Humphry Davy

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.

Sir Humphry Davy (17 December 1778 – 29 May 1829), often incorrectly spelled Humphrey, was a Cornish chemist who discovered several chemical elements and studied the human body's response to electricity. He is generally credited with inventing the Miners' Safety Lamp, although George Stephenson also claimed the invention.

• Nothing is so fatal to the progress of the human mind as to suppose that our views of science are ultimate; that there are no mysteries in nature; that our triumphs are complete, and that there are no new worlds to conquer.

• 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.

• I envy no quality of the mind or intellect in others; not genius, power, wit, nor fancy; but, if I could choose what would be most delightful, and, I believe, most useful to me, I should prefer a firm religious belief to every other blessing.
