But there is no true/false in saying that torture is bad, unless there is another
hidden assumption such as "causing gratuitous suffering is bad", in which case
the question becomes, why is causing gratuitous suffering bad? Ultimately you
get to "it just is, so there!" It is the same in aesthetics: ultimately, you have to
assert that you think this looks better than that because that's just what you

What would you say to the Romans who attended events at the Colliseum,
and thought there was nothing wrong at all with feeding people to wild animals?
What would you say to an alien species which had reached a high level of
technological development by routinely killing the less intelligent portion of the
population in order to control their numbers and improve the gene pool? What
would you say to a citizen of Nazi Germany 70 years down the track if Hitler had
succeeded in conquering Europe and every schoolchild had grown up learning
what a great man he was? You could try to persuade them that your values were
better and nobler, but you couldn't persuade them that your values are more
rational or more consistent with the facts, because they aren't.

There are several differences between the axioms of ethics and aesthetics on
the one hand and those of logic, mathematics and science on the other. One is
that you can bet that any sentient species would arrive at exactly the same rules
of arithmetic and chemistry, but might have completely bizarre, or at least very
different, notions of ethics and aesthetics. Another is that matters of ethics and
aesthetics are not really third person communicable: an alien species may have
notions about these that can only be understood by someone with their psychology.
This is because ethics and aesthetics at a fundamental level involve emotion, whereas
science and logic do not. An unconscious machine might systematically churn out
mathematical theorems, but it won't ever provide an honest opinion as to whether
eating beans is good or bad. Finally, although in scientific discourse people might
eventually concede that they are dealing with axioms, in ethics especially this is
often taken as offensive, and part of the purpose of religion is to give an absolute
status to which at some level everyone knows is not absolute.

I am touched by your confidence that the rational will lead to the good,
and I wish it were so, but it isn't and it never has been. I would only be
a little less frightened of a rational murderous regime than of an irrational
