Knowledge must come through action; you can have no test which is not fanciful, save by trial.

Line 592.Sophocles
I am not attempting here a full appreciation of Colonel Roosevelt. He will be known for all time as one of the great men of America. I am only giving you this personal recollection as a little contribution to his memory, as one that I can make from personal knowledge and which is now known only to myself. His conversation about birds was made interesting by quotations from poets. He talked also about politics, and in the whole of his conversation about them there was nothing but the motive of public spirit and patriotism. I saw enough of him to know that to be with him was to be stimulated in the best sense of the word for the work of life. Perhaps it is not yet realised how great he was in the matter of knowledge as well as in action. Everybody knows that he was a great man of action in the fullest sense of the word. The Press has always proclaimed that. It is less often that a tribute is paid to him as a man of knowledge as well as a man of action. Two of your greatest experts in natural history told me the other day that Colonel Roosevelt could, in that department of knowledge, hold his own with experts. His knowledge of literature was also very great, and it was knowledge of the best. It is seldom that you find so great a man of action who was also a man of such wide and accurate knowledge. I happened to be impressed by his knowledge of natural history and literature and to have had first-hand evidence of both, but I gather from others that there were other fields of knowledge in which he was also remarkable.
Edward Grey
The end of man is knowledge but there's one thing he can't know. He can't know whether knowledge will save him or kill him. He will be killed, all right, but he can't know whether he is killed because of the knowledge which he has got or because of the knowledge which he hasn't got and which if he had it would save him.
Robert Penn Warren
Knowledge alone is not power, knowledge plus action equals power. Knowledge is useless without action and vice versa.
Lupe Fiasco
Knowledge is theory. We should be thankful if action of management is based on theory. Knowledge has temporal spread. Information is not knowledge. The world is drowning in information but is slow in acquisition of knowledge. There is no substitute for knowledge.
W. Edwards Deming
It appears that mankind in this life are not agents of trial for eternity, but that they will eternally remain agents of trial. To suppose that our eternal circumstances will be unalterably fixed in happiness or misery, in consequence of the agency or transactions of this temporary life, is inconsistent with the moral government of God, and the progressive and retrospective knowledge of the human mind. God has not put it into our power to plunge ourselves into eternal woe and perdition; human liberty is not so extensive, for the term of human life bears no proportion to eternity succeeding it; so that there could be no proportion between a momentary agency, (which is liberty of action,) or probation, and any supposed eternal consequences of happiness or misery resulting from it.
