The rational conscience of average humanity is a thing of such dense and rigid and unimaginative vision that it is inevitable that its "truth" should clash with the secrets revealed by the aesthetic sense. The cause, why the aesthetic sense seems to come on the scene with an apparatus of valuation so much more advanced and refined than that possessed by the conscience or by the reason, is that both conscience and reason are continually being applied to action, to conduct, to the manipulation of practical affairs, and are bound in this commerce with superficial circumstance to grow a little blunt and gross and to lose something of their fine edge. Conscience and reason, in the hurly-burly and pell-mell of life, are driven to compromise, to half-measures, to the second-best. Conscience is compelled to be satisfied with something less than its own rigid demands. Reason is compelled to accept something less than its own rigid demands. Both of these things tend to become, under the pressure of the play of circumstance, pragmatical, time-serving, and opportunist. But the aesthetic sense, although in itself it has always room for infinite growth, is in its inherent nature unable to compromise; unable to bend this way and that; unable to dally with half-measures. Any action, in a world of this kind, necessarily implies compromise; and since goodness is so largely a matter of action, goodness is necessarily penetrated by a spirit of compromise. Indeed it may be said that a certain measure of common-sense is of the very essence of goodness. But what has common-sense to do with art? Common-sense has never been able, and never will be able, to understand even the rudiments of art. For art is the half-discovery of something that must always seem an impossibility to common-sense; and it is the half-creation of something that must always render common-sense irrelevant and unimportant. Truth, again, in a world of so infinite a complication, must frequently have to remain an open question, a suspended judgment, an antinomy of opposites. The agnostic attitude--as, for instance, in the matter of the immortality of the soul--may in certain cases come to be the ultimate gesture of what we call the truth.
