Study without desire spoils the memory, and it retains nothing that it takes in
Italian polymath of the Renaissance whose areas of interest included invention, drawing, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography.
There is no friend as loyal as a book
People who say it cannot be done should not interrupt those who are doing it
From a small seed a mighty trunk may grow.
Never ruin an apology with an excuse
I am the wisest man alive, for I know one thing, and that is that I know nothing
Beauty is no quality in things themselves: It exists merely in the mind which contemplates them; and each mind perceives a different beauty
