A consequentialist might argue that it is, but then, consequentialists are wrong.

[EthanHeilman]

Given human nature, widespread belief in consequentialism as an ethical system would likely result is very bad consequences. So from the position that consequentialism is correct it is probably unethical to advocate as a correct viewpoint.

What if (purely hypothically) all consequentialists could agree on the same set of standards for what constitutes positive and negative utility?

[EthanHeilman]

How do you think this purely hypothetical conspiracy of consequentialists would go about convincing people to follow that set of standards?
