Thomas De Quincey said this quote

Guilt and misery shrink, by a natural instinct, from public notice: they court privacy and solitude: and even in their choice of a grave will sometimes sequester themselves from the general population of the churchyard, as if declining to claim fellowship with the great family of man; thus, in a symbolic language universally understood, seeking (in the affecting language of Mr. Wordsworth)’ Humbly to expressA penitential loneliness.
