In proportion as we endeavor to live according to the guidance of reason, shall we strive as much as possible to depend less on hope, to liberate ourselves from fear, to rule fortune, and to direct our actions by the sure counsels of reason.

Let unswerving integrity be your watchword.

According as each has been educated, so he repents of or glories in his actions.
