"The best thing you can do for your fellow, next to rousing his conscience, is--not to give him things to think about, but to wake things up that are in him; or say, to make him think things for himself. The best Nature does for us is to work in us such moods in which thoughts of high import arise. Does any aspect of Nature wake but one thought? Does she ever suggest only one definite thing? Does she make any two men in the same place at the same moment think the same thing? Is she therefore a failure, because she is not definite? Is it nothing that she rouses the something deeper than the understanding- -the power that underlies thoughts? Does she not set feeling, and so thinking at work? Would it be better that she did this after one fashion and not after many fashions? Nature is mood-engendering, thought-provoking: such ought the sonata, such ought the fairytale to be."
