"We should venture on the study of..." - Quote by Aristotle

“People generally despise where they flatter.”

“The mathematical sciences particularly exhibit order symmetry and limitations; and these are the greatest forms of the beautiful.”

“Some kinds of animals burrow in the ground; others do not. Some animals are nocturnal, as the owl and the bat; others use the hours of daylight. There are tame animals and wild animals. Man and the mule are always tame; the leopard and the wolf are invariably wild, and others, as the elephant, are easily tamed.”

“In the production of the necessaries of life Nature is ready enough to assist man.”

“Nature's first green is gold.”

“There is more evidence to prove that saltness [of the sea] is due to the admixture of some substance, besides that which we have adduced. Make a vessel of wax and put it in the sea, fastening its mouth in such a way as to prevent any water getting in. Then the water that percolates through the wax sides of the vessel is sweet, the earthy stuff, the admixture of which makes the water salt, being separated off as it were by a filter.”

“Darwin has interested us in the history of nature's technology.”

“Everybody should be ashamed who uses the wonders of science and engineering without thinking and having mentally realized not more of it than a cow realizes of the botany of the plants which it eats with pleasure.”

“My scientific work is motivated by an irresistible longing to understand the secrets of nature not by other feelings.”
