My desire of being acquainted with celebrated men of every description, had made me, much about the same time, obtain an introduction to Dr. Samuel Johnson and to John Wilkes, Esq.  Two men more different could perhaps not be selected out of all mankind.  They had even attacked one another with some asperity in their writings; yet I lived in habits of friendship with both.  I could fully relish the excellence of each; for I have ever delighted in that intellectual chymistry, which can separate good qualities from evil in the same person.

Sir John Pringle, ‘mine own friend and my Father’s friend,’ between whom and Dr. Johnson I in vain wished to establish an acquaintance, as I respected and lived in intimacy with both of them, observed to me once, very ingeniously, ’It is not in friendship as in mathematicks, where two things, each equal to a third, are equal between themselves.  You agree with Johnson as a middle quality, and you agree with me as a middle quality; but Johnson and I should not agree.’  Sir John was not sufficiently flexible; so I desisted; knowing, indeed, that the repulsion was equally strong on the part of Johnson; who, I know not from what cause, unless his being a Scotchman, had formed a very erroneous opinion of Sir John.  But I conceived an irresistible wish, if possible, to bring Dr. Johnson and Mr. Wilkes together.  How to manage it, was a nice and difficult matter.

My worthy booksellers and friends, Messieurs Dilly in the Poultry, at whose hospitable and well-covered table I have seen a greater number of literary men, than at any other, except that of Sir Joshua Reynolds, had invited me to meet Mr. Wilkes and some more gentlemen on Wednesday, May 15.  ’Pray (said I,) let us have Dr. Johnson.’—­’What with Mr. Wilkes? not for the world, (said Mr. Edward Dilly:) Dr. Johnson would never forgive me.’—­’Come, (said I,) if you’ll let me negotiate for you, I will be answerable that all shall go well.’  Dilly.  ’Nay, if you will take it upon you, I am sure I shall be very happy to see them both here.’

Notwithstanding the high veneration which I entertained for Dr. Johnson, I was sensible that he was sometimes a little actuated by the spirit of contradiction, and by means of that I hoped I should gain my point.  I was persuaded that if I had come upon him with a direct proposal, ’Sir, will you dine in company with Jack Wilkes?’ he would have flown into a passion, and would probably have answered, ’Dine with Jack Wilkes, Sir!  I’d as soon dine with Jack Ketch.’  I therefore, while we were sitting quietly by ourselves at his house in an evening, took occasion to open my plan thus:—­’Mr. Dilly, Sir, sends his respectful compliments to you, and would be happy if you would do him the honour to dine with him on Wednesday next along with me, as I must soon go to Scotland.’  Johnson.  ‘Sir, I am obliged to Mr. Dilly.  I will wait upon him—­’ Boswell.  ’Provided, Sir, I suppose, that the company which
