I said humans aren't particles, I probably should have said humans are more than just particles. Mort talks about the soul, I prefer to call it consciousness*. IMO, it's basically the same beast under either name, but for me "consciousness" has richer implications. It means that we are aware of the world around us, aware of our place in it, aware of our collective past and concerned for our future. It means that we look for patterns in chaos, we try to explain the inexplicable, we look for meaning for our existence and justifications for our actions. No other animal does this. Chimps and gorillas and other higher apes do some of the same things (I can't remember the exact data, but I remember reading that chimps will attach emotionally to dolls and other inanimate objects, to the point of associating meaning to them) but humans are the only species that have not only curiosity but awareness of all the things that exist in the world to be curious about. We're the only ones who ask "Why?"
So even though the same laws that govern quantum particles may also govern us, unlike the particles, we want those laws to have a point. We want there to be a reason. Science doesn't offer those kinds of reasons, it just tells us how things are. I am a great devotee of science, and do my best to keep abreast of all its developments, but my human consciousness still wants more.
I love whatifs, personally, and am always wondering how things might have been different if I'd made different choices. I like to try to pinpoint crucial points in my life and think "If I had done this instead of that, what would have resulted?" I don't believe that we are on preordained paths, but I like to think about the improbability of some things turning out the way they did. I like to marvel at the odds. That's what I mean by fate, that I did happen to make certain choices, which led to certain results. It is supremely illogical and the more I think about it the more it breaks down. But that's my way of imposing order on my random life.
