@AWohlfarth,
Purpose of philosophy is understand our life. The issue is everything has its limits.
Philosophy can repeat descriptions of life in so many ways. After that it repeats and rinse samething over and over with new labels and stories.
It does give general guideline. Does it help live life happy?. May be , May be not.
You can't live happy if your physical surrounding is bad. Sometimes even if you physical surrounding is good , you still can not be happy.
it is always "What is next?".
if you are poor you want money. if you are rich , you want drugs or what ever you think that makes you happy.
I really think philosophy helps you question things.
As long as you keep questioning things and not agreeing or disagreeing , you will grow.
