Live your life as though your every act were to become a universal law.

Morality is not the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.

It is beyond a doubt that all our knowledge begins with experience.

Live your life as though your every act were to become a universal law.

The law does not expect a man to be prepared to defend every act of his life which may be suddenly and without notice alleged against him

Two things fill the mind with renewed and increasing awe and reverence the more often and the more steadily that they are meditated on: the starry skies above me and the moral law inside me. I have not to search for them and conjecture them as though they were veiled in darkness or were in the transcendent region beyond my horizon; I see them before me and connect them directly with the consciousness of my existence
