Bluejay: I would like to apologize. I never go into debates with the intention of personally offending anyone, and I hope that you don't either. I let my offense to your previous statement toward homosexuals take over my thoughts, and so I jumped to the "hatred" conclusion, when I know that that is not necessarily the case. For that I'm sorry, I never meant to offend you, and I hope that your offense won't prevent you from reading my argument.
I've written two messages to you, and in that time you've managed to turn "there are multiple motivations" into "motivation is not required"...
You misinterpret what I was trying to say here. I was trying to say that
if someone were to say "I'm going to do a good deed for the hell of it," it
would be the equivalent of saying "I think I'll go outside, spin 3 times, suck on a rock for a bit, then place it back on the ground." What I'm saying is that there
must be a motivation for an act. That can only necessarily be one thing: the seeking of pleasure (subconsciously). I know you think there could be multiple motivations, but I'll explain why I don't think that could be the case (getting down to the nitty gritty of things):
Our brain has sensory input. That sensory input, as far as I know, can only be interpreted as "pleasure" or "pain", or "good" or "bad". This duality is fundamental. If something coming into our brains is interpreted as "good", we try to keep it that way. If something is interpreted as "bad", we try to right it, make it "good" (as interpreted by our own individual brains. In other words, avoid an aversive stimulus). Therefore if we interpret something out there as needing righting, we do a good deed, and make it "good" in our minds. The seeking of "goodness" is, and can be, the only motivation for doing an action of any sort. Our brain doesn't know of anything but itself, so it can only interpret something as bad, and try to make it good again. Decrease the amount of aversive stimuli, and/or increase the amount of appetitive stimuli.
Now, considering the possibility of another motivation other than making something "bad", "good" again. This other motivation would have to be some other force out there making the neurons in our brain fire and making us do a good deed, besides pain or pleasure. I can think of no such force, which is why I've been lead to this conclusion.
