"It is well known, that, in all questions submitted to the understanding, prejudice is destructive of sound judgment, and perverts all operations of the intellectual faculties: it is no less contrary to good taste; nor has it less influence to corrupt our sentiments of beauty. It belongs to _good sense_ to check its influence in both cases; and in this respect, as well as in many others, reason, if not an essential part of taste, is at least requisite to the operations of this latter faculty. In all the nobler productions of genius, there is a mutual relation and correspondence of parts; nor can either the beauties or blemishes be perceived by him whose thought is not capacious enough to comprehend all those parts, and compare them with each other, in order to perceive the consistence and uniformity of the whole. Every work of art has also a certain end or purpose for which it is calculated; and is to be deemed more or less perfect, as it is more or less fitted to attain this end." To a repetition of this, Burke adds some useful remarks:-- "As many of the works of imagination are not confined to representation of sensible objects, nor to efforts upon the passions, but extend themselves to the manners, the characters, the actions, and designs of men, their relations, their virtues and vices, they come within the province of the judgment, which is improved by attention and by the habit of reasoning. "The cause of a wrong taste is a defect of judgment. And this may arise from a natural weakness of understanding (in whatever the strength of that faculty may consist), or which is much more commonly the case, it may arise from a want of proper and well-directed exercise, which alone can make it strong and ready. Beside that ignorance, inattention, prejudice, rashness, levity, obstinacy, in short, all those passions, and all those vices which pervert the judgment in other matters, prejudice it no less in this its more refined and elegant province. These causes produce different opinions upon everything which is an object of the understanding, without inducing us to suppose, that there are no settled principles of reason. "A rectitude of judgment in the arts, which may be called a good taste, does in a great measure depend upon sensibility; because, if the mind has no bent to the pleasures of the imagination, it will never apply itself sufficiently to works of that species to acquire a competent knowledge in them. But though a degree of sensibility is requisite to form a good judgment, yet a good judgment does not necessarily arise from a quick sensibility of pleasure; it frequently happens that a very poor judge, merely by force of a greater complexional sensibility, is more affected by a poor piece, than the best judge by the most perfect; for as everything new, extraordinary, grand, or passionate, is well calculated to affect such a person, and that the faults do not affect him, his pleasure is more pure and unmixed.
