A quote from Thomas Jefferson

The practice of morality being necessary for the well being of society, He [God] has taken care to impress its precepts so indelibly on our hearts that they shall not be effaced by the subtleties of our brain. We all agree in the obligation of the moral principles of Jesus and nowhere will they be found delivered in greater purity than in His discourses.

— Letter to James Fishback [September 27th, 1809]
