Principle never forgives and its logic is to kill.

You can only find truth with logic if you have already found truth without it.

In the end, we are all the sum total of our actions. Character cannot be counterfeited, nor can it be put on and cast off as if it were a garment to meet the whim of the moment. Like the markings on wood which are ingrained in the very heart of the tree, character requires time and nurture for growth and development. Thus also, day by day, we write our own destiny; for inexorably we become what we do. This I believe, is the supreme logic and the law of life.

A treaty, in the minds of our people, is an eternal word. Events often make it seem expedient to depart from the pledged word, but we are conscious that the first departure creates a logic for the second departure, until there is nothing left of the word.

He who recognizes no higher logic than that of the shilling may become a very rich man, and yet remain a very poor creature, for riches are no proof of moral worth, and their glitter often serves only to draw attention to the worthlessness of their possessor, as the glowworm's light reveals the grub.

A land ethic for tomorrow should be as honest as Thoreau's Walden, and as comprehensive as the sensitive science of ecology. It should stress the oneness of our resources and the live-and-help-live logic of the great chain of life. If, in our haste to "progress," the economics of ecology are disregarded by citizens and policy makers alike, the result will be an ugly America.

The humorous man recognizes that absolute purity, absolute justice, absolute logic and perfection are beyond human achievement and that men have been able to live happily for thousands of years in a state of genial frailty.

Humor (is) something that thrives between man's aspirations and his limitations. There is more logic in humor than in anything else. Because, you see, humor is truth.

Most mistakes in philosophy and logic occur because the human mind is apt to take the symbol for the reality.

Capitalism inevitably and by virtue of the very logic of its civilization creates, educates and subsidizes a vested interest in social unrest.

Languages are spiritual organisms, vital works of art, each of them having its measure of creative power, splendor, depth, logic to explore and to construct the world of nature in life.

A mind all logic is like a knife all blade. It makes the hand bleed that uses it.

A religion without mystery must be a religion without God. In dwelling on divine mysteries, keep thy heart humble, thy thoughts reverent, thy soul holy. Let not philosophy be ashamed to be confuted, nor logic to be confounded, nor reason to be surpassed. What thou canst not prove, approve; what thou canst not comprehend, believe; what thou canst believe, admire and love and obey. so shall thine ignorance be satisfied in thy faith, and thy doubt be swallowed up in thy reverence, and thy faith be as influential as sight. Put out thing own candle, and then shalt thou see clearly the sun of righteousness.

Music being the universal expression of the mysterious and supernatural, the best that man has ever attained to, is capable of uniting in common devotion minds that are only separated by creeds, and it comforts our hope with a brighter promise of unity than any logic offers.

You can only find truth with logic if you have already found truth without it.

Poetry transcends logic as the spiritual transcends the physical and intellectual. It reveals life eternally and the instruments of time are too mean to record its mystery.

Are you open to the full interrogation of life? Or are you close to the search because you believe what you’ve always believed without question? Have you pondered the logic of your experiences and dared to follow the direction of their limits and promptings?

Philosophy is only a matter of passionate vision rather than of logic - logic only finding reasons for the vision afterwards.

Beliefs and convictions reach out from the past, and they cannot be altered by fervent desire alone. They possess their own logic and illogic, their own organic existence, their own rhythm of development.

It is certain that the two World Wars in which I have participated would not have occurred had we been prepared. It is my belief that adequate preparation on our part would have prevented or materially shortened all our other wars beginning with that of 1812. Yet, after each of our wars, there has always been a great hue and cry to the effect that there will be no more wars, that disarmament is the sure road to health, happiness, and peace; and that by removing the fire department, we will remove fires. These ideas spring from wishful thinking and from the erroneous belief that wars result from logical processes. There is no logic in wars. They are produced by madmen. No man can say when future madmen will reappear. I do not say that there will be no more wars; I devoutly hope that there will not, but I do say that the chances of avoiding future wars will be greatly enhanced if we are ready.
