Among the Scottish gentry of Hume's day, there were many men of high education and accomplishments; and the glimpses we occasionally obtain into the society which he frequented, show us a circle possessing a much less provincial tone than later times would probably have exhibited in the same class. The notion that a university was a seat of learning, where the scholarship of all the world should meet, and not a provincial school, still lingered in our country, and prompted the gentry to educate their sons abroad. In the sixteenth and seventeenth centuries, the registers of the universities of Paris, Bourgès, Bologna, and Leyden, were crowded with familiar Scottish names, whom we find holding as great a proportion among the teachers as among the learners; and thus a Wilson, a Barclay, a Bellenden, a Jack, and many others, whose fame hardly reached their native country, are conspicuous among the literary ornaments of the foreign universities. It is perhaps in a great measure to the lingering continuance of this practice through part of the eighteenth century, that we may attribute the learning and accomplishments of the society in Scotland during that period.[151:1] "Many are poets who have never penned their inspiration, and perchance the best." Many also are philosophers who have never either penned their philosophy, or put it into shape in their own minds. The two operations of induction and analysis proceed in every human mind with more or less success; but it is only when literary ambition, or pecuniary necessity, or the desire to head a system, prompts a man to collect and put into shape their results, that they are given to the world. Instances have occurred in which they have appeared very nearly in their raw unwrought form. Thus, Tucker's "Light of Nature" is nothing more than the reflections of an English country gentleman, collected and strung together. Paley and Reid used them as if they had themselves gone through the operation, and put the results into shape; while the late William Hazlitt was at the pains of writing an abridgment of the book. It was fortunate for philosophy that these disconnected observations and thoughts were collected and preserved. And the reflection leads to the recollection of the quantity of valuable thoughts that any man, who notices the course of conversation around him, hears produced and dropped. In after-dinner social intercourse, in general verbal criticism of books or men, how much of the gold of true philosophy is scattered away with the dross; lost almost at the moment it is uttered, and forgotten both by hearer and speaker.
