"Why is it that all en do not adhere to truth, instead of believing in falsehood? The cause seemed to be the nature of man which is weak and sluggish. Man aspires to know the truth and the hidden things of nature, but this endeavor is difficult and only be attained with great labor and patience.. hence people hastily accept what they have heard from their fathers and shy away from critical examination. But God created man to be a master of his own actions, so that he will be what he wills to be, good or bad."
Zara Yacob, 15th century Ethiopian philosopher and the Descartes of Medieval Ethiopia
