Not to know what has been transacted in former times 

is to be always a child. 

If no use is made of the labours of past ages, 

the world must remain always in the infancy of knowledge.

Neque porro quisquam est qui dolorem ipsum 

quia dolor sit amet, 

consectetur, 

adipisci velit. 

There is no one who loves pain itself, 

who seeks after it and wants to have it, 

simply because it is pain.

Gratitude is not only the greatest of virtues, 

but the parent of all the others.

The life of the dead 

is placed 

in the memory of the living.

The pursuit, even of the best things, ought to be calm and tranquil.

All action is of the mind 

and the mirror of the mind is the face, 

its index the eyes.

A room without books is like a body without a soul.
