I am a determinist. To me, this means that I believe that, given a perfect snapshot of the position and momentum of every particle and subparticle in the entire universe, and also given infinite computing power and infinite time, it would be possible to extrapolate the history of the universe from start to finish. The problem with this, of course, is that you can't ever know the position and momentum of a particle.
Now, I will be the first to admit that I do not have the best grounding in Quantum Mechanics. But, it seems to me that what this says is that there will be a random component to any observation one can make, not that there will be a random component to anything that happens. And so, I believe that randomness is a property of observation, not a property of any event.
I mentioned this to my friend, M*, the other day and she asked "What about love?"
"Love is just a chemical reaction."
"A chemical reaction?"
"Well, a series of them." I thought for a moment about what else it could be. "Although, I suppose there are also nuclear reactions. Wouldn't it be funny if it turned out the feeling of 'love' was actually the transumation of lead into gold inside your heart?"
* I have to admit that I was somewhat hungover for this conversation and therefore the quotes are rough paraphrases at best. I apologize if I have misrepresented the gist of anything anyone may have said.
