The fragility of time and the unconscious show me the past and will show you a present event affirming something called past. the future and the present suffer the same fate. — Constance
Which is why it is helpful to think of time in terms of William James "specious present", that duration, perhaps 2 seconds or so, in which we combine the immediate future, the instant present and the already passing moment in time. Anything less than that is something which we aren't aware of consciously, at these levels we react unconsciously.
If you deny the future and past, you cannot make sense of the present, because it has already past.
The unconscious: it takes but a moment to see that ANY talk at all about the unconscious is self contradictory, for to speak of it is to bring it to consciousness, thus, the moment it comes to our lips, rises up to thought and language, it is conscious — Constance
Not really. We see, roughly, when photons hit the eye and react to the photo-receptors we have. We aren't conscious of this process. We become conscious of it when we study mammalian vision, but, aside from the discussions, we don't see photons, nor do we see how the brain turns this into images.
And there is plenty of study in linguistics than show that we cannot introspect into our language faculty. What we get in consciousness are fragments, not the process by which we get these fragments.
Until we get rid of this idea of "access to consciousness", we will remain stuck in philosophy of mind, because, as a factual matter, the vast majority of the things we do don't enter experience. But this should be rather obvious, requiring little times reflection.
