not appear extraordinary from so great a city to so famous a teacher, who taught, too, what was at that time the most fashionable of all sciences, rhetoric. He must have made, therefore, by each course of lectures, a thousand minæ, or L.3333 : 6 : 8. A thousand minæ, accordingly, is said by Plutarch, in another place, to have been his didactron, or usual price of teaching. Many other eminent teachers in those times appear to have acquired great fortunes. Georgias made a present to the temple of Delphi of his own statue in solid gold. We must not, I presume, suppose that it was as large as the life. His way of living, as well as that of Hippias and Protagoras, two other eminent teachers of those times, is represented by Plato as splendid, even to ostentation. Plato himself is said to have lived with a good deal of magnificence. Aristotle, after having been tutor to Alexander, and most munificently rewarded, as it is universally agreed, both by him and his father, Philip, thought it worth while, notwithstanding, to return to Athens, in order to resume the teaching of his school. Teachers of the sciences were probably in those times less common than they came to be in an age or two afterwards, when the competition had probably somewhat reduced both the price of their labour and the admiration for their persons. The most eminent of them, however, appear always to have enjoyed a degree of consideration much superior to any of the like profession in the present times. The Athenians sent Carneades the academic, and Diogenes the stoic, upon a solemn embassy to Rome; and though their city had then declined from its former grandeur, it was still an independent and considerable republic. Carneades, too, was a Babylonian by birth; and as there never was a people more jealous of admitting foreigners to public offices than the Athenians, their consideration for him must have been very great. This inequality is, upon the whole, perhaps rather advantageous than hurtful to the public. It may somewhat degrade the profession of a public teacher; but the cheapness of literary education is surely an advantage which greatly overbalances this trifling inconveniency. The public, too, might derive still greater benefit from it, if the constitution of those schools and colleges, in which education is carried on, was more reasonable than it is at present through the greater part of Europe. Thirdly, the policy of Europe, by obstructing the free circulation of labour and stock, both from employment to employment, and from place to place, occasions, in some cases, a very inconvenient inequality in the whole of the advantages and disadvantages of their different employments. The statute of apprenticeship obstructs the free circulation of labour from one employment to another, even in the same place. The exclusive privileges of corporations obstruct it from one place to another, even in the same employment.
