Baḥya ibn Paquda read to teach that even though students must first learn Tradition, they should not rely solely on Tradition if they are able to attain comprehension through reason. He therefore deduced that all who are capable are obligated to investigate with their intellect and to bring logical proofs of the Tradition by the demonstration that careful judgment would support. Baḥya also argued that the words of , "Do you thus repay the Lord, O foolish and unwise people?" apply to those who fail to reflect upon the obligation of the service of God.
