This concerns philosophical discussions of the mind-body distinction and of the nature, concept and definition of consciousness & mind:
It maybe noteworthy that when more rationalistic philosophers, e.g. Karl Popper, are trying to define or explicate a notion of consciousness/mind for the purposes of a discussion/argumentation, they tend to emphasize sense-of-self as the defining or essential feature of consciousness/mind & de-emphasize actual qualia. (Which means they de-emphasize/ignore the concept that most directly and simply refers to subjective experience and the contents of consciousness in general – in favour of something more abstract.)
This maybe a consequence of the rationalistically stunted/inhibited introspection/vision of such thinkers: They fail to notice that one doesn’t actually see* a self – that self is a less concrete, more abstract entity, and that a sense of self is a very complicated basis for definition, as it is just an intuition/feeling of something that is already abstract and complex – unlike the more direct contents/constituents of consciousness, such as colours in a dream, which one does see. And the stunting of this kind of introspection or of introspective visual intuition occurs as follow:
Rationalists systematically ignore, neglect, devalue, inhibit, repress, and dismantle their intuition;**
then they destroy their understanding/idea of intuition;
then, in this new world where intuition is a broken and thus useless tool, they use just-based-on-an-intuition as an argumentative/rhetorical tool against opposing ideas, especially ones that clash with a rationalistic worldview.
*this can, theoretically, be generalized beyond the visual, but seeing suffices for the purposes of these points, and generalizing to something like perception in general to includes things like smells and tastes is counter-productively difficult because the notion of perceiving/perception is, in current philosophical discourse, too broken and confused.
**Taking intuition seriously/sincerely is antithetical to rational method/thinking, and intuitions are treated as something irrational and primitive that should be handled from the outside and treated with suspicion.
