“Love betters what is best”

Source: The History of Pendennis (1848-1850), Ch. 6.
Context: It is best to love wisely, no doubt; but to love foolishly is better than not to be able to love at all. Some of us can't: and are proud of our impotence, too.

Introduction to The Golden Man (1980)
Context: Several years ago, when I was ill, Heinlein offered his help, anything he could do, and we had never met; he would phone me to cheer me up and see how I was doing. He wanted to buy me an electric typewriter, God bless him — one of the few true gentlemen in this world. I don't agree with any ideas he puts forth in his writing, but that is neither here nor there. One time when I owed the IRS a lot of money and couldn't raise it, Heinlein loaned the money to me. I think a great deal of him and his wife; I dedicated a book to them in appreciation. Robert Heinlein is a fine-looking man, very impressive and very military in stance; you can tell he has a military background, even to the haircut. He knows I'm a flipped-out freak and still he helped me and my wife when we were in trouble. That is the best in humanity, there; that is who and what I love.
