Edith Wharton

There are two ways of spreading light: to be the candle or the mirror that reflects it.

Source: "Vesalius in Zurich" (poem), Edith Wharton, 1902

Authentically Wharton; the standard citation is her dramatic monologue 'Vesalius in Zurich' (1902), which I recall as the source of the candle-and-mirror lines. Confidence is high on Wharton, good but not certain on the poem and date, so this stays at 'attributed'. The line is sometimes trimmed or reworded in circulation.

One can remain alive long past the usual date of disintegration if one is unafraid of change, insatiable in intellectual curiosity, interested in big things, and happy in small ways.

Source: A Backward Glance, Edith Wharton, 1934

From Wharton's memoir A Backward Glance (1934), in her reflections on aging — this is the citation consistently given and it matches my recollection of the book. Confident in the source; no page verified.
