The name and writings of Mr Hume have been long since well known throughout Europe. At the same time, his personal acquaintance have remarked, in the candour and simplicity of his manners, that impartiality and ingenuousness of disposition which distinguishes his character, and is sufficiently indicated in his writings. He hath exerted those great talents he received from nature, and the acquisitions he made by study, in the search of truth, and promoting the good of mankind; never wasting his time, or sacrificing his repose, in literary or personal disputes. He hath seen his writings frequently censured with bitterness, by fanaticism, ignorance, and the spirit of party, without ever giving an answer to his adversaries. Even those who have attacked his works with the greatest violence, have always respected his personal character. His love of peace is so well known, that the criticisms written against his pieces, have been often brought him by their respective authors, for him to revise and correct them. At one time, in particular, a performance of this kind was shown to him, in which he had been treated in a very rude and even injurious manner; on remarking which to the author, the latter struck out the exceptionable passages, blushing and wondering at the force of that _polemic spirit_ which had carried him imperceptibly away beyond the founds of truth and decency. It was with great reluctance that a man, possessed of such pacific dispositions, could be brought to consent to the publication of the following piece. He was very sensible that the quarrels among men of letters are a scandal to philosophy; nor was any person in the world less formed for giving occasion to a scandal, so consolatory to blockheads. But the circumstances were such as to draw him into it, in spite of his inclinations. All the world knows that Mr Rousseau, proscribed in almost every country where he resided, determined at length to take refuge in England; and that Mr Hume, affected by his situation, and his misfortunes, undertook to bring him over, and to provide for him a peaceful, safe, and convenient asylum. But very few persons are privy to the zeal, activity, and even delicacy, with which Mr Hume conferred this act of benevolence. What an affectionate attachment he had contracted for this new friend, which humanity had given him! with what address he endeavoured to anticipate his desires, without offending his pride! in short, with what address he strove to justify, in the eyes of others, the singularities of Mr Rousseau, and to defend his character against those who were not disposed to think so favourably of him as he did himself.
