Page 45 - 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?

Names then are the means of fixing and recording the result of trains of thought, which without them must be repeated frequently, with all the pain of the first effort.* § 25. (iii.) Leibnitz was the first, so far as I know, to call attention to the fact that words are sometimes more than signs of thought...
Page 339 - Therefore earth differs from the others :" But the Vaiseshika stops us at the very first word, he does not admit the " Whatever," because it is not a " Whatever," but only one single case. It would be impossible to give instances, nay, to give a single instance for the Vyapti, proposed by the European Logicians, except earth over again. The third case is, where the Vyapti admits both of positive and negative instances, as in the hackneyed syllogism of the volcano. Here we can say, Wherever there...

Page 29 - Ulrici have since founded upon them. No : the man of science possesses principles, but the artist, not the less nobly gifted on that account, is possessed and carried away by them. " The principles which Art involves, science evolves. The truths on which the success of Art depends, lurk in the artist's mind in an undeveloped state,— guiding his hand, stimulating his invention, balancing his judgment, but not appearing in the form of enunciated propositions."* And because the artist cannot always...
