This has happened to some extent in the whole world, on account of natural conditions which limit the forms of life possible in one region; for nature is intolerant in her laxity and punishes too great originality and heresy with death. Such moral integration has occurred very markedly in every good race and society whose members, by adapting themselves to the same external forces, have created and discovered their common soul. Spiritual unity is a natural product. There are those who see a great mystery in the presence of eternal values and impersonal ideals in a moving and animal world, and think to solve that dualism, as they call it, by denying that nature can have spiritual functions or spirit a natural cause; but nothing can be simpler if we make, as we should, existence the test of possibility. _Ab esse ad posse valet illatio_. Nature is a perfect garden of ideals, and passion is the perpetual and fertile soil for poetry, myth, and speculation. Nor is this origin merely imputed to ideals by a late and cynical observer: it is manifest in the ideals themselves, by their subject matter and intent. For what are ideals about, what do they idealise, except natural existence and natural passions? That would be a miserable and superfluous ideal indeed that was nobody’s ideal of nothing. The pertinence of ideals binds them to nature, and it is only the worst and flimsiest ideals, the ideals of a sick soul, that elude nature’s limits and belie her potentialities. Ideals are forerunners or heralds of nature’s successes, not always followed, indeed, by their fulfilment, for nature is but nature and has to feel her way; but they are an earnest, at least, of an achieved organisation, an incipient accomplishment, that tends to maintain and root itself in the world. To speak of nature’s successes is, of course, to impute success retroactively; but the expression may be allowed when we consider that the same functional equilibrium which is looked back upon as a good by the soul it serves, first creates individual being and with it creates the possibility of preference and the whole moral world; and it is more than a metaphor to call that achievement a success which has made a sense of success possible and actual. That nature cannot intend or previously esteem those formations which are the condition of value or intention existing at all, is a truth too obvious to demand repetition; but when those formations arise they determine estimation, and fix the direction of preference, so that the evolution which produced them, when looked back upon from the vantage-ground thus gained, cannot help seeming to have been directed toward the good now distinguished and partly attained. For this reason creation is regarded as a work of love, and the power that brought order out of chaos is called intelligence. [Sidenote: Living stability.]
