Philosophy: Who Doesn't Need It?

Who doesn't need philosophy?

People who have the world figured out don't need it.  If you know what's up when it comes to God and the soul, the meaning of life, the content and basis of morality, the role of state, and so on, then you certainly don't need philosophy.  If you are a Scientologist or a Mormon or a Roman Catholic or an adherent of any other religious or quasi-religious worldview then you have your answers and philosophy as inquiry (as opposed to philosophy as worldview) is strictly unnecessary.  And same goes for the adherents of such nonreligious worldviews as leftism and scientism and evangelical atheism. 

He who has the truth needn't seek it.  And those  who are in firm possession of the truth are well-advised to stay clear of philosophy with its tendency to sow the seeds of doubt  and confusion.

Those who are secure in their beliefs are also well-advised to turn a blind eye to the fact of the multiplicity of conflicting worldviews.  Taking that fact into cognizance may cause them to doubt whether their 'firm possession of the truth' really is such.
