So, if feelings are just hormones chasing each other. Then why pay attention to any of them?
I don't think the organic cause of feelings trivializes them. (Perhaps I did not convey that thought as well as I thought I did in my initial comment.) The point was that they originate from within.
And some definitely shouldn't be listened to. Suicidal thoughts, for example, can be very powerful and strike without much warning. If you ever have them, I hope you don't listen.
