The perceptive critical taste is, so to speak, the female analogue to the male quality of productive talent or genius. Not capable of _begetting_ great work itself, it consists in a capacity of _reception_, that is to say, of recognizing as such what is right, fit, beautiful, or the reverse; in other words, of discriminating the good from the bad, of discovering and appreciating the one and condemning the other. In appreciating a genius, criticism should not deal with the errors in his productions or with the poorer of his works, and then proceed to rate him low; it should attend only to the qualities in which he most excels. For in the sphere of intellect, as in other spheres, weakness and perversity cleave so firmly to human nature that even the most brilliant mind is not wholly and at all times free from them. Hence the great errors to be found even in the works of the greatest men; or as Horace puts it, _quandoque bonus dormitat Homerus_. That which distinguishes genius, and should be the standard for judging it, is the height to which it is able to soar when it is in the proper mood and finds a fitting occasion--a height always out of the reach of ordinary talent. And, in like manner, it is a very dangerous thing to compare two great men of the same class; for instance, two great poets, or musicians, or philosophers, or artists; because injustice to the one or the other, at least for the moment, can hardly be avoided. For in making a comparison of the kind the critic looks to some particular merit of the one and at once discovers that it is absent in the other, who is thereby disparaged. And then if the process is reversed, and the critic begins with the latter and discovers his peculiar merit, which is quite of a different order from that presented by the former, with whom it may be looked for in vain, the result is that both of them suffer undue depreciation. There are critics who severally think that it rests with each one of them what shall be accounted good, and what bad. They all mistake their own toy-trumpets for the trombones of fame. A drug does not effect its purpose if the dose is too large; and it is the same with censure and adverse criticism when it exceeds the measure of justice.
