But why? What need for the soldier and the man of science to fraternise just now? This need: the two classes which will have an increasing, it may be a preponderating, influence on the fate of the human race for some time, will be the pupils of Aristotle and those of Alexander--the men of science and the soldiers. In spite of all appearances, and all declamations to the contrary, that is my firm conviction. They, and they alone, will be left to rule; because they alone, each in his own sphere, have learnt to obey. It is therefore most needful for the welfare of society that they should pull with, and not against each other; that they should understand each other, respect each other, take counsel with each other, supplement each other's defects, bring out each other's higher tendencies, counteract each other's lower ones. The scientific man has something to learn of you, gentlemen, which I doubt not that he will learn in good time. You, again, have--as I have been hinting to you to-night--something to learn of him, which you, I doubt not, will learn in good time likewise. Repeat, each of you according to his powers, the old friendship between Aristotle and Alexander; and so, from your mutual sympathy and co-operation, a class of thinkers and actors may yet arise which can save this nation, and the other civilised nations of the world, from that of which I had rather not speak, and wish that I did not think too often and too earnestly. I may be a dreamer; and I may consider, in my turn, as wilder dreamers than myself, certain persons who fancy that their only business in life is to make money, the scientific man's only business is to show them how to make money, and the soldier's only business to guard their money for them. Be that as it may, the finest type of civilised man which we are likely to see for some generations to come, will be produced by a combination of the truly military with the truly scientific man. I say--I may be a dreamer; but you at least, as well as my scientific friends, will bear with me; for my dream is to your honour. SUPERSTITION {201} Having accepted the very great honour of being allowed to deliver here two lectures, I have chosen as my subject Superstition and Science. It is with Superstition that this first lecture will deal. The subject seems to me especially fit for a clergyman; for he should, more than other men, be able to avoid trenching on two subjects rightly excluded from this Institution; namely, Theology-- that is, the knowledge of God; and Religion--that is, the knowledge of Duty. If he knows, as he should, what is Theology, and what is Religion, then he should best know what is not Theology, and what is not Religion.
