The single moment of time to which art must confine itself, will lead us, I think, to such considerations. Since the artist can use but a single moment of ever-changing nature, and the painter must further confine his study of this one moment to a single point of view, while their works are made not simply to be looked at, but to be contemplated long and often, evidently the most fruitful moment and the most fruitful aspect of that moment must be chosen. Now that only is fruitful which allows free play to the imagination. The more we see the more we must be able to imagine; and the more we imagine, the more we must think we see. But no moment in the whole course of an action is so disadvantageous in this respect as that of its culmination. There is nothing beyond, and to present the uttermost to the eye is to bind the wings of Fancy, and compel her, since she cannot soar beyond the impression made on the senses, to employ herself with feebler images, shunning as her limit the visible fulness already expressed. When, for instance, Laocoon sighs, imagination can hear him cry; but if he cry, imagination can neither mount a step higher, nor fall a step lower, without seeing him in a more endurable, and therefore less interesting, condition. We hear him merely groaning, or we see him already dead. Again, since this single moment receives from art an unchanging duration, it should express nothing essentially transitory. All phenomena, whose nature it is suddenly to break out and as suddenly to disappear, which can remain as they are but for a moment; all such phenomena, whether agreeable or otherwise, acquire through the perpetuity conferred upon them by art such an unnatural appearance, that the impression they produce becomes weaker with every fresh observation, till the whole subject at last wearies or disgusts us. La Mettrie, who had himself painted and engraved as a second Democritus, laughs only the first time we look at him. Looked at again, the philosopher becomes a buffoon, and his laugh a grimace. So it is with a cry. Pain, which is so violent as to extort a scream, either soon abates or it must destroy the sufferer. Again, if a man of firmness and endurance cry, he does not do so unceasingly, and only this apparent continuity in art makes the cry degenerate into womanish weakness or childish impatience. This, at least, the sculptor of the Laocoon had to guard against, even had a cry not been an offence against beauty, and were suffering without beauty a legitimate subject of art.
