- In defense of my undecidability thesis:
- I claimed that God's proof was mathematically undecidable for two reasons,
- 1. Mathematics can talk about Hyperbolic space, Orthodox Semigroups, Banach
- Algebras and Measurable Cardinals, but can't make statements about the real
- world.
- (I know this will be misinterpreted whatever I say, so out of laziness I won't
- elaborate)
- 2. It is easy to imagine epistemically indistinguishable worlds M and M' to our
- real world, one in which God exists, one in which he doesn't.
- (See my previous two postings.)
- One critique of 2 is that is depends on the viewer. For example, someone who
- claims to see a miracle or something contradictory to science may beleive
- he has grounds to infer the necessary existence of a God.
- (This, I gather, was the prime nature of one publicly posted response)
- Hence my response:
- The failure of what we believe to be a scientific law does not constitute
- evidence for God's existence. For, as any scientist must admit, science is
- incomplete. Would Newton, upon conducting the Michelson-Morley experiment have
- been able to conclude that necessarily, a God exists? No. Why? Because, in a
- fairly subtle way, Newton's science was wrong. Aberrations occured, and so
- science was modified.
- In the same way, there is absolutely no (epistemic) reason to believe that
- an unexplained phenomenon, (relative to the scientific knowledge of the time),
- is sufficient evidence for inferring the existence of a God. Surely the Newton
- example above shows this. In fact, regardless of what we ever do know, in
- particular, even if we never do explain certain phenomenon, this is
- no reason to infer that no causal explanation exists. Quite simply, this is
- confusing the issue of knowledge with existence, in that we are inferring
- that we do not know of any explanation that there is no explantion. Such
- questions of ontology must be kept quite distict from questions of
- epistemology.
- Regardless of scientific misunderstandings, it seems undisputable that the
- worlds M and M' do exists. Even if there was a chap who rose from the
- dead and performed miracles, and visibly rose to the sky, even if one bucket
- of fish fed thousands, even if two persons, Adam and eve suddenly materialized
- and all evolution is wrong, it is still possible to imagine the world which
- agrees with this but in which god doesnt't exist. Don't argue "surely this
- is a direct contradiction of physics" or "but what physical law could account
- for this?" . These questions have been resolved in the previous paragraphs.
- Don't overestimate the importance of so-called laws - a little reading
- in the philosophy of science will tell you this.
- Anyway, this strikes me as a pretty good defence of my position. I invite
- all comments, both e-mailed and public.
