Perfect form consists in the "ability to convey thought and emotion with perfect fidelity." The general qualities characteristic of perfect form, which have been outlined by Professor Winchester, in his _Principles of Literary Criticism_, are: (1) precision or clearness; (2) energy or force; (3) delicacy or emotional harmony; and (4) personality. Precision or clearness demands the precise value and meaning of words. It requires that words have the power of denotation. It appeals to the intellect of the reader or listener and demands that language be neither vague nor ambiguous nor obscure. Energy or force demands that perfect form have the quality of emotion. It requires that words have especially the power of connotation. It appeals to the emotions of the reader or listener and has the power to hold the attention. It demands of language that sympathy which will imply what it would suggest. Delicacy or emotional harmony demands that perfect form please the taste. It requires that an emotional harmony be secured by a selection and arrangement of the melody of words and of the emotional associations which, together with the meanings, are tied up in words. It demands that words have the power of perfect adaptation to the thought and feeling they express, that words have both the power of denotation and of connotation. It appeals to the æsthetic sense of the reader or listener, it gives to form beauty and charm. Personality is the influence of the author, the charm of individuality, and suggests the character of the writer.
