The particular suggestions to which these remarks were the characteristic introduction related to definite problems of education, that is to say, to questions upon which some action was urgent. It was in all cases of life, in science or affairs, that Huxley was resolute for clear ideas and definite courses of conduct. As a matter of fact, no one ever took greater care to satisfy himself as best he could as to what was right and what was wrong; but where action rather than reflection was needed, then his principle was to act, and to know definitely and clearly why you acted and for what you acted. In matters of opinion, on the other hand, he was all for not coming to a definite opinion when the facts obtainable did not justify such an opinion. In thought, agnosticism, the refusal to accept any ideas or principles except on sufficient evidence; in action, positivism, to act promptly in definite and known directions for definite and known objects: these were his principles. Another aspect of the same trait of character, he shewed in an address to medical students at a distribution of prizes. After congratulating the victors he confessed to "an undercurrent of sympathy for those who have not been successful, for those valiant knights who have been overthrown in their tourney, and have not made their appearance in public." After recounting an early failure of his own, he proceeded: "I said to myself, 'Never mind; what's the next thing to be done?' And I found that policy of 'never minding' and going on to the next thing to be done, to be the most important of all policies in the conduct of practical life. It does not matter how many tumbles you have in this life, so long as you do not get dirty when you tumble; it is only the people who have to stop to be washed and made clean, who must necessarily lose the race. You learn that which is of inestimable importance--that there are a great many people in the world who are just as clever as you are. You learn to put your trust, by and by, in an economy and frugality of the exercise of your powers both moral and intellectual; and you very soon find out, if you have not found it out before, that patience and tenacity of purpose are worth more than twice their weight of cleverness."
