"It is the great fallacy of Dr. Mandeville's book to represent every passion as wholly vicious, which is so in any degree and in any direction. It is thus that he treats every thing as vanity which has any reference, either to what are, or to what ought to be the sentiments of others: and it is by means of this sophistry, that he establishes his favourite conclusion, that private vices are public benefits. If the love of magnificence, a taste for the elegant arts and improvements of human life, for whatever is agreeable in dress, furniture, or equipage, for architecture, statuary, painting, and music, is to be regarded as luxury, sensuality and ostentation, even in those whose situation allows, without any inconveniency, the indulgence of those passions, it is certain that luxury, sensuality, and ostentation are public benefits: since, without the qualities upon which he thinks proper to bestow such opprobrious names, the arts of refinement could never find encouragement, and must languish for want of employment. Some popular ascetic doctrines which had been current before his time, and which placed virtue in the entire extirpation and annihilation of all our passions, were the real foundation of this licentious system. It was easy for Dr. Mandeville to prove, first, that this entire conquest never actually took place among men; and, secondly, that if it was to take place universally, it would be pernicious to society, by putting an end to all industry and commerce, and in a manner to the whole business of human life. By the first of these propositions he seemed to prove that there was no real virtue, and that what pretended to be such, was a mere cheat and imposition upon mankind; and by the second, that private vices were public benefits, since without them no society could prosper or flourish."
