"dragons" and "unicorns" are concrete terms because they describe imaginable "things". it doesnt matter if they exist or not. thats my opinion, abstraction in this context is characterized through its un-imaginableness. we could debate about feelings like "love" "valor" "passion", and man could say feelings are a kind of preception. i would reduce perception to the 5 biological senses excluding feelings. to get a sharp grisp avoiding cases of doubts. opinions appreciated, c.s.
