Every human action gains in honor, in grace, in all true magnificence, by its regard to things that are to come. It is the far sight, the quiet and confident patience, that, above all other attributes, separate man from man, and near him to his Maker; and there is no action nor art, whose majesty we may not measure by this test. Therefore, when we build, let us think that we build for ever. Let it not be for present delight, nor for present use alone; let it be such work as our descendants will thank us for, and let us think, as we lay stone on stone, that a time is to come when those stones will be held sacred because our hands have touched them, and that men will say as they look upon the labor and wrought substance of them, ‘See! this our fathers did for us.’
The Seven Lamps of Architecture, by John Ruskin.. I am deep into Ruskin at the moment, so fair warning: there could be a good many quotations from him in the coming days.
