Famous quotes containing the word difficult:
“A fact is a proposition of which the verification by an appeal to the primary sources of our knowledge or to experience is direct and simple. A theory, on the other hand, if true, has all the characteristics of a fact except that its verification is possible only by indirect, remote, and difficult means.”

“How difficult the task to quench the fire and the pride of private ambition, and to sacrifice ourselves and all our hopes and expectations to the public weal! How few have souls capable of so noble an undertaking! How often are the laurels worn by those who have had no share in earning them! But there is a future recompense of reward, to which the upright man looks, and which he will most assuredly obtain, provided he perseveres unto the end.”
—Abigail Adams (1744–1818)
“There is an ancient saying, which is a true one—”To fight against two opponents is a difficult thing.””
—Plato (c. 427–347 B.C.)
