percival lowell and the intranaut

An inscription on Percival Lowell's tomb at Lowell Observatory, Flagstaff is also true of the intranaut, the mystic, the explorer of the holocosmic: "Astronomy now demands bodily abstraction of its devotee... To see into the beyond requires purity... and the securing it makes him perforce a hermit from his kind... He must abandon cities and forego plains... Only in places above and aloof from men can he profitably pursue his search. He must learn to wait upon his opportunities and no less to wait for mankind's acceptance of his results... for in common with most explorers he will encounter on his return that final penalty of penetration - the certainty at first of being disbelieved."
