There is nothing more distinct than common sense and vulgar opinion. Common sense is only a judge of things that fall under common observation, or immediately come home to the business and bosoms of men. This is of the very essence of its principle, the basis of its pretensions. It rests upon the simple process of feeling, it anchors in experience. It is not, nor it cannot be, the test of abstract, speculative opinions. But half the opinions and prejudices of mankind, those which they hold in the most unqualified approbation and which have been instilled into them under the strongest sanctions, are of this latter kind, that is, opinions, not which they have ever thought, known, or felt one tittle about, but which they have taken up on trust from others, which have been palmed on their understandings by fraud or force, and which they continue to hold at the peril of life, limb, property, and character, with as little warrant from common sense in the first instance as appeal to reason in the last. The _ultima ratio regum_ proceeds upon a very different plea. Common sense is neither priestcraft nor state-policy. Yet ‘there’s the rub that makes absurdity of so long life;’ and, at the same time, gives the sceptical philosophers the advantage over us. Till nature has fair play allowed it, and is not adulterated by political and polemical quacks (as it so often has been), it is impossible to appeal to it as a defence against the errors and extravagances of mere reason. If we talk of common sense, we are twitted with vulgar prejudice, and asked how we distinguish the one from the other: but common and received opinion is indeed ‘a compost heap’ of crude notions, got together by the pride and passions of individuals, and reason is itself the thrall or manumitted slave of the same lordly and besotted masters, dragging its servile chain, or committing all sorts of Saturnalian licences, the moment it feels itself freed from it.—If ten millions of Englishmen are furious in thinking themselves right in making war upon thirty millions of Frenchmen, and if the last are equally bent upon thinking the others always in the wrong, though it is a common and national prejudice, both opinions cannot be the dictate of good sense: but it may be the infatuated policy of one or both governments to keep their subjects always at variance. If a few centuries ago all Europe believed in the infallibility of the Pope, this was not an opinion derived from the proper exercise or erroneous direction of the common sense of the people: common sense had nothing to do with it—they believed whatever their priests told them. England at present is divided into Whigs and Tories, Churchmen and Dissenters: both parties have numbers on their side; but common sense and party-spirit are two different things. Sects and heresies are upheld partly by sympathy, and partly by the love of contradiction: if there was nobody of a different way of thinking, they would fall to pieces of themselves.
