Famous quotes containing the words ancient and/or times:
“The main foundations of every state, new states as well as ancient or composite ones, are good laws and good arms ... you cannot have good laws without good arms, and where there are good arms, good laws inevitably follow.”
—Niccolò Machiavelli (1469–1527)
“It seems to me that we do not know nearly enough about ourselves; that we do not often enough wonder if our lives, or some events and times in our lives, may not be analogues or metaphors or echoes of evolvements and happenings going on in other people?—or animals?—even forests or oceans or rocks?—in this world of ours or, even, in worlds or dimensions elsewhere.”
—Doris Lessing (b. 1919)
