Capacity is not the same thing as genius. Capacity may be described to relate to the quantity of knowledge, however acquired; genius to its quality and the mode of acquiring it. Capacity is a power over given ideas or combinations of ideas; genius is the power over those which are not given, and for which no obvious or precise rule can be laid down. Or capacity is power of any sort: genius is power of a different sort from what has yet been shown. A retentive memory, a clear understanding is capacity, but it is not genius. The admirable Crichton was a person of prodigious capacity; but there is no proof (that I know) that he had an atom of genius. His verses that remain are dull and sterile. He could learn all that was known of any subject: he could do any thing if others could show him the way to do it. This was very wonderful: but that is all you can say of it. It requires a good capacity to play well at chess: but, after all, it is a game of skill, and not of genius. Know what you will of it, the understanding still moves in certain tracks in which others have trod before it, quicker or slower, with more or less comprehension and presence of mind. The greatest skill strikes out nothing for itself, from its own peculiar resources; the nature of the game is a thing determinate and fixed: there is no royal or poetical road to check-mate your adversary. There is no place for genius but in the indefinite and unknown. The discovery of the binomial theorem was an effort of genius; but there was none shown in Jedediah Buxton’s being able to multiply 9 figures by 9 in his head. If he could have multiplied 90 figures by 90 instead of 9, it would have been equally useless toil and trouble.[19] He is a man of capacity who possesses considerable intellectual riches: he is a man of genius who finds out a vein of new ore. Originality is the seeing nature differently from others, and yet as it is in itself. It is not singularity or affectation, but the discovery of new and valuable truth. All the world do not see the whole meaning of any object they have been looking at. Habit blinds them to some things: short-sightedness to others. Every mind is not a gauge and measure of truth. Nature has her surface and her dark recesses. She is deep, obscure, and infinite. It is only minds on whom she makes her fullest impressions that can penetrate her shrine or unveil her _Holy of Holies_. It is only those whom she has filled with her spirit that have the boldness or the power to reveal her mysteries to others. But nature has a thousand aspects, and one man can only draw out one of them. Whoever does this, is a man of genius. One displays her force, another her refinement, one her power of harmony, another her suddenness of contrast, one her beauty of form, another her splendour of colour. Each does that for which he is best fitted by his particular genius, that is to say, by some quality of mind in which the quality of the object sinks
