So Theseus, of the play of the rude artisans of Athens, excusing all art: "The best in this kind are but shadows." So Hamlet; so Prospero.

Action is vital in us, and has a double order of phenomena; so far as these are physical, their law is one of the physical world, and interests us no more than other physical laws; so far as they belong in the inward world of self-consciousness, their law is spiritual, and has human interest as being operant in a soul like our own. The external fact is seized by the eye as a part of nature; the internal fact is of the unseen world, and is beheld only in the light which is within our own bosoms—it is spiritually discerned. On the stage plainly this is the case. So far as the actions are for the eye of sense alone they are merely spectacular; so far as they express desires and energies, they are dramatic, and these we do not see but feel according as our experience permits us so to comprehend them. We contemplate a world of emotion there in connection with the active energy of the will, a world of character in operation in man; we feed it from our life, interpret it therefrom, build it up in ourselves, suffering the illusion till absorbed in what is arising in our consciousness under the actor's genius we become ourselves the character. The greatest actor is he who makes the spectator play the part. So far is the drama from the scene that it goes on in our own bosoms; there is the stage without any illusion whatsoever; the play in vital for the moment in ourselves.

And what is true of the stage is true of life. It is only through our own hearts that we look into the hearts of others. We interpret the external signs of sense in terms of personality and experience known only within us; the life of will, head, and heart that we ascribe to our nearest and dearest friends is something imagined, something never seen any more than our own personality. Thus our knowledge of them is not only fragmentary, as has been said; it is imaginative even within its limits. It is, in reality as well as in art, a shadow-world we live in, believing that within its sensuous films a spirit like unto ourselves abides,—the human soul, though never seen face to face. To enter this substantial world behind the phenomena of human life as sensibly shown in imagination, to know the invisible things of personality and experience, and to set them forth as a spiritual order, is the main end of ideal art. Though in plot the outward order is brought into the fullest prominence, and may seem to occupy the field, yet it is significantly only the shadow of that order within.

In thus presenting plot as the means by which the history of a single soul is externalized, one important element has been excluded from consideration. The causal chain of events, which constitutes plot, has a double unity, answering to the double order of phenomena in action as a state of mind and a state of external fact. Under one aspect, so much of the action as is included in any single life and is there a linked sequence of mental states, has its unity in the personality of that individual. Under the other aspect, the entire action which sets forth the relations of all the characters involved, of their several courses of experience as elements in the working out of the joint result, has its unity in the constitution of the universe,—the impersonal order, that structure of being itself, which is independent of man's will, which is imposed upon him as a condition of existence, and which he must accept without appeal. This necessity, to give it the best name, to which man is exposed without and subjected within, is in its broadest conception the power that increases life, and all things are under its sway. Its sphere is above man's will; he knows it as immutable law in himself as it is in nature; it is the highest object of his thoughts. Its workings are submitted to his observation and experiment as a part of the world of knowledge; he sees its operation in individuals, social groups, and nations, and sets it forth in the action of the lyric, the drama, and the epic as the law of life. In its sphere is the higher unity of plot by virtue of which it integrates many lives in one main action. Such, then, is the nature of plot as intermediary between man and his environment, but deeply engaged in the latter, and not to be freed from it even by a purely spiritualistic philosophy; for though we say that, as under one aspect plot shadows forth the unseen world of the soul's life, so under the other it shadows forth the invisible will of God, we do not escape from the outward world. Sense is still the medium by which only man knows his brother man and God also as through a glass darkly,—

"The painted veil which those who live call life."

It separates all spirits, the beautiful but dense element in which the pure soul is submerged.

It is necessary only to summarize the characteristics of plot which are merely parallel to those of type already illustrated. Plot may be simple or complex; it may be more or less involved in physical conditions in proportion as it lays stress on its machinery or its psychology; it must be important, as the type must be high, but important by virtue of its essential human meaning and not of its accidents; it is a fragment of destiny only, but in this falls in with the way life in others is known to us; if it passes into the superhuman world, it must retain human significance and be brought back to man's life by devices similar to those used in the type for the same purpose; it rises in value in proportion to the universality it contains, and gains depth and permanence as it is interpretative of common human fate at all times and among all men; it may be purely imaginary or founded on actual incidents; and its exemplary interpretation of man's life is its substance, and constitutes its ideality.

In the discussion of type and plot, the concrete nature of the world of art, which was originally stated to be the characteristic work of the creative reason, or imagination acting in conformity with truth, has been assumed; but no reason has been given for it, because it seemed best to develop first with some fulness the nature of that inward order which is thus projected in the forms of art. It belongs to the frailty of man that he seizes with difficulty and holds with feebleness the pure ideas of the intellect, the more in proportion as they are removed from sense; and he seeks to support himself against this weakness by framing sensible representations of the abstract in which the mind can rest. Thus in all lands and among savage tribes, as well as in the most civilized nations, symbols have been used immemorially. The flag of a nation has all its meaning because it is taken as a physical token of national honour, almost of national life itself. The Moslem crescent, the Christian cross, have only a similar significance, a bringing near to the eye of what exists in reality only for the mind and heart. A symbol, however, is an arbitrary fiction, and stands to the idea as a metaphor does to the thing itself. In literature the parable of the mustard seed to which the kingdom of heaven was likened, exemplifies symbolical or metaphorical method; but the tale of the court of Arthur's knights, ideal method; between them, and sharing something of both, lies allegorical method. Idolatry is the religion of symbolism, for the image is not the god; Christianity is the religion of idealism, for Christ is God incarnate. Idealism presents the reality itself, the universal truth made manifest in the concrete type, and there present and embodied in its characteristics as they are, not merely arbitrarily by a fiction of thought, symbolically or allegorically.

The way in which type concretes truth is sufficiently plain; but it may be useful, with respect to plot, to draw out more in detail the analogy which has been said to exist between it and an illustrative scientific experiment. If scientific law is declared experimentally, the course of nature is modified by intent; certain conditions are secured, certain others eliminated; a selected train of phenomena is then set in motion to the end that the law may be illustrated, and nothing else. In a perfect experiment the law is in full operation. In plot there is a like selection of persons, situations, and incidents so arranged as to disclose the working of that order which obtains in man's life. The law may be simple and shown by means of few persons and incidents in a brief way, as in ancient drama, or complex and exhibited with many characters in an abundance of action over a wide scene as in Shakspere; in either case equally there is a selection from the whole mass of man's life of what shall illustrate the causal union in its order and show it in action. The process in the epic or prose narrative is the same. The common method of all is to present the universal law in a particular instance made for the purpose.

In thus clothing itself in concrete form, truth suffers no transformation; it remains what it was, general truth, the very essence of type and plot being, as has been said, to preserve this universality in the particular instance. There is a sense in which this general truth is more real, as Plato thought, than particulars; a sense in which the phenomenal world is less real than the system of nature, for phenomena come and go, but the law remains; a sense in which the order in man's breast is more real than he is, in whom it is manifest, for the form of ideas, the mould of law, are permanent, but their expression in us transitory. It is this higher realism, as it was anciently called, that the mind strives for in idealism,—this organic form of life, the object of all rational knowledge. Types, under their concrete disguise, are thus only a part of the general notions of the mind found in every branch of knowledge and necessary to thought; plots, similarly, are only a part of the general laws of the ordered world; literature in using them, and specializing them in concrete form by which alone they differ in appearance from like notions and laws elsewhere, merely avails itself of that condensing faculty of the mind which most economizes mental effort and loads conceptions with knowledge. In the type it is not personal, but human character that interests the mind; in plot, it is not personal, but human fate.
