Learning never exhausts the mind.
Milan
An investment in knowledge pays the best interest.
I do not think much of a man who is not wiser today than he was yesterday.
Education is the kindling of a flame, not the filling of a vessel.
As a well-spent day brings happy sleep, so a life well spent brings happy death.
Study without desire spoils the memory, and it retains nothing that it takes in.
The noblest pleasure is the joy of understanding.
