"Given the cause nature produces the effect..." - Quote by Leonardo Da Vinci

“Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory.”

“Art is the queen of all sciences communicating knowledge to all the generations of the world.”

“The eye which turns from a white object in the light of the sun and goes into a less fully lighted place will see everything as dark.”

“All things in nature work silently. They come into being and possess nothing. They fulfill their function and make no claim. All things alike do their work, and then we see them subside. When they have reached their bloom, each returns to its origin. . . . This reversion is an eternal law. To know that law is wisdom.”

“The world is emblematic. Parts of speech are metaphors, because the whole of nature is a metaphor of the human mind.”

“A healthy man, indeed, is the complement of the seasons, and in winter, summer is in his heart.”

“Why should I clutter my mind with general information when I have men around me who can supply any knowledge I need?”

“In business courtesy and efficiency have a symbiotic relationship.”

“There are some things you don’t have to know how it works – only that it works. While some people are studying the roots, others are picking the fruit. It just depends on which end of this you want to get in on." -- Jim Rohn”
