. So the presence of evidence for evolution makes no comment about the validity of Last Thursdayism, since it can be explained whether we accept LT or not.
Wrong. For evolution says the universe predated Last Thursday. If we accept LT, then we have to reject evolution. And if we accept evolution we have to reject LT.
The way Id look at this is LT is a an 'a priori' position, similar lets say to the kalam argument in theology. Its logically sound if we accept the axioms. Eg in the case of kalam, material infinites cannot exist, and a finite thing cant cause itself. In the case of LT, illusory age is real and that is that.
Wear kalam glasses, and you're a theist. Or you have theo-vision TM.
Take them off, and you've no commitment.
LT makes necessary claims (ie of unfalsifiability and illusory age
come what may) where as evolution is a contingent position. Different fossils discovered, theory updated etc. There is openness to new evidence and feedback.
Wear LT glasses, and its "true"...
To understand properly...
Two different pairs of glasses are required. One (LT) makes
indefeasible empirical claims, at the expense of scientific realism.
The other (evo) also makes claims about metaphysics (what exist and its nature), but in more of an
open system, and leaves the flexibility science intact.
BTW
open systems are known for their capacity to complexify, or to reduce entropy.
But a warning , systems with ongoing positive feedback loops (science has positive and negative) are often unstable. Think, advances in science can bring climate change and nuclear war etc.
On the other hand LT and the omphalos hypothesis is more of a closed system. The Bible says, it that settles it etc.
Maybe its a God send after all?
