All are agreed, that the increase of learning and good morals are great blessings to society.
Without religion, I believe that learning does real mischief to the morals and principles of mankind.
While learning the language in France a young man's morals, health and fortune are more irresistibly endangered than in any country of the universe.
Learning never exhausts the mind.
Leonardo da Vinci
Morals are private. Decency is public.
