"If until now (i.e. 1910-12) colour and form were used as inner agents, it was mainly done subconsciously. The subordination of composition to geometrical form is no new idea (cf. the art of the Persians). Construction on a purely spiritual basis is a slow business, and at first seemingly blind and unmethodical. The artist must train not only his eye but also his soul, so that it can weigh colours in its own scale and thus become a determinant in artistic creation. If we begin at once to break the bonds that bind us to nature and to devote ourselves purely to combination of pure colour and independent form, we shall produce works that are mere geometric decoration, resembling something like a necktie or a carpet. Beauty of form and colour is no sufficient aim by itself, despite the assertions of pure aesthetes or even of naturalists obsessed with the idea of "beauty". It is because our painting is still at an elementary stage that we are so little able to be moved by wholly autonomous colour and form composition. The nerve vibrations are there (as we feel when confronted by applied art), but they get no farther than the nerves because the corresponding vibrations of the spirit which they call forth are weak."
