Perhaps the true limit of the Science is to be discovered by the knowledge of its use. Every man is more or less a physiognomist. It is of obvious importance for us to have some knowledge of the passions and propensities of our fellow men; for these constitute the instruments of human association, and form the dangers or advantages of human intercourse. Thus, a countenance of ill temper or of habitual guile, of daring violence or of brutish profligacy, warns the spectator at once. But the knowledge of intellectual capacity is comparatively unimportant to us as either a guide or a protection, and it is therefore not given, but left to be ascertained by its practical operation. Phrenology has since taken up the challenge which Physiognomy once gave to mankind:--equally ingenious and equally fantastic, equally offering a semblance of truth, and equally incapable of leading us beyond the simple observation which strikes the eye. A well-formed head will probably contain a well-formed brain; and a well-formed brain will probably be the fittest for the operations of the intellect. But beyond this, Phrenology has not gone, and probably will never go. The attempts to define the faculties by their position in the structure of the bone or the brain, have been so perpetually contradicted by fact; its prognostics of capacity have been so perpetually defeated; and its mistakes of character have been so constantly thrown into burlesque by the precipitancy and presumption of its advocates--that common sense has abandoned it altogether; it has by common consent been abandoned to enthusiasts; and to assert its right to the name of a Science, would now hazard the title of its advocate to rationality.
