What It Is Like To Experience X The point of it is not to get drawn into what is ‘real’ or ‘existent’ - to ‘bracket out’ those questions as it doesn’t matter beyond experience in terms of subjectivity.
There are then ‘modes’/‘intentionality’. I can ‘view’ a box as an object, a tool, a vessel, a metaphor, etc.,. I can also think of a box (mode of ‘thinking about’).
We can then start to ask questions about items of experience. What ‘aspects’ or ‘parts’ of a box can be said to be the ‘essence’ of boxes? How many sides does a box need? Do we have to necessarily observe every side or edge of a box to appreciate it as a box (can we observe a box from every angle - the eidetic givenness of a box regardless of our limited perspective).
The primary mode of human understanding and philosophical thought stems from the phenomenological principle.
I think Husserl thought Kant used the term ‘transcendental’ to mean ‘thing in itself’ yet I’m not convinced Kant meant this dualistically - Husserl had a go at him about that (mistakenly I believe).
From the subjective day-to-day lived life we don’t act as if the world is phenomenal. Our world is materiality for the most part.
