Conscious experiences typically have a reflexive, self-aware character—when conscious of seeing red, you are aware of yourself as seeing, not just of red objects. This self-directed aspect raises questions: is self-awareness essential to consciousness? Does it require higher-order representation of lower-order states, or is it intrinsic to phenomenal experience?
Your prerequisite work on phenomenal vs. access consciousness established a useful distinction: phenomenal consciousness is what it is like to have an experience, while access consciousness is having information available for use in reasoning, report, and control. Reflexivity sits at the intersection of these two modes. When you consciously see red, something unusual happens: you are not merely registering redness, you are somehow aware that *you* are registering it. The experience is self-illuminating. This quality — that consciousness seems to point back at itself — is what philosophers call reflexivity.
The simplest account of reflexivity is the higher-order theory. On this view, a mental state becomes conscious when there is a higher-order state that represents it. Your first-order visual state registers red. A second-order state (a thought or representation about that visual state) then makes the first-order state conscious by taking it as its object. Consciousness, on this picture, is like a searchlight that shines on inner states — states it doesn't illuminate remain unconscious. This is an externalist model of self-awareness: the "self" awareness is produced by a separate, additional representation layered on top of the first-order experience.
A rival account, the same-order or self-representational view, argues that this regress is unnecessary and counterintuitive. On this account, phenomenal experience is inherently self-presenting — it doesn't need a second-order state to become conscious because the experience already carries within it an implicit awareness of itself as an experience. When you see red, the seeing is not a dark unconscious process that a separate higher thought makes visible; the seeing already announces itself as a seeing. Proponents like Uriah Kriegel argue this self-representation is a structural feature built into the phenomenal state, not a separate mentalistic addition.
The philosophical stakes become clearest when you consider the first-person/third-person asymmetry you likely noticed in studying phenomenal consciousness. Conscious experiences resist full third-person description precisely because they involve this reflexive, first-personal character. A complete physical description of your brain states doesn't automatically capture that these states are *for* you — that they present themselves to you. Reflexivity is part of what makes consciousness resist reductive explanation: a purely functional description of information processing seems to leave out the "witnessed by" quality that makes experience experiential. Some philosophers argue reflexivity is the deepest clue to what phenomenal consciousness is; others argue it is a systematic illusion produced by the way access consciousness introspects phenomenal states.
Bringing this together with your study of access consciousness: notice that access to a mental state is not sufficient for reflexive self-awareness. A thermostat "accesses" temperature information, but there is no self-illumination. The interesting philosophical question is whether phenomenal consciousness — having experiences with a subjective, felt character — is partly *constituted* by this reflexive self-presentation, or whether reflexivity is a separate, secondary feature. Your upcoming work on introspection and transparency will push this question further: if you try to introspect your experience of red, you seem to look right through the experience to the red apple, not at the experience itself. That transparency of experience is in tension with the claim that consciousness is essentially reflexive — a tension worth holding carefully as you continue.
