Philosophy is Very Damaging

It is very damaging to learn any form of philosophy since it causes many questions and confusion. This then weaken a persons fear of punishment and in turn support his natural tendency to follow his desires and evil inclination. Therefore you will never find any person that became truly righteous and G-d fearing from studying books based on philosophy. Although these books do occasionally discus good traits etc., still their damage far outweighs any benefits they might have since they greatly confuse the mind of a person.
