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...
