Proposed litmus test: infanticide.

General cultural norms label this practice as horrific, and most people's gut reactions concur. But a good chunk of rationality is separating emotions from logic. Once you've used atheism to eliminate a soul, and humans are "just" meat machines, and abortion is an ok if perhaps regrettable practice ... well, scientifically, there just isn't all that much difference between a fetus a couple months before birth, and an infant a couple of months after.

This doesn't argue that infants have zero value, but instead that they should be treated more like property or perhaps like pets (rather than like adult citizens). Don't unnecessarily cause them to suffer, but on the other hand you can choose to euthanize your own, if you wish, with no criminal consequences.

Get one of your friends who claims to be a rationalist. See if they can argue passionately in favor of infanticide.

Kudos to you for forthrightness. But em... no. Ok, first, it seems to me you've swept the ethics of infanticide under the rug of abortion, and left it there mostly unaddressed. Is an abortion an "ok if regrettable practice?" You've just assumed the answer is always yes, under any circumstances.

I personally say "definitely yes" before brain development (~12 weeks I think), "you need to talk to your doctor" between 12 and 24 weeks, and "not unless it's going to kill you" after 24 weeks (fully functioning brain). Anybody who knows more about development is welcome to contradict me, but those were the numbers I came up with a few years ago when I researched this.

If a baby/fetus has a mind, in my books it should be accorded rights - more and more so as it develops. I fail to see, moreover, where the dividing line ought to be in your view. Not to slippery-slope you but - why stop at infants?

*(Also note that this is a first-principles ethical argument which may have to be modified based on social expedience if it turns into policy. I don't want to encourage botched amateur abortions and cause extra harm. But those considerations are separate from the question of whether infants have worth in a moral sense.)

Once you've used atheism to eliminate a soul, and humans are "just" meat machines...

This gave me a nasty turn, because probably the most annoying idea religious people have is that if we're "just" chemicals, then nothing matters. One has to take pains to say that chemicals are just what we're made of. We have to be made out of something! :) And what we're made of has precisely zero moral significance (would we have more worth if we were made out of "spirit"?).

I mean, I could sit here all day and tell you about how you shouldn't read "Moby Dick," because it's just a bunch of meaningless pigment squiggles on compressed wood pulp. In a certain very trivial sense I am absolutely right - there is no "élan de Moby Dick" floating out in the aether somewhere independent of physical books. On the other hand I am totally missing the point.

Sorry, you have a point that my test won't apply to every rationalist.

The contrast I meant was: if you look at the world population, and ask how many people believe in atheism, materialism, and that abortion is not morally wrong, you'll find a significant minority. (Perhaps you yourself are not in that group.)

But if you then try to add "believes that infanticide is not morally wrong", your subpopulation will drop to basically zero.

But, rationally, the gap between the first three beliefs, and the last one, is relatively small. Purely on the basis of rationality, you ought to expect a smaller dropoff than we in fact see. Hence, most people in the first group are avoiding the repugnant conclusion for non-rational reasons. (Or believing in the first three, for non-rational reasons.)

If you personally don't agree with the first three premises, then perhaps this test isn't accurate for you.

So your point is that anyone who feels there is a moral difference between infanticide and abortion is irrational?

Because most pro-lifers already say that, in my experience.
