Dialecʹtics
.Metaphysics; the art of disputation; that strictly logical discussion which leads to reliable results. The product or result is ideas, which, being classified, produce knowledge; but all knowledge being of the divine types, must conduce more or less to practical results and good morals. (Greek, dialego, to speak thoroughly.)
⁂ Kant used the word to signify the theory of fallacies, and Hegel for that concept which of necessity develops its opposite.
