intuitive faculty with which he skimmed the surfaces of things, and unconsciously formed his opinions. Common sense is the just result of the sum-total of such unconscious impressions in the ordinary occurrences of life, as they are treasured up in the memory, and called out by the occasion. Genius and taste depend much upon the same principle exercised on loftier ground and in more unusual combinations. I am glad to shelter myself from the charge of affectation or singularity in this view of an often debated but ill-understood point, by quoting a passage from Sir Joshua Reynolds’s Discourses, which is full, and, I think, conclusive to the purpose. He says, ‘I observe, as a fundamental ground common to all the Arts with which we have any concern in this Discourse, that they address themselves only to two faculties of the mind, its imagination and its sensibility. ‘All theories which attempt to direct or to control the Art, upon any principles falsely called rational, which we form to ourselves upon a supposition of what ought in reason to be the end or means of Art, independent of the known first effect produced by objects on the imagination, must be false and delusive. For though it may appear bold to say it, the imagination is here the residence of truth. If the imagination be affected, the conclusion is fairly drawn; if it be not affected, the reasoning is erroneous, because the end is not obtained; the effect itself being the test, and the only test, of the truth and efficacy of the means. ‘There is in the commerce of life, as in Art, a sagacity which is far from being contradictory to right reason, and is superior to any occasional exercise of that faculty; which supersedes it; and does not wait for the slow progress of deduction, but goes at once, by what appears a kind of intuition, to the conclusion. A man endowed with this faculty feels and acknowledges the truth, though it is not always in his power, perhaps, to give a reason for it; because he cannot recollect and bring before him all the materials that gave birth to his opinion; for very many and very intricate considerations may unite to form the principle, even of small and minute parts, involved in, or dependent on, a great system of things:—though these in process of time are forgotten, the right impression still remains fixed in his mind.
