FAITH may be defined as fidelity to our own being, so far as such being is not and cannot become an object of the senses; and hence, by clear inference or implication to being generally, as far as the same is not the object of the senses; and again to whatever is affirmed or understood as the condition, or concomitant, or consequence of the same. This will be best explained by an instance or example. That I am conscious of something within me peremptorily commanding me to do unto others as I would they should do unto me; in other words a categorical (that is, primary and unconditional) imperative; that the maxim (_regula maxima_, or supreme rule) of my actions, both inward and outward, should be such as I could, without any contradiction arising therefrom, will to be the law of all moral and rational beings. This, I say, is a fact of which I am no less conscious (though in a different way), nor less assured, than I am of any appearance presented by my outward senses. Nor is this all; but in the very act of being conscious of this in my own nature, I know that it is a fact of which all men either are or ought to be conscious; a fact, the ignorance of which constitutes either the non-personality of the ignorant, or the guilt; in which latter case the ignorance is equivalent to knowledge wilfully darkened. I know that I possess this knowledge as a man, and not as Samuel Taylor Coleridge; hence, knowing that consciousness of this fact is the root of all other consciousness, and the only practical contradistinction of man from the brutes, we name it the conscience, by the natural absence or presumed presence of which the law, both Divine and human, determines whether X Y Z be a thing or a person; the conscience being that which never to have had places the objects in the same order of things as the brutes, for example, idiots, and to have lost which implies either insanity or apostasy. Well, this we have affirmed is a fact of which every honest man is as fully assured as of his seeing, hearing, or smelling. But though the former assurance does not differ from the latter in the degree, it is altogether diverse in the kind; the senses being morally passive, while the conscience is essentially connected with the will, though not always, nor indeed in any case, except after frequent attempts and aversions of will dependent on the choice. Thence we call the presentations of the senses impressions, those of the conscience commands or dictates. In the senses we find our receptivity, and as far as our personal being is concerned, we are passive, but in the fact of the conscience we are not only agents, but it is by this alone that we know ourselves to be such—nay, that our very passiveness in this latter is an act of passiveness, and that we are patient (_patientes_), not, as in the other case, _simply_ passive.
