Any magazine-cover hack can splash paint around wildly and call it a nightmare, or a witches sabbath or a portrait of the devil; but only a great painter can make such a thing really scare or ring true. That's because only a real artist knows the anatomy of the terrible, or the physiology of fear.
An isolated person requires correspondence as a means of seeing his ideas as others see them, and thus guarding against the dogmatisms and extravagances of solitary and uncorrected speculation. No man can learn to reason and appraise from a mere perusal of the writing of others.

For such an audience there is need neither of affectation nor of restraint. Sincerity is what they ask, detail, and volume; skill with the pen comes in conveniently, but brilliance is not necessary; genius is a hindrance even; and should you know your business and do it manfully, posterity will let you off mixing with great men, reporting famous affairs, or having lain with the first ladies in the land.
