a lesson "Where were we from?where will we go to ? And who are we?" My teacher inquired us students who are interested in Philosophy but knew nothing about this matter. She told us that those are famous problems which ever baffled many philosophiers.Honestly speaking,as an university student who ever were proud of my konwledge,I could hardly answer those qusetion then and at present of course. Nevertheless,I believe that I will know the keys in the future if I read books as well as do meaningful things constantly.Because philosophy means "love wisdom",undoubtedly,it excists in books and deeds.
