Page 45 - Were with his heart, and that was far away; He reck'd not of the life he lost nor prize, But where his rude hut by the Danube lay, There were his young barbarians all at play, There was their Dacian mother— he, their sire, Butcher'd to make a Roman holiday— All this rush'd with his blood— Shall he expire And unavenged? Arise! ye Goths, and glut your ire!
Page 45 - I see before me the Gladiator lie : He leans upon his hand — his manly brow Consents to death, but conquers agony, And his drooped head sinks gradually low — And through his side the last drops, ebbing slow From the red gash, fall heavy, one by one, Like the first of a thunder shower ; and now The arena swims around him : he is gone, Ere ceased the inhuman shout which hailed the wretch who won.

Page 52 - Leibnitz was the first, so far as I know, to call attention to the fact that words are sometimes more than signs of thought ; that they may become thoughts.
Page 269 - She works with a principle as true before she knows it to be so, because in watching how it operates upon facts consists the best means of establishing its truth ; but she must be prepared at the same time to abandon and dismiss it whenever it is found to be in direct and irreconcilable conflict with established facts.
Page 43 - ... involuntary gestures that indicate the feelings, even painting and sculpture, together with those contrivances which replace speech in situations where it cannot be employed, — the telegraph, the trumpet-call, the emblem, the hieroglyphic.* For the present, however, we may limit it to its most obvious signification ; it is a system of articulate words adopted by convention to represent outwardly the internal proofs of thinking.
