Michalis Koumbios, Danielle Louise AdamopoulosPLATO

There is no harm in repeating a good thing

Ideas are the source of all things

Knowledge becomes evil if the aim be not virtuous

No one is more hated than he who speaks the truth

Necessity is the mother of invention

Opinion is the medium between knowledge and ignorance

If a man neglects education, he walks lame to the end of his life
