And when I say _learn_, I mean learn in the least official and the most efficacious way. I do not mean merely that, looking at a statue like the Hermes, a certain fact is borne in upon our intelligence, the fact of all vitality being dependent on harmony. I mean that perhaps, nay probably, without any such formula, our whole nature becomes accustomed to a certain repeated experience, our whole nature becomes adapted thereunto, and acts and reacts in consequence, by what we call intuition, instinct. It is not with our intellect alone that we possess such a fact, as we might intellectually possess that twice two is four, or that Elizabeth was the daughter of Henry VIII., knowing casually what we may casually also forget; we possess, in such a way that forgetting becomes impossible, with our whole soul and our whole being, re-living that fact with every breath that we draw, with every movement we make, the first great lesson of art, that vitality means harmony. Let us look at this fact, and at its practical applications, apart from all aesthetic experience. All life is harmony; and all improvement in ourselves is therefore, however unconsciously, the perceiving, the realising, or the establishing of harmonies, more minute or more universal. Yes, curious and unpractical as it may seem, harmonies, or, under their humbler separate names--arrangements, schemes, classifications, are the chief means for getting the most out of all things, and particularly the most out of ourselves. For they mean, first of all, unity of means for the attaining of unity of effect, that is to say, incalculable economy of material, of time, and of effort; and secondly, unity of effect produced, that is to say, economy even greater in our power of perceiving and feeling: nothing to eliminate, nothing against whose interruptions we waste our energy, our power of becoming more fit in the course of striving.
