"Existence bourne of the subjective" is babble. It means nothing more than "an idea", and the idea of a thing is not the thing. Would you care to buy my "bourne of the subjective" car? How much will you give me for it? I have a bourne of the subjective title and everything. I'll even throw in a set of bourne of the subjective radials -- brand new... I just thought of them this very moment.
Existence means phenomenal reality. It means being actual, in a way which is at least potentially distinguishable from non-reality.
If existence is phenomenal then something must have the potential to be sensed to be said to exist? In this case existence is mediated through the human consciousness. But what we sense is not what is actually
there - it's merely an interpretation. In the example of sight, photoreceptors collect light. they send signals to neurons -and these generate electrical impulse which are processed by the brain. But the time it takes for light to travel from an object which we view to our photoreceptors means that we don't see what is there - but what was there at some moment in the past. So a phenomenal reality must necessitate existence as a construct of the human mind.
Or on a broader sense, we could ask why we should adopt such a anthropocentric view of existence? If the universe exists independently of human consciousness, why should it only be conceived through such a narrow viewpoint? How do we resolve a phenomenal reality with that which is altered by the measurement of being sensed?
Just to clarify, although this thread is in the religion forum because it presents a proof of atheism, it is not a thread regarding philosophy or metaphysics.
If you want to talk philosophy and metaphysics, please take it elsewhere, start a new thread.
I have no use for either of these, and they are irrelevant to the OP.
How can you hope to talk about god without recourse to metaphysics? How can philosophy be irrelevant to a proof of strong atheism?
