It might be more amenable to MCMC sampling than you think. MCMC basically is a series of operations of the form “make a small change and compare the result to the status quo”, which now that I phrase it that way sounds a lot like human ethical reasoning. (Maybe the real problem with philosophy is that we don’t consider enough hypothetical cases? I kid… mostly...)
In practice, the symmetry constraint isn’t as nasty as it looks. For example, you can do MH to sample a random node from a graph, knowing only local topology (you need some connectivity constraints to get a good walk length to get good diffusion properties). Basically, I posit that the hard part is coming up with a sane definition for “nearby possible world” (and that the symmetry constraint and other parts are pretty easy after that).
Maybe the real problem with philosophy is that we don’t consider enough hypothetical cases? I kid… mostly...
In that case we can have wonderful debates about which sub-space to sample our hypotheticals from, and once a bright-eyed and bushy-tailed acolyte breates out “ALL of it!” we can pontificate about the boundaries of all :-)
P.S. In about a century philosophy will discover the curse of dimensionality and there will be much rending of clothes and gnashing of teeth...
I basically agree. However...
