All Sorrow Has Its Root In Man's

To Go Beyond The Bounds Of Moderation Is To Outrage Humanity. The Greatness Of The Human Soul Is Shown By Knowing How To Keep Within Proper Bounds. There Are Two Equally Dangerous Extremes- To Shut Reason Out, And Not To Let Nothing In.

Let Us Now Speak According To Natural Lights. If There Is A God, He Is Infinitely Incomprehensible. . . . We Are Then Incapable Of Knowing Of Either What He Is Or If He Is. . . .

Unless We Love The Truth We Cannot Know It.

We Know The Truth Not Only Through Our Reason But Also Through Our Heart. It Is Through The Latter That We Know First Principles, And Reason, Which Has Nothing To Do With It, Tries In Vain To Refute Them.

One Must Know Oneself. If This Does Not Serve To Discover Truth, It At Least Serves As A Rule Of Life And There Is Nothing Better.
