And then the degree of harmony in the different modes of expression by which a given person reveals himself is a point of profound delicacy for actor and critic. In a type of ideal perfection every signal of thought or feeling, of being or purpose, will denote precisely what it is intended to denote and nothing else, and all the simultaneous signals will agree with one another. But real characters, so far as they fall short of perfection, are inconsistent in their expressions, continually indefinite, superfluous or defective, often flatly contradictory. Multitudes of characters are so undeveloped or so ill developed that they fall into attitudes without fitness or direct significance, employ gestures vaguely or unmeaningly, and are so insincere or little in earnest that their postures, looks, motions, and voices carry opposite meanings and thus belie one another. It requires no superficial art to be able instantly to detect every incongruity of this sort, to assign it to its just cause, and to decide whether the fault arises from conscious falsity in the character or from some incompetency of the physical organism to reflect the states of its spiritual occupant. For instance, in sarcastic speech the meaning of the tone contradicts the meaning of the words. The articulation is of the head, but the tone is of the heart. So when the voice is ever so soft and wheedling, if the language of the eyes and the fingers is ferocious, he is a fool who trusts the voice. In like manner the revelations in form and attitude are deeper and more massive than those of gesture. But in order that all the expressions of the soul through the body should be marked by truth and agreement, it is necessary that the soul should be completely sincere and unembarrassed and that the body should be completely free and flexible to reflect its passing states. No character furnishes these conditions perfectly, and therefore every character will betray more or less inconsistency in its manifestations. Still, every pronounced character has a general unity of design and coloring in its type which must be kept prevailingly in view.
