Learning is not wholesale adoption of attitudes and values. Learning also involves application of knowledge to reality, which is entirely your own doing whether or not it was your own idea. So, with the question of "who's eye" - it's your eye, if you're using it. It's a matter of activity. Influence is inevitable but not something that cannot be transcended.
If allowed, I just wanted to comment on this. You can transcend influences
provided you are conscious of them (which implies thinking

). The subconscious influences, I guess, just become part of your personality. The problem with that is that it leads to pale imitation and cliché. Perhaps we would actually be flattered if someone said our photos were 'school of Ansel Adams' or 'school of Elliott Erwitt' or whatever. But influences can be much more subtle than that. Someone rather well known in the photography world once commented that my photos looked as though they were all taken in the 1970s, and it wasn't meant as a compliment. I don't actually care, because I just do what I like; but if you DO care, that kind of unconscious stylistic bias might be a problem. (Funnily enough, one photographer I'd be glad to be influenced by was active in the
1870s.)
@MTGseattle: I believe cohesion is to a large extent an emergent property. Pooling together advice I have gleaned in various places (and which I pass on without responsibility!), it seems to be widely recommended that you should take LOTS of photos of the stuff that interests you, and review them in a few months' time. Cull them mercilessly, and (if you have any left after that) it should be apparent what links them together and how to build further. But maybe you have already done that and passed that stage...?
