“One of the duties of old-age, is the management of time. The less that remains to us, the more valuable we ought to consider it.”

Context: The less important an issue is, the more time managers spend discussing it. More time is spent on small talk than is spent on large talk. Most talk is about what matters least. What matters least is what most of us know most about.

Discourse Delivered at the Royal Society (30 November 1825), published in Six Discourses delivered before the Royal Society, at their Anniversary Meetings, on the Award of the Royal and Copley Medals, preceded by an Address to the Society on the Progress and Prospects of Science (1827); also in The Edinburgh Review Or Critical Journal (October 1827)
Context: Fortunately science, like that nature to which it belongs, is neither limited by time nor by space. It belongs to the world, and is of no country and of no age. The more we know, the more we feel our ignorance; the more we feel how much remains unknown; and in philosophy, the sentiment of the Macedonian hero can never apply, — there are always new worlds to conquer.
