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 no age. The more we know, the more we feel our ignorance; the more we feel how much remains unknown.
- Humphrey Davy

Man masters nature not by force, but by understanding.
- Jacob Brownowski

    It can’t be Nature, for it is not sense.
    - Charles Churchill
