The confirmation bias of those who insist that reality is purely subjective to the observer and that the repeatability, predictability and testability of science is meaningless, only reveals an intentional ignorance of that which does not fit into their personal reality.
The purely subjective reality is a completely impractical position to hold if only because one wouldn't be able to function without some belief that there are some kind of objective processes operating behind what we perceive.
Why believe that a ball would come down after you've thrown it up (On earth) unless you also accept the existance of such underlyin objective processes?
I agree. Similarly failing to see that there is a metaphysical assumption of objectivity in observations of objects as being separate from mind is also not correct.
How does that prove that evolutionary force (or whatever you call) is entirely separated from the evolving form?
In fact, a falling ball will always fall. Non-living beings will always disintegrate. But living beings become more and more organised.
The point was whether nature is entirely distinct from the evolving forms or whether the same nature is also the underlying nature beneath the particular natures of the living organisms? Whether we have motivation of self preservation or not? And whether we fully know the source of that motivation that drives every being?
