"To develop a complete mind: Study the science of art; Study the art of science. Learn how to see. Realize that everything connects to everything else."

"There are three classes of people: those who see, those who see when they are shown, those who do not see."

"Human subtlety will never devise an invention more beautiful, more simple or more direct than does nature, because in her inventions nothing is lacking and nothing is superfluous."

"Nature never breaks her own laws."

"Indeed, nature is full of infinite reasons that have never been in experience."
