indeed lots of old words and misconceptions about what they really mean...
...For one all there is in all time frames is real. Therefore necessary because by definition is all there ever will be and ever was. There is closure and fractals are the best evidence for it.
For a second all we can know about what is real is in experiencing which itself is more primitive than consciousness. Awareness is the Experience of experiencing, again phenomena.
For a third consciousness, itself does not imply free will nor agency, but rather a correlation of phenomena that mirrors awareness of patterns including awareness of epistemological inquiry and its narrative on potential alternative realities and its statistical probabilities limited by the computational power of the inquirer itself which is part of the totality.
The fact of the matter is that whenever we look back all history of phenomenology is one event, not many alternative events. Consciousness is therefore not what it seems. Not free, not causal, but just a correlation of a phenomenal narrative that we call the "physical" the material.
Bottom line, I don't agree either with classical rationalism nor with classical physicalism. Both concepts are obscure when we try to recur to their etymological classical cultural framing.
Consciousness is not free nor causal but rather a deterministic or perfectly correlated flow of necessary awareness of phenomena about phenomena which we then define as physical or real.
What we have is the Experience of experiencing rather than the experiencing of experience. The phenomena are the Noumena and complexity, all the complexity precedes the simplicity. This is why the idea of "emergence" is a mistake. I have a very intuitive feeling that the whole future commands the past and not the other way around. Just like a projection. There is nothing emergent when we see things from this pov.
