This is not to deny that a consequentialist might have grounds to oppose abortion. 'Slippery slope' arguments can be framed by consequentialists (though I wouldn't in this case). Maybe embryos don't suffer, but a culture that tolerates the taking of human life risks going too far: where will it all end? In infanticide? The moment of birth provides a natural Rubicon for defining rules, and one could argue that it is hard to find another one earlier in embryonic development. Slippery slope arguments could therefore lead us to give the moment of birth more significance than utilitarianism, narrowly interpreted, would prefer.
