Like many great Czechs before him, Havel insisted on the importance of truth, but with a difference. “Truth and love,” he was fond of saying, “must prevail over lies and hatred.” He was often ridiculed for what seemed like a Hallmark sentiment (“Why love?” people asked), but he defended the slogan by referring to one of his greatest insights: truth, by itself, is a malleable concept that depends for its truthfulness on who utters it, to whom it is said, and under what circumstances. As a playwright, Havel turned this insight into a dramatic device: in most of his plays, the main characters constantly lie to one another and to themselves, using words that, in other circumstances, would be perfectly truthful. Truth by itself is not enough: it needs a guarantor, someone to stand behind it. It must be uttered with no thought for gain, that is, in Havel’s words, with a love that seeks nothing for itself and everything for others. More here.
