You are still just getting your feet wet in phenomenology, but I celebrate your progress
I'm not saying you should rewrite part of your conclusions, but a reviewer might question one or two related statements there (related to what you write in 9.1/2). You could preempt those questions by foregrounding the point you make next here:
I think the growth of the mind (the potentiality for conceptual thinking) is dependent on many 'revelations' obtainable at the level of
reflective phenomenological experience, revelations of various kinds about the connections between ourselves and other animals, about the feelings inspired in us by nature and natural beings, and about the profound interconnections evidently woven throughout nature as it appears to us in local macroreality. Reflective phenomenological experience also opens us to/turns us toward awareness of the levels of our own consciousness so that our consciousness and thinking become a subject of equal importance to us. Phenomenal consciousness -- in discerning the birth of reflection and thinking out of our prereflective awareness of being in a world among other beings and things -- becomes a major part of our understanding of reality and therefore that upon which the mind works conceptually. I don't think your second and third 'constructs' can be radically separated. As you say above, "the levels feed into each other in marvellous ways," and these are already becoming the subject of the most interesting philosophy and science available to us now.
I think you are on the cusp of articulating the situation well. But what needs further exploration is the explanatory gap that exists between mind and world and how it comes into being. Can 'mechanisms' radically closed and separate from one another be understood to produce our reflexivity, our insights, and our freedom? How do we come to thinking, about ourselves
in and
of the natural world, and yet recognize our unique position as standing apart from -- and conceptualizing -- that which contains us, enabling in us in Nagel's words 'the view from nowhere'. Both the expansion of our conceptualization of the world and the freedom of our minds emerge in nature and are -- in some way yet undefined -- integral with nature. As Wallace Stevens expressed the idea,
". . . A new scholar replacing an older one reflects
A moment on this fantasia. He seeks
For a human that can be accounted for.
The spirit comes from the body of the world,
Or so Mr. Homburg thought: the body of a world
Whose blunt laws make an affectation of mind,
The mannerism of nature caught in a glass
And there become a spirit's mannerism,
A glass aswarm with things going as far as they can."
