Clarity

From Anecdotal Evidence, a quote about clarity:

Primo Levi: “On Obscure Writing” (Other People’s Trades (trans. Raymond Rosenthal, 1989): “He who does not know how to communicate, or communicates badly, in a code that belongs only to him and a few others, is unhappy, and spreads unhappiness around him. If he communicates badly deliberately, he is wicked or at least a discourteous person.”
