A Quote by George Bernard Shaw on assumptions and belief

What a man believes may be ascertained, not from his creed, but from the assumptions on which he habitually acts.

A Quote by Frank Hyneman Knight on absence, assumptions, change, consequences, economics, problems, revolution, and struggle

If all properly economic problems were solved once for all . . . the social struggle and strife would . . . [not necessarily] be reduced in amount or intensity . . . in the absence of some moral revolution which could by no means be assumed to follow in consequence of this change itself.

A Quote by Sir Francis Bacon on assumptions, caring, company, difficulty, earth, nature, and separation

Over a century after the publication of the Copernican system, one of England's most renowned intellectual luminaries was still unconvinced: "Nevertheless, in the system of Copernicus there are found many and great inconveniences; for both the loading of the earth with a triple motion is very incommodious, and the separation of the sun from the company of the planets, with which it has so many passions in common, is likewise a difficulty, and the introduction of so much immobility in nature, by representing the sun and stars as immovable, especially being of all bodies the highest and most radiant, and making the moon revolve about the earth in an epicycle, and some other assumptions of his, are the speculations of one who cares not what fictions he introduces into nature, provided his calculations answer."

A Quote by Father Jeremiah Joseph Callahan on assumptions, difficulty, mind, schools, theory, thought, and path

Einstein is an analytical mathematician seeking to give a physical interpretation to the conclusions of his mathematical process. In this he is hampered by a load of contradictory and absurd assumptions of the school that he follows, which throws him in to all manner of difficulty. Einstein has such a faculty for embracing both sides of a contradiction that one would have to be of the same frame of mind to follow his thought, it is so peculiarly his own. The whole Relativity theory is as easy to follow as the path of a bat in the air at night.

A Quote by Eric Temple Bell on argument, assumptions, and proof

Euclid taught me that without assumptions there is no proof. Therefore, in any argument, examine the assumptions.

A Quote by Eric G. Anderson on assumptions, christmas, dedication, duty, failure, fear, leadership, learning, life, limits, obligation, responsibility, schools, seriousness, sports, strength, present, and trust

Climbing is a unique sport, presenting mental and physical stress that you learn to overcome by operating close to your limits. Sometimes your limits are higher than you realize. "Of course, you recognize your limits in climbing by falling off the rock," says Alan Czenkusch [leader of Whistepig Climbing School of Del Norte, Colorado]. "However, you're safe because you're on belay." The belay anchor system is the crux of climbing. It allows falls with impunity - almost. The person running the rope does so to protect the climber. There is a great responsibility and obligation to this concept and Czenkusch explains it solemnly. The belayer protects himself by the use of pitons and other devices which give him fail-safe redundant protection. When the belayer calls out to the climber below "On Belay" it means he is set up correctly and has assumed a serious duty and would even give up his own life to protect the climber. Such dedication should allow the person below to ascent with no fear of falling. The mutual trust which allows belaying is part of the camaraderie, the intimacy, the mystique of mountaineering. Belaying has brought Czenkusch his best and worst moments in climbing. Czenkusch once fell from a high precipice, yanking out three mechanical supports and pulling his belayer off a ledge. He was stopped upside down 10 feet from the ground when his spread-eagled belayer arrested the fall with the strength of his outstretched arms. "Don saved my life," says Czenkusch. "How do you respond to a guy like that? Give him a used climbing rope for a Christmas present? No, you remember him. You always remember him."

A Quote by Elliot D. Landau on assumptions and world

In this very material world where the acquisition of things assumes an importance that too often overshadows the pursuit of everything else, it is too easy for families to pursue other gods.

A Quote by Dorothy Parker on assumptions

If, with the literate, I am Impelled to try an epigram, I never seek to take the credit; We all assume that Oscar said it.

A Quote by Donald M. Nelson on acceptance, assumptions, beginning, change, habits, ideas, and past

We must drop the idea that change comes slowly. It does ordinarily - in part because we think it does. Today changes must come fast; and we must adjust our mental habits, so that we can accept comfortably the idea of stopping one thing and beginning another overnight. We must discard the idea that past routine, past ways of doing things, are probably the best ways. On the contrary, we must assume that there is probably a better way to do almost everything. We must stop assuming that a thing which has never been done before probably cannot be done at all.
