Never preach a sermon without a text from the Bible, a text containing the theme which you can elaborate. The text is the best proof in support of your argument. A sermon without a text is an argument without a proof. (Isaac Mayer Wise)
Do not be fooled into believing that because a man is rich he is necessarily smart. There is ample proof to the contrary. View quote
Julius Rosenwald
In the first quarter of the nineteenth century the experimental proof for the interdependence of the composition and properties of chemical compounds resulted in the theory that they are mutually related, so that like composition governs like properties, and conversely. View quote
Wilhelm Ostwald
Fear is the opportunity for courage, not proof of cowardice. View quote
John McCain
The method of successive approximations is often applied to proving existence of solutions to various classes of functional equations; moreover, the proof of convergence of these approximations leans on the fact that the equation under study may be majorised by another equation of a simple kind. Similar proofs may be encountered in the theory of infinitely many simultaneous linear equations and in the theory of integral and differential equations. Consideration of semiordered spaces and operations between them enables us to easily develop a complete theory of such functional equations in abstract form. View quote
Leonid Kantorovich
Where the preamble declares, that coercion is a departure from the plan of the holy author of our religion, an amendment was proposed by inserting "Jesus Christ," so that it would read "A departure from the plan of Jesus Christ, the holy author of our religion;" the insertion was rejected by the great majority, in proof that they meant to comprehend, within the mantle of its protection, the Jew and the Gentile, the Christian and Mohammedan, the Hindoo and Infidel of every denomination.

Thomas Jefferson
Do not let habit, born from experience, force you along this road, directing aimless eye and echoing ear and tongue; but judge by reason the much contested proof which I have spoken. View quote
Parmenides
No single discovery from any of these fields denotes proof of evolution, but together they reveal that life evolved in a certain sequence by a particular process. View quote
Michael Shermer
People almost invariably arrive at their beliefs not on the basis of proof but on the basis of what they find attractive. View quote
Blaise Pascal
How was it that destruction could be so beautiful? Was there something in the scale of it? Was there some shadow in people, lusting for it? Or was it just a coincidental combination of the elements, the final proof that beauty has no moral dimension? View quote
Kim Stanley Robinson
Achievement of your happiness is the only moral purpose of your life, and that happiness, not pain or mindless self-indulgence, is the proof of your moral integrity, since it is the proof and the result of your loyalty to the achievement of your values. (Ayn Rand)
A quest for self-respect is proof of its lack. View quote
Ayn Rand
General ideas are no proof of the strength, but rather of the insufficiency of the human intellect. View quote
Alexis de Tocqueville
Don't despise empiric truth. Lots of things work in practice for which the laboratory has never found proof. View quote
Martin H. Fischer
You can never take too much care over the choice of your shoes. Too many women think that they are unimportant, but the real proof of an elegant woman is what is on her feet. View quote
Christian Dior
If English money was of the same value then as before, Hamburgh money must have risen in value. But where is the proof of this? View quote
David Ricardo
Difficulties are God's errands; and when we are sent upon them, we should esteem it a proof of God's confidence. View quote
Henry Ward Beecher
There is a sort of enthusiasm in all projectors, absolutely necessary for their affairs, which makes them proof against the most fatiguing delays, the most mortifying disappointments, the most shocking insults; and, what is severer than all, the presumptuous judgement of the ignorant upon their designs. View quote
Edmund Burke
The fact that the price must be paid is proof it is worth paying. View quote
Robert Jordan
Another roof, another proof. View quote
Paul Erdős
Few intellectual tyrannies can be more recalcitrant than the truths that everybody knows and nearly no one can defend with any decent data (for who needs proof of anything so obvious). And few intellectual activities can be more salutary than attempts to find out whether these rocks of ages might crumble at the slightest tap of an informational hammer. (Stephen Jay Gould)
That is why a criminal trial is not a search for truth. Scientists search for truth. Philosophers search for morality. A criminal trial searches for only one result: proof beyond a reasonable doubt. View quote
Alan Dershowitz
I am obliged to interpolate some remarks on a very difficult subject: proof and its importance in mathematics. All physicists, and a good many quite respectable mathematicians, are contemptuous about proof. I have heard Professor Eddington, for example, maintain that proof, as pure mathematicians understand it, is really quite uninteresting and unimportant, and that no one who is really certain that he has found something good should waste his time looking for proof.

G. H. Hardy
Think of Adam and Eve like an imaginary number, like the square root of minus one: you can never see any concrete proof that it exists, but if you include it in your equations, you can calculate all manner of things that couldn't be imagined without it. View quote
Philip Pullman
the only people who have proof of their sanity are those who have been discharged from mental institutions. View quote
