8 : affecting or assuming an air of superiority : SUPERCILIOUS
- su·pe·ri·or·ly adverb"Of the above definitions, I believe that only numbers 2 and 4b are pertinent, though number 8 certainly is a very apt description of your attitude. The first definition (2) leaves (I am sure you will agree) plenty of room for interpretation. For example, one might say that an employee at a grocery store has a supervisor who is her or his "superior". An investment banker might also have a "superior". Which of these two is "superior"? Many would say the banker's superior is superior to the grocery store worker's superior. Some would recognize that, for survival purposes, grocery store workers and their superiors are more important, and therefore superior to investment bankers.
The other definition (4b) gives its own example. Clearly the quality of superiority, in this case, depends on what you are discussing (cars, jobs, hair styles, religions, sexual orientation, species, knitting skills, typing skills, flying skills, web spinning skills etc.)
You said earlier: "Of course man is superior to animals - by any reasonable definition of the word." Since, based on dictionary definitions it is clear that some qualification is necessary, please qualify your statement, and BACK IT UP.
