The real answer is here again a new version of the old Puritan answer. The Puritan fell back upon the will of God revealed through the Bible, whose authority was manifest by the inner light. If the wicked were allowed to triumph for a time, there was no danger of being misled by their success, for they were condemned in advance by the plain fact of their renunciation of the inspired guide. For Carlyle, the 'hero' takes the place of, or rather is put side by side with, the older organs of inspiration. Every hero conveys in fact a new revelation to mankind; he conveys a divine message, not, it is true, with infallible precision, or without an admixture of human error, but still the very kernel and essence of his teaching. He may come as prophet, king, poet, or philosopher, and you may reject or accept his message at your peril. You may recognise it, as the Puritan recognised the authority of his Bible, by the spontaneous witness of your higher nature, and you will recognise it so long as you have not given yourself up to believe a lie. And if you demand some external proofs you must be referred, not to some particular signs and wonders, but to what you may, if you please, call the 'success' of the message; the fact, that is, that the hero has contributed some permanent element to the thoughts and lives of mankind, that he has revealed some enduring truth, created some permanent symbol of our highest feelings, or wrought some organic change in the very structure of society. There is a danger undoubtedly of confounding some temporary crystal palace or dazzling edifice of mere glass with an edifice founded on the rock and solid as the pyramids. The hero may be confounded with the sham, as unfortunately shams and realities are most frequently confounded in this world. But they differ for all that, and the true man recognises the difference, as the religious man knows the hypocrite from the saint. The test is indifferently the truth or the soundness of the work; they must coincide; but the test can only be applied by one who really loves the truth.
It is easy to point out the dangers of this position. It rests, after all, you may say upon the individual conviction, and lends itself too easily to that kind of dogmatism in which Carlyle indulged so freely, and which consists in asserting that any doctrine or system which he dislikes is an incarnate lie, and pronouncing that it is therefore doomed to failure. And, on the other hand, it may be equally perverted in the opposite direction by claiming a sacred character for every 'lie' not yet exploded. Carlyle, beyond all question, was a man of intense prejudices, and the claim to inspiration, even to the inspiration of our teachers, very easily passes into a deification of our own prejudices. No one was more liable to that error; but it is better worth our while to look at some other aspect of his teaching.
