Happiness.

True happiness is to understand our duties toward God and man;



... to enjoy the present, without anxious dependence on the future;



... not to amuse ourselves with either hopes or fears, but to rest satisfied with what we have, which is abundantly sufficient.



The time will come when diligent research over periods will bring to light things which now lie hidden.



Our universe is a sorry little affair unless it has something for every age to investigate as nature does not reveal her mysteries once and for all.
- Seneca
