Seeing consists of the grasping of structural features rather than the indiscriminate recording of detail.

Rudolf ArnheimFrom building a fire one can learn something about artistic composition. If you use only small kindling and large logs, the fire will quickly eat up the small pieces but will not become strong enough to attack the large ones. You must supply a scale of sizes from the smallest to the largest. The human eye also will not make its way into a painting or building unless a continuum of shapes leads from the small to the large, from the large to the small.
Rudolf ArnheimBoth art and science are bent on the understanding of the forces that shape existence, and both call for a dedication to what is. Neither of them can tolerate capricious subjectivity because both are subject to their criteria of truth. Both require precision, order, and discipline because no comprehensible statement can be made without these. Both accept the sensory world as what the Middle Ages called signatura regrum, the signature of things, but in quite different ways.
