There does not exist a category of science to which one can give the name applied science. There are science and the applications of science, bound together as the fruit of the tree which bears it.
Louis Pasteur

Through the small tall bathroom window the December yard is gray and scratchy, the tree calligraphic.
Dave Eggers

'Tis education forms the common mind; just as the twig is bent the tree's inclined.
Alexander Pope

To campaign against colonialism is like barking up a tree that has already been cut down.
Andrew Cohen

Unless a tree has borne blossoms in spring, you will vainly look for fruit on it in autumn.
Walter Scott

We are a generation of settlers, and without the steel helmet and gun barrel, we shall not be able to plant a tree or build a house.
Moshe Dayan

We are born believing. A man bears beliefs as a tree bears apples.
Ralph Waldo Emerson

We are separated from God on two sides; the Fall separates us from Him, the Tree of Life separates Him from us.
Franz Kafka

We are sinful not only because we have eaten of the Tree of Knowledge, but also because we have not yet eaten of the Tree of Life. The state in which we are is sinful, irrespective of guilt.
Franz Kafka

We could not guard every water pipeline from being blown up and every tree from being uprooted. We could not prevent every murder of a worker in an orchard or a family in their beds.
Moshe Dayan

We ought to think that we are one of the leaves of a tree, and the tree is all humanity. We cannot live without the others, without the tree.
Pablo Casals

We smile at the ignorance of the savage who cuts down the tree in order to reach its fruit; but the same blunder is made by every person who is over eager and impatient in the pursuit of pleasure.
William Ellery Channing

We will all, someday, experience death, and become obsolete as a dead leaf falling from a tree, crushed by passersby to ashes underlying the earth.
Kim Elizabeth

Jean Genet

Jay Inslee

What is more mortifying than to feel that you have missed the plum for want of courage to shake the tree?
Logan P. Smith

What is the meaning of the togetherness of the perceiving mind, in that peculiar modification of perceiving which makes it perceive not a star but a tree, and the tree itself, is a problem for philosophy.
Samuel Alexander

What is the purpose of the giant sequoia tree? The purpose of the giant sequoia tree is to provide shade for the tiny titmouse.
Edward Abbey

Whatever I do is done out of sheer joy; I drop my fruits like a ripe tree. What the general reader or the critic makes of them is not my concern.
Henry Miller

When I am finishing a picture, I hold some God-made object up to it - a rock, a flower, the branch of a tree or my hand - as a final test. If the painting stands up beside a thing man cannot make, the painting is authentic. If there's a clash between the two, it's bad art.
Marc Chagall
