He returned to Edinburgh in 1700, and remained there several years; during which time he first broached his great credit system, offering to supply the deficiency of coin by the establishment of a bank, which, according to his views, might emit a paper currency equivalent to the whole landed estate of the kingdom. His scheme excited great astonishment in Edinburgh; but, though the government was not sufficiently advanced in financial knowledge to detect the fallacies upon which it was founded, Scottish caution and suspicion served in the place of wisdom, and the project was rejected. Law met with no better success with the English Parliament; and the fatal affair of the death of Wilson still hanging over him, for which he had never been able to procure a pardon, he again went to France. The financial affairs of France were at this time in a deplorable condition. The wars, the pomp and profusion, of Louis XIV., and his religious persecutions of whole classes of the most industrious of his subjects, had exhausted his treasury, and overwhelmed the nation with debt. The old monarch clung to his selfish magnificence, and could not be induced to diminish his enormous expenditure; and his minister of finance was driven to his wits' end to devise all kinds of disastrous expedients to keep up the royal state, and to extricate the nation from its embarrassments. In this state of things, Law ventured to bring forward his financial project. It was founded on the plan of the Bank of England, which had already been in successful operation several years. He met with immediate patronage, and a congenial spirit, in the Duke of Orleans, who had married a natural daughter of the king. The duke had been astonished at the facility with which England had supported the burden of a public debt, created by the wars of Anne and William, and which exceeded in amount that under which France was groaning. The whole matter was soon explained by Law to his satisfaction. The latter maintained that England had stopped at the mere threshold of an art capable of creating unlimited sources of national wealth. The duke was dazzled with his splendid views and specious reasonings, and thought he clearly comprehended his system. Demarets, the Comptroller-General of Finance, was not so easily deceived. He pronounced the plan of Law more pernicious than any of the disastrous expedients that the government had yet been driven to. The old king also, Louis XIV., detested all innovations, especially those which came from a rival nation; the project of a bank, therefore, was utterly rejected. Law remained for a while in Paris, leading a gay and affluent existence, owing to his handsome person, easy manners, flexible temper, and a faro-bank which he had set up. His agreeable career was interrupted by a message from D'Argenson, Lieutenant-General of Police, ordering him to quit Paris, alleging that he was "_rather too skillful at the game which he had introduced_."
