@kennethamy,
Quote:We were unaware of Gravity for a large portion of our history, did it not motivate everything to fall when dropped both when we knew of it and not?
That's all fine, but, if you wanted to apply it to my argument, this is a false analogy. We are asking about motivation - we CAN act selfishly, I do not dispute this, in fact I think we generally do, whether we know it or not. None the less, if one's motivation is selfless, even if the action benefits the agent, the motivation remains selfless.
Can you, with any certainty, determine my motivations for an action?
I've read the Twain, and concluced long ago he is no philosopher. Smart? No, he's brilliant. A brilliant writer. I do not read Thoreau as a philosophical treatise, nor should I. The same holds for Twain.
Quote:I do not think that selfishness as people would act selfishly (stealing the last gobstopper) applies any of its meaning to the inherent selfishness of action.
It doesn't have to. The argument does not rely on such a thin view of selfishness.
Quote:For something to be selfless, one would think it would need to be done without knowledge of any positive reprecussions that could come from it, and with probable knowledge that in fact, negative reprecussions will come from it.
And here is, what seems to be, the primary misunderstanding. This claim is simply not the case. Even if some positive reprecussions are known, if the motivation for the action is not selfish, the action is not selfish.
