For my own part, being of a superstitious nature, given readily to imagine alarming causes, I immediately, on first getting these mystic hints from Lentulus, concluded that he held a number of entirely original poems, or at the very least a revolutionary treatise on poetics, in that melancholy manuscript state to which works excelling all that is ever printed are necessarily condemned; and I was long timid in speaking of the poets when he was present. For what might not Lentulus have done, or be profoundly aware of, that would make my ignorant impressions ridiculous? One cannot well be sure of the negative in such a case, except through certain positives that bear witness to it; and those witnesses are not always to be got hold of. But time wearing on, I perceived that the attitude of Lentulus towards the philosophers was essentially the same as his attitude towards the poets; nay, there was something so much more decided in his mode of closing his mouth after brief speech on the former, there was such an air of rapt consciousness in his private hints as to his conviction that all thinking hitherto had been an elaborate mistake, and as to his own power of conceiving a sound basis for a lasting superstructure, that I began to believe less in the poetical stores, and to infer that the line of Lentulus lay rather in the rational criticism of our beliefs and in systematic construction. In this case I did not figure to myself the existence of formidable manuscripts ready for the press; for great thinkers are known to carry their theories growing within their minds long before committing them to paper, and the ideas which made a new passion for them when their locks were jet or auburn, remain perilously unwritten, an inwardly developing condition of their successive selves, until the locks are grey or scanty. I only meditated improvingly on the way in which a man of exceptional faculties, and even carrying within him some of that fierce refiner's fire which is to purge away the dross of human error, may move about in society totally unrecognised, regarded as a person whose opinion is superfluous, and only rising into a power in emergencies of threatened black-balling. Imagine a Descartes or a Locke being recognised for nothing more than a good fellow and a perfect gentleman--what a painful view does such a picture suggest of impenetrable dulness in the society around them!
