Massimo,

I guess I've made the point before, but the act of determination can only occur as the present.

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.

It's just that as these mobile organisms, with a sequential process of perception, arising from the need to navigate, our experience of time is as the present moving past to future, rather than change turning future to past.

Free will is also an oxymoron, as without cause, there is no effect and the premise of will is to affect.

We are part of nature's process of selection.
