Louis Blanc writing about anonymous journalism in Letters on England, Vol. II, translated by James Hutton and L. J. Trotter (London: Samson Low, Son, and Marston, 1867), p. 169:

To shirk the moral responsability of one's words is a proceeding which cannot be reconcilable with the sentiment of personal dignity. The individual is badly protected where his reputation is exposed to darts hurled by an unknown hand; neither is it comfortable to the rules of fair play that a man should be authorised to conceal himself behind an impenetrable shrub, in order to fire thence, without peril, on his enemy as he passes.
