(Although it seems to me to not to be about explaining human nature, but describing and re-framing it and offering life lessons from what I've seen so far. Or how does it explain the existence of consciousness?).
By my lights, it doesn't explain the existence of consciousness. I do not abide by all Heidegger concludes. I use Heidegger and the rest to keep my thoughts structured and competent, well guided. In the end there is still me and the world and this utterly profound mystery. Heidegger would say, mystery? Absolutely, this mystery, anxiety of being thrown into a world; something is wrong here. He is inspired by Kierkegaard and Nietzsche regarding some grandeur that is lost to us. N thought we are too much degraded by resentment while K thought we are alienated from God. Both thought that there needs to be a cure for this socially constructed alienation, which H defines as "das man", everydayness caught up in the unconscious involvement. Interesting: Buddhists and Hindus (sans the metaphysics) say the same thing. What ails us is this engagement day to day, from which we need to be liberated. What we REALLY are is something else, something better, extraordinary, transcendental (Buddhists differ, as perhaps you know. Mahayana Buddhism is filled with speculative content).
So - you make an ontological state of affairs assumption that there is a world which exists independently of your experience of it. Experience is therefore, amongst other things, a form of representation of that world.
If you want to talk like that, but it would be a retreat from what phenomenology is trying to do. Husserl, e.g., is NOT like Kant: there is a world of "unknown X" that we cannot experience. Same with Heidegger. Just take it as it presents itself; what it is. Here is a candle. The candle, says Husserl, has its basic analysis in terms of an eidetic predicatively formed affair. This IS like Kant saying concepts without inttuitions are empty; intuitions without concepts are blind. The object IS the conceptual/intuitive (sensorily) construction and this is just a descriptive account. There are assumptions of what the things is, but without the concpetual/predicative end of this, without the eidetic dimension, you are not describing what the thing is. What appears before IS idea and intuition, of-a-piece. You can separate them only in the abstract. Talk about sensory intuition as such is nonsense; you are, after all, IN eidetic contexts, or you are simply not thinking at all.
Now, if you have an interest as I do, you might side with Husserl over Heidegger: Husserl believed that in what he calls the phenomenological reduction, a suspension of imposing interpretative thought that is always already there when you open your eyes in the morning, this sort of thing takes a quasi mystical turn: it is the suspension of all ready assumptions, presuppositions that are already in place, what Heidegger later calls "proximal" thinking, as in, the basic furniture of our lived affairs of grocery shopping and quantum physics (to the extent these apply. Deep forested tribes untouched by modernity hardy go shopping in our sense of the term). It is, I think, what a meditating yogic does with great rigor. Husserl says that if you do this, often, it creates a distance between you and, ala Heidegger,
Being-in-the-world, and HERE, there is a possible religious ...errr, encountering the world of novel insight. See, if you have a mind, Anthony Steinbach's Phenomenology and Mysticism. Also see Phenomenology and Religion, New Frontiers, an anthology of post Heidegerian thought.
I have these texts pdf if you want them.
A world which you share with other people, and compare notes about. And hence we have the inter-subjective basis of a working model of the world we share. A world where there are inedependently existing things and processes. We can't know about these other things and people from a first-hand pov, but we can agree on limited and flawed descriptions based in our shared observations and reasoning. And we end up with a (flawed and incomplete) scientific, materialist working model of the world.
Agree so far?
Absolutely.
That model contains an evolutionary explanation of why we are the way we are, physically, and why we have certain types of experience. A limited, flawed explanation, which doesn't explain the source of experience (but then neither does phenomenology?). But does give a broad utility-based explanation for things like our caring, social pre-dispositions, our competetive and tribal instincts, why we like choclate and so on.
Absolutely.
So what is your problem with that approach to human nature? Where do you draw the line on explanations which arise in the world we share, and why? Presumably you accept what we call gravity tells us something real about the world, and you accept evolution tells us something real about why our bodies are the way they are - so why draw the line at what evolution tells us about why we are the way we are mentally?
Simple. Empirical scientific thinking is NOT foundational ontology. That "what is" of the world at the level of basic assumptions is not addressed at all. Even if you have an a sound empirical theory about the nature of conscious thought, a neurologist's or a psychologist's, you are still not examining the nature of thought itself. A first step in this direction sees with perfect clarity that such an examination presupposes thought IN the empirical examination. This clear insight is at the heart of a LOT of philosophy. Thought examining thought is, by nature, impossible (Wittgenstein) for you would need yet another systematic symbolic pov/standard to stand apart from the thought perspective that is doing the examining; and this would yet require another to examine it! An infinite regress.
Heidegger sees exactly this, and responds: hermeneutics! Circularity IS what IS at the level of basic assumptions. He is right about this. He has opened the door, however, to possibilities, interpretative possiblities, and this is why I value his philosophy: the world is OPEN at the very foundation of meaning making itself. Scientific paradigms are in abeyance, as are all, even that of phenomenology.
Now I can anticipate your objection: This is exactly what science IS, a theoretical openness, founding paradigms questioned, revolutions in the structure of science itself, and so on. Heidegger says YES! the method of phenomenology is not at all a repudiation of science. But it is not working with THOSE paradigms. It works apriori, what is presupposed by empirical paradigms. It is another order of thought entirely, embracing science, religion, sociology, anthropology, and all the rest under one single paradigm, that of hermeneutics.
In order to see the importance of this, one has to work through the literature.
