Proof Quotes - page 9

Comparatively few of the propositions and proofs in the Elements are his [Euclid's] own discoveries. In fact, the proof of the "Theorem of Pythagoras" is the only one directly ascribed to him. (Florian Cajori)
One can judge from experiment, or one can blindly accept authority. To the scientific mind, experimental proof is all important and theory is merely a convenience in description, to be junked when it no longer fits. To the academic mind, authority is everything and facts are junked when they do not fit theory laid down by authority. View quote
Robert A. Heinlein
I was just trying to show you,” he went on, "just how insubstantial a ‘common sense' idea can be when you pin it down. Neither ‘common sense' nor ‘logic' can prove anything. Proof comes from experiment, or to put it another way, from experience, and from nothing else. View quote
Robert A. Heinlein
Religious = absolute belief without proof. View quote
Robert A. Heinlein
The finest proof of our loyalty toward one another was our monstrous disloyalties towards everyone else. View quote
Alain de Botton
A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here. View quote
Francis Crick
Yes, a woman makes a fine weapon in capable hands...slim and supple as a sword blade...and a blade to which no man's armor is completely proof. View quote
Lin Carter
That God cannot lie, is no advantage to your argument, because it is no proof that priests can not, or that the Bible does not. View quote
Thomas Paine
Safeguarding national honour, without rancour but with firmness demanded by the circumstances, we have recovered the southern islands which are a legitimate part of our national territory. This decision was prompted by the need to put an end to the interminable seccession of evasive and dilatory tactics used by Great Britain to perpetuate its domination over the islands and their zone of influence. That evasive attitude was considered by the national government in the present circumstances as conclusive proof of Great Britain's lack of good will to begin serious negotiations without delay over the central question of the dispute and to recognize once and for all that their alleged rights stem from an act of seizure.

Leopoldo Galtieri
It lays down, as is generally known, that our speculations upon all subjects whatsoever, pass necessarily through three successive stages: a Theological stage, in which free play is given to spontaneous fictions admitting of no proof; the Metaphysical stage, characterized by the prevalence of personified abstractions or entities; lastly, the Positive stage, based upon an exact view of the real facts of the case.

Auguste Comte
A proof is a proof. What kind of a proof? It's a proof. A proof is a proof. And when you have a good proof, it's because it's proven. (Jean Chrétien)
Scars are medals branded on the flesh, and your enemies will be frightened by them because they are proof of your long experience of battle. View quote
Paulo Coelho
Faith is different from proof; the latter is human, the former is a Gift from God. View quote
Blaise Pascal
Unless you call attention to your presence who will know you're there? Even a country has to weave and wave a flag as proof of its existence. View quote
Rod McKuen
It's good when food tastes good, it's kind of like proof you're alive. View quote
Haruki Murakami
How nauseating in view of all this to see Fianna Fáil and the Progressive Democrats, the Taoiseach and the Tánaiste, reduce this to a game of scrabble... to a matter of finding the right words. We now know that Fianna Fáil ministers see nothing wrong with a Minister for Finance taking large amounts of money for personal use from business interests as long as there is no proof that any specific favours were done.

Joe Higgins
Similarities in the DNA code simply prove the same designer wrote the code. This is not evidence for evolution, it is actually proof for creation! View quote
Kent Hovind
Here was irrefutable proof that he was using the Holocaust to speak of the extermination of animal life. Doomed creatures that could not speak for themselves were being given the voice of a most articulate people who had been similarly doomed. He was seeing the tragic fate of animals through the tragic fate of Jews. The Holocaust as allegory. View quote
Yann Martel
There is a principle which is a bar against all information, which is proof against all arguments and which cannot fail to keep a man in everlasting ignorance - that principle is contempt prior to investigation. View quote
Herbert Spencer
This consideration must alter the form of our proposed inquiry; for the question being thus at least partly decided, since it is ascertained that we have rays of heat which give no light, it can only become a subject of inquiry whether some of these heat-making rays may not have a power of rendering objects visible, superadded to their now already established power of heating bodies. This being the case, it is evident that the onus probandi [burden of proof] ought to lie with those who are willing to establish such an hypothesis, for it does not appear that Nature is in the habit of using one and the same mechanism with any two of our senses. Witness the vibration of air that makes sound, the effluvia that occasion smells, the particles that produce taste, the resistance or repulsive powers that affect the touch-all these are evidently suited to their respective organs of sense.

William Herschel
After the first proof [of 'Sphere Spirals'] my high expectations were, as always, greatly disappointed. I am now struggling on - with some feeling of despair - so that I at least achieve a passable result. (M. C. Escher)
As far as I know, there is no proof whatever of the existence of an objective reality apart from our senses, and I do not see why we should accept the outside world as such solely by virtue of our senses. View quote
M. C. Escher
He who has laughter on his side has no need of proof. View quote
Theodor Adorno
It is good proof of Keynes' intuitive genius that he reaches practical results that in many respects are very much superior to his deficient statements of certain theoretical problems. View quote
Gunnar Myrdal
Well, at first I thought it was a very inappropriate question, you know, for the presidency to be decided on a scientific matter. And uh, I um, I think it's a theory - the theory of evolution. And I don't accept it, you know, as a theory. But it really doesn't bother me, it's not the most important issue for me, to make the difference in my life, to understand the exact origin. I think the creator that I know, uh, you know created us, every one of us and created the universe, and the precise time and manner and uh, you know, I just don't think we're at the point where anybody has absolute proof on either side.
