But James divisablity is a sort of mental entertainment. The reality is that to apply reductionism to or in it's absolute form you will achieve your position. But this is merely reductionism from the whole and a labarynth is what you get.Quantum Heraclitus:
Any whole depends on its parts. A truly seamless continuum would depend upon indivisibility. The only thing which is indivisible would be a monad (an infintesimal quanta) by virtue of it being "the smallest one can be from nothing".
If there was evidence of time segmentation in reality I would not hesitate to agree but the distinction between what we think should be and what actually is needs to be drawn somewhere.
The whole is not divisable in reality but merely a way our minds like to disect and analyse. Put it in a box and it makes sense leave it as whole and stare in wonderment. Reductionism needs to be kept in perspective other wise we are trapped in our own mind games.
