Now the work of art also represents a state of final equilibrium, of accomplished order and maximum relative entropy, and there are those who resent it. But art is not meant to stop the stream of life. Within a narrow span of duration and space the work of art concentrates a view of the human condition; and sometimes it marks the steps of progression, just as a man climbing the dark stairs of a medieval tower assures himself by the changing sights glimpsed through its narrow windows that he is getting somewhere after all.
Rudolf ArnheimThe line that describes the beautiful is elliptical. It has simplicity and constant change. It cannot be described by a compass, and it changes direction at every one of its points.
Rudolf ArnheimWhen the thing observed... is seen as an agglomeration of pieces, the details lose their meaning and the whole becomes unrecognizable. This is often true of snapshots in which no pattern of salient shapes organizes the mass of vague and complex nuances.
Rudolf ArnheimJust as a chemist "isolates" a substance from contaminations that distort his view of its nature and effects, so the work of art purifies significant appearance. It presents abstract themes in their generality, but not reduced to diagrams.
Rudolf ArnheimSince mechanically obtained randomness contains all kinds of possible permutations, including the most regular ones, it cannot be relied upon always to exhibit a pervasive irregularity.
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.
