The real effects of fitness.

When I excluded proportion and fitness from any share in beauty, I did not by any means intend to say that they were of no value, or that they ought to be disregarded in works of art. Works of art are the proper sphere of their power; and here it is that they have their full effect. Whenever the wisdom of our Creator intended that we should be affected with anything, he did not confide the execution of his design to the languid and precarious operation of our reason; but he endued it with powers and properties that prevent the understanding, and even the will; which, seizing upon the senses and imagination, captivate the soul, before the understanding is ready either to join with them, or to oppose them. It is by a long deduction, and much study, that we discover the adorable wisdom of God in his works: when we discover it the effect is very different, not only in the manner of acquiring it, but in its own nature, from that which strikes us without any preparation from the sublime or the beautiful. How different is the satisfaction of an anatomist, who discovers the use of the muscles and of the skin, the excellent contrivance of the one for the various movements of the body, and the wonderful texture of the other, at once a general covering, and at once a general outlet as well as inlet; how different is this from the affection which possesses an ordinary man at the sight of a delicate, smooth skin, and all the other parts of beauty, which require no investigation to be perceived! In the former case, whilst we look up to the Maker with admiration and praise, the object which causes it may be odious and distasteful; the latter very often so touches us by its power on the imagination, that we examine but little into the artifice of its contrivance; and we have need of a strong effort of our reason to disentangle our minds from the allurements of the object, to a consideration of that wisdom which invented so powerful a machine. The effect of proportion and fitness, at least so far as they proceed from a mere consideration of the work itself, produce approbation, the acquiescence of the understanding, but not love, nor any passion of that species.
