The acquisition of true knowledge normally leads to humility when approached in a sincere manner. One who acquires true knowledge realises how little they know. However, when it is approached in a materialistically restricted manner, it causes people to become proud. This flawed approach to seeking knowledge is not something new, and has precedents from others who have lived in former ages:
"Then when their Messengers came to them with clear proofs, they were glad (and proud) with that which they had of the knowledge (of worldly things): And that at which they used to mock, surrounded them (i.e. the punishment)." (Soorah Ghaafir, 40:83)
