Letters of Abelard and Heloise, tr. John Hughes (London, 1776), II., Heloise to Abelard, 87-88:
If a picture, which is but a mute representation of an object, can give such pleasure, what cannot letters inspire? They have souls; they can speak; they have in them all that force which expresses the transports of the heart; they have all the fire of our passions; they can raise them as much as if the persons themselves were present; they have all the softness and delicacy of speech, and sometimes a boldness of expression even beyond it.

Letters were first invented for comforting such solitary wretches as myself. Having lost the substantial pleasures of seeing and possessing you, I shall in some measure compensate this loss by the satisfaction I shall find in your writing. There I shall read your most secret thoughts; I shall carry them always about me; I shall kiss them every moment: if you can be capable of any jealousy, let it be for the fond caresses I shall bestow on your letters, and envy only the happiness of those rivals. That writing may be no trouble to you, write always to me carelessly, and without study: I had rather read the dictates of the heart than of the brain. I cannot live if you do not tell me you always love me; but that language ought to be so natural to you, that I believe you cannot speak otherwise to me without great violence to yourself. And since, by that melancholy relation to your friend, you have awakened all my sorrows, it is but reasonable you should allay them by some marks of an inviolable love.
