to fly too high,’ or whether it might also be thought of as ‘forget the wax and feathers, and do a better job on the wings.”

“The very meaninglessness of life forces man to create his own meaning. Children, of course, begin life with an untarnished sense of wonder, a capacity to experience total joy at something as simple as the greenness of a leaf; but as they grow older, the awareness of death and decay begins to impinge on their consciousness and subtly erode their joie de vivre, their idealism – and their assumption of immortality. As a child matures, he sees death and pain everywhere about him, and begins to lose faith in the ultimate goodness of man. But, if he’s reasonably strong – and lucky – he can emerge from this twilight of the soul into a rebirth of life’s elan. Both because of and in spite of his awareness of the meaninglessness of life, he can forge a fresh sense of purpose and affirmation. He may not recapture the same pure sense of wonder he was born with, but he can shape something far more enduring and sustaining. The most terrifying fact about the universe is not that it is hostile but that it is indifferent; but if we can come to terms with this indifference and accept the challenges of life within the boundaries of death – however mutable man may be able to make them – our existence as a species can have genuine meaning and fulfillment. However vast the darkness, we must supply our own light.”
