Famous quotes containing the word practical:
“I do not remember anything which Confucius has said directly respecting man’s “origin, purpose, and destiny.” He was more practical than that. He is full of wisdom applied to human relations,—to the private life,—the family,—government, etc. It is remarkable that, according to his own account, the sum and substance of his teaching is, as you know, to do as you would be done by.”
—Henry David Thoreau (1817–1862)
“Not many appreciate the ultimate power and potential usefulness of basic knowledge accumulated by obscure, unseen investigators who, in a lifetime of intensive study, may never see any practical use for their findings but who go on seeking answers to the unknown without thought of financial or practical gain.”
—Eugenie Clark (b. 1922)
