“Most of the arts and professions in a state,” says by far the most illustrious philosopher and historian of the present age, “are of such a nature, that, while they promote the interests of the society, they are also useful or agreeable to some individuals; and, in that case, the constant rule of the magistrate, except, perhaps, on the first introduction of any art, is, to leave the profession to itself, and trust its encouragement to the individuals who reap the benefit of it. The artizans, finding their profits to rise by the favour of their customers, increase, as much as possible, their skill and industry; and as matters are not disturbed by any injudicious tampering, the commodity is always sure to be at all times nearly proportioned to the demand.
“But there are also some callings which, though useful and even necessary in a state, bring no advantage or pleasure to any individual; and the supreme power is obliged to alter its conduct with regard to the retainers of those professions. It must give them public encouragement in order to their subsistence; and it must provide against that negligence to which they will naturally be subject, either by annexing particular honours to profession, by establishing a long subordination of ranks, and a strict dependence, or by some other expedient. The persons employed in the finances, fleets, and magistracy, are instances of this order of men.
“It may naturally be thought, at first sight, that the ecclesiastics belong to the first class, and that their encouragement, as well as that of lawyers and physicians, may safely be entrusted to the liberality of individuals, who are attached to their doctrines, and who find benefit or consolation from their spiritual ministry and assistance. Their industry and vigilance will, no doubt, be whetted by such an additional motive; and their skill in the profession, as well as their address in governing the minds of the people, must receive daily increase, from their increasing practice, study, and attention.
