It is allowed that vocations and employments of least dignity are of the most apparent use; that the meanest artizan or manufacturer contributes more to the accommodation of life, than the profound scholar and argumentative theorist; and that the publick would suffer less present inconvenience from the banishment of philosophers than from the extinction of any common trade. Some have been so forcibly struck with this observation, that they have, in the first warmth of their discovery, thought it reasonable to alter the common distribution of dignity, and ventured to condemn mankind of universal ingratitude. For justice exacts, that those by whom we are most benefited should be most honoured. And what labour can be more useful than that which procures to families and communities those necessaries which supply the wants of nature, or those conveniencies by which ease, security, and elegance, are conferred? This is one of the innumerable theories which the first attempt to reduce them into practice certainly destroys. If we estimate dignity by immediate usefulness, agriculture is undoubtedly the first and noblest science; yet we see the plough driven, the clod broken, the manure spread, the seeds scattered, and the harvest reaped, by men whom those that feed upon their industry will never be persuaded to admit into the same rank with heroes, or with sages; and who, after all the confessions which truth may extort in favour of their occupation, must be content to fill up the lowest class of the commonwealth, to form the base of the pyramid of subordination, and lie buried in obscurity themselves, while they support all that is splendid, conspicuous, or exalted. It will be found upon a closer inspection, that this part of the conduct of mankind is by no means contrary to reason or equity. Remuneratory honours are proportioned at once to the usefulness and difficulty of performances, and are properly adjusted by comparison of the mental and corporeal abilities, which they appear to employ. That work, however necessary, which is carried on only by muscular strength and manual dexterity, is not of equal esteem, in the consideration of rational beings, with the tasks that exercise the intellectual powers, and require the active vigour of imagination or the gradual and laborious investigations of reason.
