Famous quotes containing the words experimental and/or subject:
“When we run over libraries persuaded of these principles, what havoc must we make? If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames; for it can contain nothing but sophistry and illusion.”
—David Hume (1711–1776)
“In a pure society, the subject of marriage would not be so often avoided,—from shame and not from reverence, winked out of sight, and hinted at only; but treated naturally and simply,—perhaps simply avoided like the kindred mysteries. If it cannot be spoken of for shame, how can it be acted of? But, doubtless, there is far more purity, as well as more impurity, than is apparent.”
—Henry David Thoreau (1817–1862)
