"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." - Madame Chiang Kai-Shek, born Soong Mei-ling or May-ling

"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." - Samuel Smiles

"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." - Stewart Udall, Fully Stewart Lee Udall

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

"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." - Nachman Syrkin

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

"Things are distinct not in their essence but in their appearance; in other words, in their relation to one to whom they appear. This is art, the truth of which is not in substance or logic, but in expression. Abstract truth may belong to science and metaphysics, but the world of reality belongs to art." -

"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." - Jeremy Taylor

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

"There must be for me a deep sense of relatedness to God. This relatedness is the way by which there shall open for me more and more springs of energy and power, which will enable me to thread life’s mysteries with life’s clue.

"Logic [knowledge] will get you from A to B. Imagination will take you everywhere." - Albert Einstein

"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." -

"One of the most ordinary weakness of the human intellect is to seek reconcile contrary principles, and to purchase peace at the expense of logic." - Alexis de Tocqueville, Alexis-Charles-Henri Clérel de Tocqueville

"All beliefs are demonstrably true. All men are demonstrably in the right. Anything can be demonstrated by logic." - Antoine de Saint-Exupery

"Man’s dwelling place, who could found you on reasoning, or build your walls with logic? You exist, and you exist not. You are, and are not. True, you are made out of diverse materials, but for your discovery an inventive mind was needed. Thus if a man pulled his house to pieces, with the design of understanding it, all he would have before him would be heaps of bricks and stones and tiles. he would not be able to discover therein the silence, the shadows and the privacy they bestowed. Nor would he see what service this mass of bricks, stones and tiles could render him, now that they lacked the heart and soul of the architect, the inventive mind which dominated them. For in mere stone the heart and soul of man have no place. But since reasoning can deal with only such material things as bricks and stones and tiles, and there is no reasoning about the heart and soul that dominate them and thus transform them into silence - inasmuch as the heart and soul have no concern with the rules of logic or the science of numbers - this is where I step in and impose my will. I, the architect; I, who have a heart and soul; I, who wield the power of transforming stone into silence. I step in and mold that clay, which is the raw material, into the likeness of the creative vision that comes to me from God; and not through any faculty of reason. Thus, taken solely by the savor it will have, I build my civilization; as poets build their poems, bending phrases to their will and changing words, without being called upon to justify the phrasing of the changes, but taken solely by the savor these will have, vouched by their hearts." - Antoine de Saint-Exupery

"Few persons care to study logic, because everybody conceives himself to be proficient enough in the art of reasoning already. But I observe that this satisfaction is limited to one’s own ratiocination, and does not extend to that of other men." -

"When dealing with people remember you are not dealing with creatures of logic, but with creatures of emotion, creatures bristling with prejudice, and motivated by pride and vanity." - Dale Carnegie, originally spelled Dale Carnegey

"Reading maketh a full man; conference a ready man; histories make men wise; poets, witty; the mathematics, subtle; natural philosophy, deep; moral philosophy, grace; logic and rhetoric, able to contend." - Francis Bacon

"Science does not have appropriate tools for the dissection of the spirit. How sad it would be, I thought, if we humans ultimately were to lose all sense of mystery, all sense of awe, if our left brains were utterly to dominate the right so that logic and reason triumphed over intuition and alienated us absolutely from our innermost being, from our hearts, from our souls." - Jane Goodall, fully Dame Jane Morris Goodall, born Valerie Jane Morris-Goodall

"Logic and cold reason are poor weapons to fight fear and distrust. Only faith and generosity can overcome them." - Jawaharlal Nehru

"The world is a single whole. Everything is linked with everything else. The world 'sounds'. It is a 'chord'. The imagination and freedom necessary for feeling, experiencing, and living through - rather than merely knowing - these are more likely to be associated with an ana-logical process of perception than with logical thinking. Logic aims at security. The ana-logician has the courage to embark on risk and adventure. Logic is goal-oriented and passes judgment. Analogy ponders and establishes relationships. The logician sees. The ana-logician listens... The eye glimpses surfaces and is attached to them, always remaining superficial (on the surface). The ear penetrates deep into the realms it investigates through hearing." - Joachim-Ernst Berendt

"Logic, which alone can give certainty, is the instrument of demonstration; intuition is the instrument of invention." - Henri Poincaré, fully Jules Henri Poincaré

"Against logic there is no armor like ignorance." - Laurence J. Peter, fully Laurence Johnston Peter
