Famous quotes containing the word actions:
“From a purely external point of view there is no will; and to find will in any phenomenon requires a certain empathy; we observe a man’s actions and place ourselves partly but not wholly in his position; or we act, and place ourselves partly in the position of an outsider.”
—T.S. (Thomas Stearns)
“History by apprising them [students] of the past will enable them to judge of the future; it will avail them of the experience of other times and other nations; it will qualify them as judges of the actions and designs of men; it will enable them to know ambition under every disguise it may assume; and knowing it, to defeat its views.”
—Thomas Jefferson (1743–1826)
“Hence a young man is not a proper hearer of lectures on political science; for he is inexperienced in the actions that occur in life, but its discussions start from these and are about these; and, further, since he tends to follow his passions, his study will be vain and unprofitable, because the end aimed at is not knowledge but action.”
—Aristotle (384–322 B.C.)
