Hi michel,
Its not really that they change so easily, but rather, I have this tendency (for good or for bad) to leave something that I already enjoy in search of something better. It seems to me that there's always something more interesting behind door number 2. I'm glad I don't do drugs. (I tried, and decided that a sober consciousness was better.) Why I do this, I have no clue. Maybe its because of my perfectionist nature, or my neurotic tendencies. Maybe its because I don't understand what it means to be truly interested in something, to have a hobby (whatever that is).
As for my religious beliefs, its a harder question, one which I haven't been able to fathom for myself. Although I have nothing against those who employ the mix-and-match approach to religious doctrines, I have reservations against doing it myself. (But isn't this really the only option we have left in a postmodern, pluralistic world? "We are all heretics," says one religious scholar, I forget his name. Heresy, deriving from the Greek for "to choose"). I have jumped from many a religion to another, surveying and comparing, picking out aspects I liked and those I didn't. So I guess that by what I said I meant that I change between religions, the established institutions themselves. And only recently I figured that doing this wouldn't answer any questions for me. Not until I actually start believing. It doesn't matter in what or in whom. Well, I guess it does, but that isn't my primary concern. I need to know what believing is. What does a devout believer mean when he/she says "I believe in such and such"? And how do you know what belief is unless you already believe? Can you really say you know what happiness is unless you've felt it? (I won't even get into sensory experience, there's nothing in the world that's any more deceptive). And if that doesn't make you give up, religious mystics talk of a "knowing" that is different from any conventional forms of knowledge. And I ask.. "OK, so what IS IT? and HOW do you get it?" I lose myself in frustration.
This is where you go :banghead3 !
Sorry to have answered your questions with a hundred others. I have no answers, only more questions.
Hope to see you around.
