The law, which was the business I designed to follow, appeared nauseous to me, and I could think of no other way of pushing my fortune in the world, but that of a scholar and philosopher.

I was infinitely happy in this course of life for some months; till at last, about the beginning of September, 1729, all my ardour seemed in a moment to be extinguished, and I could no longer raise my mind to that pitch, which formerly gave me such excessive pleasure." This "decline of soul" Hume attributes, in part, to his being smitten with the beautiful representations of virtue in the works of Cicero, Seneca, and Plutarch, and being thereby led to discipline his temper and his will along with his reason and understanding.
"I was continually fortifying myself with reflections against death, and poverty, and shame, and pain, and all the other calamities of life." And he adds very characteristically:-- "These no doubt are exceeding useful when joined with an active life, because the occasion being presented along with the reflection, works it into the soul, and makes it take a deep impression: but, in solitude, they serve to little other purpose than to waste the spirits, the force of the mind meeting no resistance, but wasting itself in the air, like our arm when it misses its aim." Along with all this mental perturbation, symptoms of scurvy, a disease now almost unknown among landsmen, but which, in the days of winter salt meat, before root crops flourished in the Lothians, greatly plagued our forefathers, made their appearance.

And, indeed, it may be suspected that physical conditions were, at first, at the bottom of the whole business; for, in 1731, a ravenous appetite set in and, in six weeks from being tall, lean, and raw-boned, Hume says he became sturdy and robust, with a ruddy complexion and a cheerful countenance--eating, sleeping, and feeling well, except that the capacity for intense mental application seemed to be gone.

He, therefore, determined to seek out a more active life; and, though he could not and would not "quit his pretensions to learning, but with his last breath," he resolved "to lay them aside for some time, in order the more effectually to resume them." The careers open to a poor Scottish gentleman in those days were very few; and, as Hume's option lay between a travelling tutorship and a stool in a merchant's office, he chose the latter.
"And having got recommendation to a considerable trader in Bristol, I am just now hastening thither, with a resolution to forget myself, and everything that is past, to engage myself, as far as is possible, in that course of life, and to toss about the world from one pole to the other, till I leave this distemper behind me."[3] But it was all of no use--Nature would have her way--and in the middle of 1736, David Hume, aged twenty-three, without a profession or any assured means of earning a guinea; and having doubtless, by his apparent vacillation, but real tenacity of purpose, once more earned the title of "wake-minded" at home; betook himself to a foreign country.
"I went over to France, with a view of prosecuting my studies in a country retreat: and there I laid that plan of life which I have steadily and successfully pursued.

I resolved to make a very rigid frugality supply my deficiency of fortune, to maintain unimpaired my independency, and to regard every object as contemptible except the improvement of my talents in literature."[4] Hume passed through Paris on his way to Rheims, where he resided for some time; though the greater part of his three years' stay was spent at La Fleche, in frequent intercourse with the Jesuits of the famous college in which Descartes was educated.
