persuasion is the only motive of my present affection; which will either increase or diminish, according to your merit or demerit.  If you have the knowledge, the honor, and probity, which you may have, the marks and warmth of my affection shall amply reward them; but if you have them not, my aversion and indignation will rise in the same proportion; and, in that case, remember, that I am under no further obligation, than to give you the necessary means of subsisting.  If ever we quarrel, do not expect or depend upon any weakness in my nature, for a reconciliation, as children frequently do, and often meet with, from silly parents; I have no such weakness about me:  and, as I will never quarrel with you but upon some essential point; if once we quarrel, I will never forgive.  But I hope and believe, that this declaration (for it is no threat) will prove unnecessary.  You are no stranger to the principles of virtue; and, surely, whoever knows virtue must love it.  As for knowledge, you have already enough of it, to engage you to acquire more.  The ignorant only, either despise it, or think that they have enough:  those who have the most are always the most desirous to have more, and know that the most they can have is, alas! but too little.

Reconsider, from time to time, and retain the friendly advice which I send you.  The advantage will be all your own.

LETTER XXIII

London, December 29, O. S. 1747

Dear boy:  I have received two letters from you of the 17th and 22d, N. S., by the last of which I find that some of mine to you must have miscarried; for I have never been above two posts without writing to you or to Mr. Harte, and even very long letters.  I have also received a letter from Mr. Harte, which gives me great satisfaction:  it is full of your praises; and he answers for you, that, in two years more, you will deserve your manumission, and be fit to go into the world, upon a footing that will do you honor, and give me pleasure.

I thank you for your offer of the new edition of ‘Adamus Adami,’ but I do not want it, having a good edition of it at present.  When you have read that, you will do well to follow it with Pere Bougeant’s ’Histoire du Traite de Munster,’ in two volumes quarto; which contains many important anecdotes concerning that famous treaty, that are not in Adamus Adami.

You tell me that your lectures upon the ‘Jus Publicum’ will be ended at Easter; but then I hope that Monsieur Mascow will begin them again; for I would not have you discontinue that study one day while you are at Leipsig.  I suppose that Monsieur Mascow will likewise give you lectures upon the ‘Instrumentum Pacis,’ and upon the capitulations of the late emperors.  Your German will go on of course; and I take it for granted that your stay at Leipsig will make you a perfect master of that language, both as to speaking and writing;
