Ask questions stubbornly, very proud men who seeing themselves right without knowing anything about the matter. This shows lack of piety, a tendency to ranting, a weak mind, and excessive vanity. [...] If you hear, or read writing (you object to), do not react with violence until you have proof that what is expressed is wrong. Do not accept that with the enthusiasm of the credulous man either until being wholly convinced of that. In both situations you blind yourself and drift away from truth... Act like a person who has no preconceived views, one ready to know and accept what is right and reject what is wrong.
