Life is too precious to be spent in this weaving and unweaving of false impressions, and it is better to live quietly under some degree of misrepresentation than to attempt to remove it by the uncertain process of letter-writing.
A man who publishes his letters becomes a nudist -- nothing shields him from the world's gaze except his bare skin. A writer, writing away, can always fix himself up to make himself more presentable, but a man who has written a letter is stuck with it for all time.
A short letter to a distant friend is, in my opinion, an insult like that of a slight bow or cursory salutation -- a proof of unwillingness to do much, even where there is a necessity of doing something.
In a man's letters you know, Madam, his soul lies naked, his letters are only the mirror of his breast, whatever passes within him is shown undisguised in its natural process. Nothing is inverted, nothing distorted, you see systems in their elements, you discover actions in their motives.
Letters are above all useful as a means of expressing the ideal self; and no other method of communication is quite so good for this purpose. In letters we can reform without practice, beg without humiliation, snip and shape embarrassing experiences to the measure of our own desires...
How frail and ephemeral is the material substance of letters, which makes their very survival so hazardous. Print has a permanence of its own, though it may not be much worth preserving, but a letter! Conveyed by uncertain transportation, over which the sender has no control; committed to a single individual who may be careless or inappreciative; left to the mercy of future generations, of families maybe anxious to suppress the past, of the accidents of removals and house-cleanings, or of mere ignorance. How often it has been by the veriest chance that they have survived at all.
