But this is to ignore the basal fact, which is that plant life in any form is a defiance of current conditions. Art has already begun when natural processes assume a form that feeds itself, reproduces itself, and grows. The first organisms have only a local footing; they are rooted in the soil, and can turn to their advantage only the conditions characteristic of a time and place. Eventually there evolves a more resourceful unit of life, like the gardener with his cultivated plants, who is capable of inhabiting nature at large. But the method is still the same, that of playing off nature against nature; only it is now done on a larger scale, and in a more aggressive and confident spirit. The need of concession to the demands of locality is reduced, through a concession once and for all to the wider processes of nature. But in relation to its environment, life is never wholly constructive, as it is never wholly passive. Whether it appears in the form of vegetation or civilization, {24} it always involves both an adaptation of nature to itself and of itself to nature. Morality, then, is natural if life is natural; for it is defined by the same essential principles. It is related to life as a later to an earlier phase of one development. The organization of life answers the self-preservative impulse with which life begins; the deliberate fulfilment of a human purpose is only life grown strong enough through organization to conduct a larger and more adventurous enterprise.
