Another possible source of evidence for the mind's surviving the brain is the occurrence of neardeath

Even
the
famous
atheistic
philosopher
A.
J.
Ayer
reported
a
near-death
experience
that
temporarily
weakened
his
conviction
that
death
would
be
the
end
of

However,
reports
of
neardeath
experiences
are
only
very
weak
evidence
for
the
existence
of

because
science
provides
plausible
alternative
explanations.
Heart
