A private teacher could never find his account in teaching either an exploded and antiquated system of a science acknowledged to be useful, or a science universally believed to be a mere useless and pedantic heap of sophistry and nonsense. Such systems, such sciences, can subsist nowhere, but in those incorporated societies for education whose prosperity and revenue are in a great measure independent of their reputation and altogether independent of their industry. Were there no public institutions for education, a gentleman, after going through with application and abilities the most complete course of education which the circumstances of the times were supposed to afford, could not come into the world completely ignorant of everything which is the common subject of conversation among gentlemen and men of the world.
