Some people make it a question, whether is the greatest delight, the enjoying of an old friendship, or the acquiring of a new one? but it is in the preparing of a friendship, and in the possession of it, as it is with the husbandman in sowing and reaping; his delight is the hope of his labor in the one case, and the fruit of it in the other. My conversation lies among my books, but yet in the letters of a friend, methinks I have his company; and when I answer them, I do not only write, but speak: and, in effect, a friend is an eye, a heart, a tongue, a hand, at all distances. When friends see one another personally, they do not see one another as they do when they are divided, where the meditation dignifies the prospect; but they are effectually in a great measure absent even when they are present. Consider their nights apart, their private studies, their separate employments, and necessary visits; and they are almost as much together divided as present. True friends are the whole world to one another; and he that is a friend to himself is also a friend to mankind. Even in my very studies, the greatest delight I take in what I learn is the teaching of it to others; for there is no relish, methinks, in the possession of anything without a partner; nay, if wisdom itself were offered me upon condition only of keeping it to myself, I should undoubtedly refuse it.
