Poetry Quotes (page 5)
Poetry, if it is not to be a lifeless repetition of forms, must be constantly exploring "the frontiers of the spirit." But these frontiers are not like the surveys of geographical explorers, conquered once for all and settled. The frontiers of the spirit are more like the jungle which, unless continuously kept under control, is always ready to encroach and eventually obliterate the cultivated area.
T. S. Eliot
