The acquisition of knowledge is always of use to the intellect, because it may thus drive out useless things and retain the good. For nothing can be loved or hated unless it is first known.
I have wasted my hours.
Time stays long enough for anyone who will use it.
Where there is shouting, there is no true knowledge.
Just as courage is the danger of life, so is fear its safeguard.
Tears come from the heart and not from the brain.
