Famous quotes containing the words effect on, effect and/or yield:
“Power is poison. Its effect on Presidents had always been tragic.”
—Henry Brooks Adams (1838–1918)
“Even a purely moral act that has no hope of any immediate and visible political effect can gradually and indirectly, over time, gain in political significance.”
—Václav Havel (b. 1936)
“Quarrel not at all. No man resolved to make the most of himself, can spare time for personal contention. Still less can he afford to take all the consequences, including the vitiating of his temper, and the loss of self-control. Yield larger things to which you can show no more than equal right; and yield lesser ones, though clearly your own. Better give your path to a dog, than be bitten by him in contesting for the right. Even killing the dog would not cure the bite.”
—Abraham Lincoln (1809–1865)
