Famous quotes containing the word probable:
“It is the mark of an educated man to look for precision in each class of things just so far as the nature of the subject admits; it is evidently equally foolish to accept probable reasoning from a mathematician and to demand from a rhetorician demonstrative proofs.”
—Aristotle (384–323 B.C.)
“It makes me hate accepting things that are probable when they are held up before me as infallibly true. I prefer these words which tone down and modify the hastiness of our propositions: “Perhaps, In some sort, Some, They say, I think,” and the like.”
—Michel de Montaigne (1533–1592)
