On Indexical' :
Change is just another placebo prescription for reality.
It is us that exist in an infinite and perpetual state of transition(belief states).
The arrow of reality is a timeless and motionless experience.
We simplistically just perceive the experience of reality in a multiplicity of ways.
Indexical' can point at a moment(belief state) within that multiplicity but they do not help describe them.
