It is not enough, therefore, that a people should be numerous and wealthy; it must, with all its wealth and its power, contain a large proportion of poor and even oppressed and enslaved subjects. If it has not got these, it must master and make use of other foreign cultures as a substitute. That is what Rome did; it is what America is doing. It is terrible, but comprehensible. For up to this point the unconscious processes of Nature, the law of mutual strife, has prevailed. So far, collective organizations have been beasts of prey; only now are they about to cross the boundaries of the human order. Comprehensible and explicable. For all creations of culture hold together; one cannot pursue the cheaper varieties while renouncing the more costly. There is no cheap culture. In their totality they demand outlay, the most tremendous outlay known to history, the only outlay by which human toil is recompensed, over and above the supply of absolute necessaries. The creations of civilisation, like all things living and dead, follow on each other--plants, men, beasts and utensils have their sequence generation after generation. Men must paint and look at pictures for ten thousand years before a new picture comes into existence. Our poetry and our research are the fruit of thousands of years. This is no disparagement to genius in work and thought, genius is at once new, ancient and eternal, even as the blossom is a new thing on the old stem, and belongs to an eternal type. When we hear that a native in Central Africa or New Zealand has produced an oil-painting we know that somehow or other he must have got to Paris. When a European artist writes or paints in Tahiti, what he produces is not a work of Tahitian culture. When civilisation has withered away on some sterilized soil, it can only be revived by new soil and foreign seed.
