Who has known heights and depths shall not again know peace – not as the calm heart knows low lived walls; a garden close. And though he tread the humble ways of men, he shall not speak the common tongue again. Who has known heights shall bear forever more, an incommunicable thing that hurts his heart, as if a wing beat at the portal, challenging; And yes-lured by the gleam his vision wore – Who once has trodden stars seeks peace no more. – Mary Brent Whiteside, “Who Has Known Heights,”v 1936.
