In fact - uh-oh! Now you've done it. Now I'm going to present another of my weird ideas...
The light from different light bulbs exhibits different qualities - some are brighter, more bluish, maybe they flicker a bit, etc. This is a sort of super-simplified metaphor for how different human minds are. But a simple light bulb doesn't come anywhere near the multilayered complexity of a mind, so let's use a more complex metaphor instead - a television screen. Each pixel is sort of like an individual light bulb, but capable of changing colors and brightness, and a vast network of them work together to create images in motion. I guess this is analogous to neurons firing in a brain.
Now you could say, sticking with this metaphor, that 'it's nothing but a bunch of little spots changing colors'. But that would completely miss the fact that they change colors in a very complex fashion that creates not only coherent images in motion, but stories. Now those simple flashing pixels have created something of incredible complexity that goes way beyond 'just some flashing spots on a screen'. The story itself has complexities that no longer have anything to do with flashing spots of light, but rather with ideas - stories deal with things like loyalty and betrayal, love, hate, war, etc. Incredible that just some flashing spots on a screen can create something like that!
This is why I think it's pointless to discuss the mind in purely materialistic terms. Yes, in one sense it's nothing but electrical impulses across neurons and chemical reactions, but it creates something so far beyond that. Just discussing chemical reactions and electrical impulses doesn't even begin to come close to describing anything about the mind.
And when we talk about mental abilities, like the ability to make decisions, it involves the entirety of the mind. Decisions happen at the 'story' level (to go back to the TV analogy), not at any chemical or electrical level. So the self is a vastly complex entity consisting of layer upon layer of immaterial 'story stuff' (thoughts, ideas, memories, etc).
This 'story level stuff' is also where many of our influences exist. Some exist on more physical levels of course, like DNA.
One more metaphor if I may (and then I'll quit, promise! For this post anyway). To compare the mind and the body for purposes of clarification - the mind ingests and then digests influences at the mental level. Ideas and ideologies etc. These are some of the "influences" we've been discussing. For example, whether you're liberal or conservative, atheist or religious. This stuff all happens strictly on those deeply complex mental levels. So it's part of the gestalt - part of YOU. At least those influences that you've digested are part of you now. This goes back to my artist metaphor. We encounter influences - some of them we digest and like food they get broken down into constituent parts and used to build your growing gestalt. These influences now lose their discreet character - literally cease to exist as what they used to be and instead emerge as a part of you, modified beyond all recognition now. It's no longer 'the liberal influence you picked up from aunt Sally' - it's now 'the ever-growing and changing liberal attitude that you originally picked up from aunt Sally'.
Now, just like in your physical body - if you eat something and digest it your body breaks it down into nutrients and then uses them to supply growing cells - fully absorbed and digested and now something totally different from what it originally was.
So what I'm really saying is that - at some point your decisions are no longer affected simply by a bundle of discreet factors that aren't a part of you - but instead by influences that have been absorbed and ARE you now. So it really is YOU making the decisions.
Of course not all of your influencing factors are absorbed this way.
Ok, sorry for massive post.
