Philosophy is different from many other Arts subjects in that to study it you need to do it. But in both cases you will have to develop some of the skills used by the great practitioners. That's one of the reasons why philosophy can be such a rewarding subject to study. The word 'philosophy' is derived from the Greek for 'love of wisdom'. But that isn't particularly helpful in understanding how the word is used now.
Philosophy is a subject at the core of most humanities courses.
These very abstract questions can arise out of our everyday experience. Some people caricature philosophy as a subject with no relevance to life, a subject to be studied from an armchair for purely intellectual satisfaction, the academic equivalent of solving crossword puzzles. But this is a serious misrepresentation of large parts of the subject. For instance, the heated debate about whether boxing should be banned can only be answered by addressing important abstract questions. The analysis of reasons and arguments is a particular province of philosophy.
