Although it's a bit of a side-track and you're quoting, what are your thoughts on applying this logic to "computer _science_" or "material science"?
I think it's more about the age of the field:
1. pretty old fields like physics (which just comes from the Greek word for nature), chemistry (comes from the art of making alloys) just have names describing what is studied without adding something that says "study of".
2. a lot of newer sciences (e.g. biology, geology, psychology, sociology) we use -logy as a suffix meaning "field of study", again from ancient Greek. Some of these are natural sciences, some others are social sciences.
3. in newer fields of study, rather than deriving new Latin/Greek names we just use "X science", which is not that different from what's being done in (2) A major exception to this is the medical fields (like oncology) where we still use -logy because Latin/Greek roots are still in common use in medicine.
Indeed, the mere proliferation of x-studies (where x is arbitrary) in universities is a ringing indictment. The classic/liberal humanities (e.g. history) should be taught but it shouldn't be the case that one must go to a university, and get into debt, to learn them, and within a university where they are taught, they shouldn't be degree courses unto themselves.
Music is taught excellently in conservatoires and art taught in ateliers imho produces better artists than are produced by universities. Both are often an order of magnitude cheaper than a 4-year university education and encourage/reward the repetition necessary to achieve excellence in those who aren't naturally gifted.
Any field that has to append "science" to its name usually isn't scientific e.g. political science, social science.[0]
