, BELIEFS subjective and illusory. But it should be remembered that, to those who have never actually had it, any direct intuition must seem subjective and illusory. It is impossible for the deaf to form any idea of the nature or significance of music. Nor is physical disability the only obstacle in the way of musical understanding. An Indian, for example, finds European orchestral music intolerably noisy, complicated, over-intellectual, inhuman. It seems incredible to him that anyone should be able to perceive beauty and meaning, to recognize an expression of the deepest and subtlest emotions, in this elaborate cacophony. And yet, if he has patience and listens to enough of it, he will come at last to realize, not only theoretically, but also by direct, immediate intuition, that this music possesses all the qualities which Europeans claim for it. Of the significant and pleasurable experiences of life only the simplest are open indiscriminately to all. The rest cannot be had except by those who have undergone a suitable training. One must be trained even to enjoy the pleasures of alcohol and tobacco; first whiskies seem revolting, first pipes turn even the strongest of boyish stomachs. Similarly, first Shakespeare sonnets seem meaningless; first Bach fugues, a bore; first differential equations, sheer torture. But training changes the nature of our spiritual experiences. In due course, contact with an obscurely beautiful poem, an elaborate piece of counterpoint or of mathematical reasoning, causes us to feel direct intuitions of beauty and significance.
