Happiness is a good flow of life.
A bad feeling is a commotion of the mind repugnant to reason, and against nature.
Better to trip with the feet than with the tongue
All things are parts of one single system, which is called nature; the individual life is good when it is in harmony with nature.
No evil is honorable: but death is honorable; therefore death is not evil.
Steel your sensibilities, so that life shall hurt you as little as possible.
