Do we ever think without knowing that we are thinking? Leibnitz long ago said yes. We remember a name by ceasing the conscious search for it. One goes to sleep with a problem in mind, and awakens with the solution clear. The man of genius is inspired he knows not how: the deepest things are not in the consciousness. How Burns composed his poems. An idea planted in a thinker's mind will grow when he is least conscious of growth. 95 MAUDSLEY, HENRY MEMORY. Unless the mind retains impressions and can recall them, no development is possible. Acts at first difficult become easy because nerves and muscles remember. Attention is the mother of memory. The more various and intimate the association of ideas the better. 115 CARPENTER, WILLIAM B. COMMON SENSE. Walking and other common movements of the body become all but automatic. In much the same way mental experiences become organized into judgments which are largely or wholly true. Judgment in mathematics or other sciences demands special training. Grammar is often unconsciously acquired. The intuitions of the practised detective. The desire to do right strengthens the intellect. A wise man trusts to the spontaneities of his mind, just as a rider may trust his horse to find its way home. The human race, like the individual man, grows in common sense, abandons absurd practices and beliefs. 131 HUXLEY, THOMAS H. A LIBERAL EDUCATION. If we are to win the game of life we must understand and obey its rules. No man wholly uneducated. A liberal education makes the most of body, mind and heart. Education to the poor is of supreme importance: reading and writing are merely the means of education. The classics should be taught in a scientific way. Thorough knowledge of the earth as a centre from which study may proceed. Literature and history are indispensable. 151 HUXLEY, THOMAS H. SCIENCE AND CULTURE.
