Again, the term “imagination” is sometimes confined to intellectual processes in the fine arts: dramas, novels, etc., are works of imagination. Now dramas and novels all proceed upon one method, namely: they begin by stating or insinuating an hypothesis concerning certain persons in a given situation, and then deducing (that is reasoning out) the consequences, occasionally helping the plot by further assumptions: at least that is how it appears, though probably the main incident of the plot is thought of first, and then an hypothesis is framed that conveniently leads up to it. And if the reasoning is feeble, and if the subsidiary assumptions are too numerous or too facile, we say the work is flimsy or improbable—allowing for the genre; for a romance is not expected to be as probable as a modern novel. Gulliver’s Travels afford the most perfect example of this method; for each voyage begins with a frank absurdity—men six inches or sixty feet high, a flying island, rational horses; but this being granted, the sequel makes tolerable logic. Well, many scientific investigations seem to follow exactly the same method—begin with an hypothesis, deduce the consequences, and occasionally help out the argument with further hypotheses (though that is not all): and here again the conclusion is usually thought of first, and the hypothesis invented to explain it. If it be said that the scientist believes his hypothesis to be true, whilst the romancer does not, it may be replied that the scientist sometimes expressly warns us that his assumption is only a “working hypothesis,” which may not be true (though he thinks it may be), whereas early epic poets and minstrels often regarded their work as by no means without a foundation in fact.
Imagination and reasoning, then, are closely allied or interwoven, and the contrasting of them depends entirely upon this, that there is a sense in which imagination is not a presentation of truth or matter-of-fact, whether it is believed to be or not; and a sense in which reasoning is devoted solely to the discovery of truth concerning facts, and to that end is protected by a methodology, carefully comparing its premises, carefully verifying its conclusions; whereas the imagination that is contrasted with reasoning knows nothing of a methodology nor of verification. Even the modern novelist, a great part of whose hypothesis is usually true—the present state of society, facts of history or geography, etc.—does not pretend to present a truth of fact. It belongs to his art to play at reasoning; he has learnt to play the game very well; but it remains play: he aims at and attains not truth but verisimilitude. And when we look back on the history of fiction we see (on the whole) the verisimilitude growing, age by age, slighter and fainter; till in early romance and poetry it is disturbed and broken and destroyed by stories about monsters, impossible heroes, magicians and gods, believed at one time to be true, and just the same as stories still believed by barbarians and savages, but which we believe no longer.
It is such stories as these last, including all superstitions, that I especially call “imagination-beliefs.” The term includes all false beliefs, but with the rest I am not directly concerned. How are imagination-beliefs possible?
