Famous quotes containing the words necessity and/or sufficiency:
“He says a man may perhaps answer, that the necessity of things held by him, is not a stoical necessity, but a Christian necessity, &c. But this distinction I have not used, nor indeed have ever heard before, nor could I think any man could make stoical and Christian two kinds of necessity, though they may be two kinds of doctrine”
—Thomas Hobbes (1579–1688)
“The worthiest man to be known, and for a pattern to be presented to the world, he is the man of whom we have most certain knowledge. He hath been declared and enlightened by the most clear-seeing men that ever were; the testimonies we have of him are in faithfulness and sufficiency most admirable.”
—Michel de Montaigne (1533–1592)
