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. Leonardo da Vinci
Nothing is more simple than greatness indeed, to be simple is to be great. Ralph Waldo Emerson
There is synthesis when, in combining therein judgments that are made known to us from simpler relations, one deduces judgments from them relative to more complicated relations. There is analysis when from a complicated truth one deduces more simple truths. André-Marie Ampère
