proof

A Quote by Mary Somerville on eternity, existence, mind, proof, science, and unity

Nothing has afforded me so convincing a proof of the unity of the Deity as these purely mental conceptions of numerical and mathematical science which have been by slow degrees vouchsafed to man, and are still granted in these latter times by the Differential Calculus, now superseded by the Higher Algebra, all of which must have existed in that sublimely omniscient Mind from eternity.

A Quote by Luis Vaz de Camões [Camoëns] on food and proof

in

The nut of this tree is hung high aloft, wrapped in a silk wrapper, which is enclosed in a case of sole leather, which again is packed in a mass of shock absorbing, vermin proof pulp, sealed up in a waterproof, ironwood case, and finally cased in a vegetable porcupine of spines, almost impregnable. There is no nut so protected; there is no nut in our woods to compare with it as food. What is a Chesnut?

A Quote by Thomas Babington, Lord Macaulay on age, genius, poetry, and proof

We hold that the most wonderful and splendid proof of genius is a great poem produced in a civilized age.

A Quote by John Dalberg, Lord Acton on accuracy, habits, history, learning, proof, theory, and writers

Writers the most learned, the most accurate in details, and the soundest in tendency, frequently fall into a habit which can neither be cured nor pardoned - the habit of making history into the proof of their theories.

A Quote by Karl Friedrich Gauss on doubt, impossibility, lawyers, and proof

I mean the word proof not in the sense of the lawyers, who set two half proofs equal to a whole one, but in the sense of a mathematician, where half proof = 0, and it is demanded for proof that every doubt becomes impossible.

A Quote by Kahlil Gibran on dreams, eternity, existence, knowledge, and proof

Each thing that exists remains forever, and that very existence of existence is proof of its eternity. But without that realization, which is the knowledge of perfect being, man would never know whether there was existence or non-existence. If eternal existence is altered, then it must become more beautiful; and if it disappears, it must return with more sublime image; and if it sleeps, it must dream of a better awakening, for it is ever greater upon its rebirth.

A Quote by Joseph Story on benevolence, charity, evil, exercise, forgiveness, good, heart, humility, imagination, judgment, learning, melancholy, men, mercy, persecution, pride, proof, purpose, religion, salvation, spirit, spirituality, teaching, vengean

How it is possible to imagine that a religion breathing the spirit of mercy and benevolence, teaching the forgiveness of injuries, the exercise of charity, and the return of good for evil, can be so perverted as to breathe the spirit of slaughter and persecution, of discord and vengeance, for differences of opinion, is a most unaccountable and extraordinary phenomenon. Still more extraordinary, that it should be the doctrine, not of base and wicked men merely seeking to cover up their own misdeeds, but of good men, seeking the way of salvation with uprightness of heart and purpose. It affords a melancholy proof of the infirmity of human judgment, and teaches a lesson of humility from which spiritual pride may learn meekness, and spiritual zeal a moderating wisdom.

A Quote by John Locke on certainty, doubt, existence, experience, intuition, knowledge, needs, pain, perception, pleasure, proof, reason, thinking, and thought

Our knowledge of our own existence is intuitive. As for our own existence, we perceive it so plainly and so certainly, that it neither needs nor is capable of any proof. . . . I think, I reason, I feel pleasure and pain: can any of these be more evident to me than my own existence? . . . For if I know I feel pain, it is evident I have as certain perception of my own existence, as of the existence of the pain I feel: or if I know I doubt, I have as certain perception of the existence of the thing doubting, as of that thought which I call doubt. Experience then convinces us, that we have an intuitive knowledge of our own existence, and an internal infallible perception that we are. In every act of sensation, reasoning, or thinking, we are conscious to ourselves of our own being; and, in this matter, come not short of the highest degree of certainty.

A Quote by John Kenneth Galbraith on choice, mind, needs, and proof

Faced with the choice between changing one's mind and proving there is no need to do so, almost everyone gets busy on the proof.
