Philosophy is the subject which asks the largest and the ultimate of all questions in a search for first principles, as Plato would say "A philosopher is one who desires to discern the truth". It aims for an adequate interpretation of man and his place in reality. For Haz, the beginning of philosophy consist in when one has unexamined prejudices of the mind which has to be examined, the unexamined idols of the mind must be broken with this examination, the point is that there are so many things which are said in stone that are taken for granted which does not have to be. The 'unexamined prejudices' applies to dogmatic religious beliefs too.
