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

    Science is a mechanism, a way of trying to improve your knowledge of nature. It’s a system for testing your thoughts against the universe, and seeing whether they match.
    - Isaac Asimov

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

    Nature never says one thing, Wisdom another.

    God could cause us considerable embarrassment by revealing all the secrets of nature to us: we should not know what to do for sheer apathy and boredom.
    - Johann Wolfgang von Goethe

    To the dull mind all nature is leaden. To the illumined mind the whole world sparkles with light.

    American Natural History Museum: Milstein Hall of Advanced Mammals

    Sunday, September 28th, 2008

    When I look at the incredible wealth of biodiversity contained within just the class mammalia in its 164 million years of existence, it’s staggering what we don’t know. The immense number of species that weren’t preserved in the fossil record and stories that took place before homo sapiens arrived to witness them are fantastic example of Percy Bysshe Shelley’s observation, “The more we study, the more we discover our ignorance.”

    There are three principal means of acquiring knowledge. . . observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination.

    A human being is part of a whole, called by us the ‘Universe,’ a part limited in time and space. He experiences himself, his thoughts and feelings, as something separated from the rest–a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest us. Our task must be to free ourselves from this prison by widening our circles of compassion to embrace all living creatures and the whole of nature in its beauty.
    - Albert Einstein

    Human beings are part of nature. Anything they do is natural. It’s impossible for anything in nature to do anything unnatural.
