Those cave paintings are wonderful, but like everything we know, they
are not too wonderful to be true. It is their reality that gives them
wonder, and while there will never come a time when some of us will
not wish for more than we can have, the happiest of us will wait
confidently for other tangible finds. We treasure the cave at Altamira
where a century ago a little girl first saw the great painted bison.
New caves will be found, year after year, in lab or clinic or sky or
ocean depth, or even in ancient markings. That is the promise of real
science, which cannot allow wish to rule mind, but nonetheless finds
unendingly wonderful things.
