Do you have an instance of "I proactively do X" where you do not class it as reactive? Do you have an instance of "I wish to avoid Y" where you do not class it as specific? I don't like conversations about definitions. I was using these words to describe a hypothetical inner experience; I don't claim that they aren't fuzzy. You seem to be pointing at the fuzziness and saying that they're meaningless; I don't see why you'd want to do that.
My point is that 1 and 2 above don't seem to differ fundamentally in either of the two descriptors you used.
Conversations about definitions of words are not useful, but definitions of concepts are necessary. I'm pointing at the fuzziness because it indicates to me that the supposed distinction is not being made based on any principle, but simply to rationalize a preexisting bias.
A few years ago, I wrote a little dialogue I imagined between 2 materialists, one of whom was for and one against abortion, centering on the personal identity question. I recently cleaned it up and added a number of references for the biological claims.
You can read it at An Abortion Dialogue.
Early feedback from #lesswrong is that it's a 'nicely enjoyable read' and 'quite good'. I hope everyone likes it, even if it doesn't exactly break new philosophical ground.
