This second type of knowledge is gained from an appearance. It requires attention (“their eyes were opened”) and can be instant, like an ‘ah-ha’ moment of sudden realisation or awareness.
So it seems clear to me that it’s this second form of knowledge that is gained by Adam and Eve: awareness of fear, gained from an appearance of nakedness. Their knowledge that ‘nakedness is bad’ is limited to singular situation. This is not knowledge of a ‘moral system’ as such. From awareness-type knowledge we begin to construct a moral system of value-attributed concepts, — Possibility
I agree with this interpretation of awareness. I think there are two metaphors in Genesis that relate to that awareness.
The common theme to both the allegorical tree of knowledge and shameful nakedness is self-awareness and self-consciousness respectively.
The tree of knowledge itself and lack thereof, provided a simple word picture for a metaphorical sense of finitude that we have only through our self-awareness. Meaning, as compared to lower life-forms who presumably don't have higher levels of consciousness and self-awareness, we have become aware of the concept of imperfection. And that speaks to the same sense of ignorance in all forms of temporal existence as presented to us in feeling our existential angst relative to the human condition.
To broad-brush it, whether it's a lack of perfection associated with our interpersonal struggles to seek satisfactory happiness, or deficiencies in our vocational needs or professional lives/science and a lack of knowledge and understanding about same, the natural world that we find ourselves in is in fact incomplete (Godel and Heisenberg).
Then there is self-consciousness coming from that same source of self-awareness. In this instance, I am self-conscious of my body. And I feel vulnerable to shame because I cannot choose otherwise. Moreover, I am now selfish through my self-awareness. I now have insatiable needs and I live a constant life of striving (Maslow). A feeling of existential angst has power over me (Ecclesiastes).
You are not what you could be, and you are not what you ought to be. And of course, what you are not you cannot perceive to understand; it cannot communicate itself to you. The chasm between what you are and what you ought to be is as unreconcilable as unresolved paradox from the so-called self-referential statements of Being (Liars paradox).
Covering yourself with clothing is a right response to this—to conceal it, and some argue, to confess it. In any case, we're aware of it, self aware. Henceforth, you shall wear clothing, not to conceal that you are not what you should be, but to confess that you are not what you should be. We have now become humble.
Fast-forwarding a bit, we do have opportunities to shed this facade (nudist colonies), in order to provide for a false sense of innocence. Hence my own personal experience (the foregoing thought-- experiment) of feeling joyful in that nakedness, and a feeling of no shame and no vulnerability. A liberation of sorts (both a discovery and uncovery of a truth/ Being), but a temporalness nonetheless...
