I believe his point is being backed up by you. You aren't making that choice. You simply must eat. He's saying everything is a product of inevitability.

I think this is inadequate. No longer is life just a bunch of particles bouncing back and forth. Besides, we can't even definitely prove any of this scientific stuff. Even if we think it's been proved, who knows? You know?

I think what SYG is saying is the same as what I am saying though if he said it better :P. I'll try my best. Basically we are evolved through yes, inevitability. However, that doesn't make us all products of that. We are now evolved to the point at which we do have the concious ability and power to make somewhat of a choice. No matter how small it is. Look at a cripple who takes his first step in 25 years. That's a BIG move for him, but small for us. So even though this might look grim, in that we have no choice... maybe the fact that I can either drink a glass of water or a glass of gatorade is incredibly profound.
