Luminance

The equivalent of pressure touch gradients to discern depth would be in visual terms, luminance gradients. I think luminance as the context in which details or objects emerge and then re-integrate is an interesting way of looking at how environments throw up different affects at different moments. That can never be divorced from the act of feeling which is always in its turn enmeshed with the act of perception. So, feeling-perception would have to be a double barreled term always.

I think this is along the lines of some of what Whitehead says.

This languaging of perception then seems to root it through duration. A duration where different intervals of luminance play out whilst remaining stable in an ecology of movement-environment interactions. Bodies are established out of these patterns across luminance thresholds. Otherwise every turn would create a different body that would not equate or stack together with the ones before- the multiplicity would unravel into single planes that could not maintain themselves in that they could not “do” anything or have an existence from one moment to the next.

This long-term staying power could be called envisaging.
