Nothing that does not exist can act or influene
Can this axiom ever be falsified? What means can be used to test that which does not exist for the ability (not tendency or recorded instance, but possibility) to act or influence? This axiom seems to imply that anything which cannot be observed as acting or influencing (that which is undetectable or, more accurately, which has not been detected) does not exist. Indeed, we exclude from our models that which we have no evidence off (observation of the thing or its effect or influence)- hence the rejection of deity, atoms (in the past), dualism, tachyons...
If this axiom is unfalsifiable, then no naturalistic/materialistic system is truly any different from any theistic system which rejects that particular axiom and accepts accepts as an axiom that 'Nothing within the physical universe can directly perceive anything outside of that universe' (hence God would be undetectable unless god is able to influence this universe and chooses to do so; lack-of-evidence ceases to be a valid reason for the exclusion of God from any model of the universe being construed)
I've gotten some interesting responses over at ATT, with people getting quite upset when the most fundamental aspects of their beliefs are challenged...
What say you of LoR?
