There is a paradox about philosophy: it is both everywhere and nowhere.
Philosophy is everywhere because each of us, throughout life, confronts philosophical issues. Whether these be of the urgent variety ('Would it be wrong to steal a kiss?') or,instead, of the kind that quietly ties your mind in knots while you lie in bed ('If God knows everything, then am I free to decide when to get up?'), philosophical questions are our constant companions. From nursery to nursing home, we never cease to think and talk about philosophical issues. It may be doubtful how sapient humans actually are, but it is not debatable how unstoppably philosophical we are: our species would have been better named Homo philosophicus.
