It now remains to discover, so to speak, its location. In what part, then, of man may this self-evidenced, yet elusive, Truth or power be said to reside? It cannot be in the senses; for the senses can impart no more than they receive. Is it, then, in the mind? Here we are compelled to ask, What is understood by the mind? Do we mean the understanding? We can trace no relation between the Truth we would class and the reflective faculties. Or in the moral principle? Surely not; for we can predicate neither good nor evil by the Truth in question. Finally, do we find it identified with the truth of the Spirit? But what is the truth of the Spirit but the Spirit itself,--the conscious _I_? which is never even thought of in connection with it. In what form, then, shall we recognize it? In its own,--the form of Life,--the life of the Human Being; that self-projecting, realizing power, which is ever present, ever acting and giving judgment on the instant on all things corresponding with its inscrutable self. We now assign it a distinctive epithet, and call it Human. It is a common saying, that there is more in a name than we are apt to imagine. And the saying is not without reason; for when the name happens to be the true one, being proved in its application, it becomes no unimportant indicator as to the particular offices for which the thing named was designed. So we find it with respect to the Truth of which we speak; its distinctive epithet marking out to us, as its sphere of action, the mysterious intercourse between man and man; whether the medium consist in words or colors, in thought or form, or in any thing else on which the human agent may impress, be it in a sign only, his own marvellous life. As to the process or _modus operandi_, it were a vain endeavour to seek it out: that divine secret must ever to man be an humbling darkness. It is enough for him to know that there is that within him which is ever answering to that without, as life to life,--which must be life, and which must be true. We proceed now to the third characteristic. It has already been stated, in the general definition, what we would be understood to mean by the term Invention, in its particular relation to Art; namely, any unpractised mode of presenting a subject, whether by the combination of forms already known, or by the union and modification of known but fragmentary parts into a new and consistent whole: in both cases tested by the two preceding characteristics.
