> It's like people who object to love being a chemical reaction. What else could it be possibly be?
Did you learn that by study, or did someone tell you that? Where else have you looked for love?
You might find “love” contained in the electrical impulses in a computer program. It might be in the words of a screenplay. A complicated mechanical automaton might experience love. You could notice it in a melody, or in the pattern of behavioral incentives among a society of human beings.
None of these things are chemical reactions in any systematic sense. You may notice chemical reactions everywhere you find these things, but that’s just because chemical reactions are contingently intrinsic to your own cognition. You’re only noticing yourself noticing the subject, and what you learn from that is almost entirely arbitrary.
Heartbreak is a form of neurotransmitter withdrawal, and it can be treated in similar ways to substance abuse issues. That’s because “love” is a “chemical reaction”. But that’s just a random fact about earthlings. It won’t help you write a pop song, let alone make a friend.
This is the reason “reductionism” has become a bit of a dirty word in philosophy. You feel like you are understanding the world better and better the whole time you are decomposing it into its constituent parts. Then you get to the bottom and you realize that the universe is made of many kinds of constituent parts, and you have decomposed a useful idea all the way down into nonsense.
