One swallow does not make a summer,neither does one fine day... - Aristotle, The Nicomachean Ethics

"With the truth, all given facts harmonize; but with what is false, the truth soon hits a wrong note."

"For the things we have to learn before we can do them, we learn by doing them."

"For the things we have to learn before we can do them, we learn by doing them."

"One swallow does not make a summer,neither does one fine day; similarly one day or brief time of happiness does not make a person entirely happy."

"The pleasures arising from thinking and learning will make us think and learn all the more. 1153a 23"
