Here's a way to think about it;

As these mobile organisms, this sentient interface between body and world functions as a sequence of perceptions, in order to navigate, so our experience of time is as the point of the present, moving past to future.

The reality is that activity and the resulting change turns future to past. Tomorrow becomes yesterday, because the earth turns.

There is no dimension of time, because the past is consumed by the present, to inform and drive it. Causality and conservation of energy. Cause becomes effect.

Energy is "conserved,' because it manifests this presence, creating time, as well as temperature, pressure, color and sound. Time is frequency, events are amplitude.

So energy goes past to future, because the patterns generated coalesce and dissolve, future to past. Energy drives the wave, while the fluctuations rise and fall.

Consciousness also goes past to future, while the perceptions, emotions and thoughts giving it form and structure go future to past.

Though it is the digestive, respiratory and circulatory systems processing the energy, feeding the flame, while the central nervous system sorts the information.

Consequently the tendency to concentrate on the information, rather than the processes generating it.

When you consider it though, the gut decides, the head advises.

Galaxies are also energy radiating out, as structure coalesces in, but that's another story.

Emerson also said, "We are but thickened light."
