“Avoid a frontal attack on a long established position; instead, seek to turn it by flank movement, so that a more penetrable side is exposed to the thrust of truth. But, in any such indirect approach, take care not to diverge from the truth-for nothing is more fatal to its real advancement than to lapse into untruth.”
