Happiness resides not in possessions and not in gold, the feeling of happiness dwells in the soul. -Democritus.

Happiness does not reside in strength or money; it lies in rightness and many-sidedness

It is godlike ever to think on something beautiful and on something new.

It is greed to do all the talking but not to want to listen at all.

I would rather discover one true cause than gain the kingdom of Persia.

By convention sweet and by convention bitter, by convention hot, by convention cold, by convention color; but in reality atoms and void.
