Evidentialism and Why Ghosts Can’t Testify
I think there is a basic
misunderstanding as to the philosophical intent of materialism. It is usually
understood to mean that reality is made of stuff called “matter”, which is made
of quantum particle fields, governed by general relativity and quantum
mechanics. The equations are difficult and counterintuitive; quarks, leptons
and bosons solve them in real time; yet they are regarded as somehow stupid. “Dumb”
matter, “mindless” matter, though we are made of matter, and we say that we
have minds.
In addition to anthropocentric arrogance,
I also see a grammatical error at work here. I think a proper understanding of
materialism treats the word “matter” as a verb, not a noun. “To” matter, not “the”
matter; materialism is about what matters;
that is, what makes a significant difference.
This shift, from objects (“the”
matter) to thoughts (“to” matter), turns a question about existence into a
question about universality. This is a sound move, philosophically, because
existence is relative, transient and local, whereas universality is absolute,
eternal and global.
What does matter? Anything significant;
whatever has firm evidence in its favor. Hence materialism ought to be renamed ‘evidentialism’,
which accepts as real only that for which there is evidence. Materialism =
evidentialism = the call for proof of one’s statements.
The only reason why we talk about
quarks, leptons, bosons, etc., is that particle accelerators give evidence of
their existence. Matter as understood by 21st-century physics is radically
different from matter as understood by the 19th century; but the philosophical
demand for evidence remains the same.
Evidentialism is simply the demand to
not bullshit. It’s the philosopher’s usual unreasonable challenge: “prove it!”
Ask any religion about any other
religion. It will say that the other religion’s gods are immaterial in that they
are false and absurd, and hence do not really matter.
So riddle me this: why can’t ghosts
testify in court? Answer; because they are not material witnesses. By which the
lawyers don’t mean that the spook is made of ectoplasm rather than quantum
particle fields; they mean that the spook’s wailings and gibberings make no
sense and therefore are of no use to judge or jury. The ghost’s testimony is
immaterial because it doesn’t matter.
