"I consider myself as very much honoured in being thought worthy of an answer by a person of so much merit; and as I find that the public does you justice with regard to the ingenuity and good composition of your piece, I hope you will have no reason to repent engaging with an antagonist, whom, perhaps, in strictness, you might have ventured to neglect. I own to you, that I never felt so violent an inclination to defend myself as at present, when I am thus fairly challenged by you, and I think I could find something specious at least to urge in my defence; but as I had fixed a resolution, in the beginning of my life, always to leave the public to judge between my adversaries and me, without making any reply, I must adhere inviolably to this resolution, otherwise my silence on any future occasion would be construed an inability to answer, and would be matter of triumph against me."[119:1] He then, in the passage already cited,[119:2] describes the occasion on which the "Theory of Miracles" was suggested to him. In answer to this, there is a letter by Campbell, in which he endeavours to rival his opponent in candour, politeness, and gentlemanlike feeling. The happy courtesy with which he apologizes for the occasionally irascible tone of his essay, shows that the retired northern divine possessed in no small degree the qualities that might have adorned a more showy station. DR. CAMPBELL _to_ HUME. _25th June, 1762._ The testimony you are pleased to give in favour of my performance, is an honour of which I should be entirely unworthy, were I not sensible of the uncommon generosity you have shown in giving it. Ever since I was acquainted with your works, your talents as a writer have, notwithstanding some differences in abstract principles, extorted from me the highest veneration. But I could scarce have thought that, in spite of differences of a more interesting nature, even such as regard morals and religion, you could ever force me to love and honour you as a man. Yet no religious prejudices (as you would probably term them,) can hinder me from doing justice to that goodness and candour, which appear in every line of your letter.
