The Self, the Mind, Time, the Brain and Reality

The question is, what precisely makes something what it is; and what makes it the same thing with the passage of time?

Phenomenal consciousness is about the temporal “depth” of the present moment. The subjective “now” is, paradoxically, extended in time: it is “temporally thick.” We experience it not as an infinitely thin sliver of time but as a moment in which times present, past and future overlap. We travel through life as if in a “time ship,” which “has a prow and stern and room inside for us to move around.”

There is no clear dividing line in the brain between inner imaginings and perceptions of the real, solid “world out there.” Reality and fantasy are built into the same neural circuits.

It takes roughly seven billion billion billion atoms to build a 70kg human being. Adjust this figure according to your weight. The bulk of you (93 percent) is made up of oxygen, carbon and hydrogen, with nitrogen, calcium and phosphorus atoms accounting for most of the remaining 7 percent of your mass. Hydrogen has been around since the Big Bang, but the other elements are spewed out from the fusion factories of dying stars.

Neuropsychology is the study of the relation between brain and mind. We know what the brain is. It’s an organ located in the head. But what is the mind?

Writing about the self in the third person makes Mel uncomfortable.
