A Refutation of Consequentialism? (I)
I'd like for someone to explain to me why the following isn't a sufficient refutation of consequentialism (at least of the maximalist or aggregative variety): One of the more over-reported anecdotes of the past century is Mao's retort to the question, "What was the significance of the French Revolution?" "It's too early to tell," Mao replied. Mao's point was partially tongue in cheek, but it managed to get across an important point: the effects of any action continue on into an indefinite, and at the limit, infinite, future. With that in mind, here's a refutation of consequentialism:
1) The right action in a given situation is a function of its net sum total consequences relative to alternative possible actions.
2) Sum net totals are calculated over total moments.
3) There are no total moments.
4) Hence, there are no sum totals.
5) Hence, there is no net sum total greater than all others.
6) Hence, there is no right action.
This is not an epistemic point. Of course it is hard to calculate out the consequences, and of course there is no reason whatsoever to believe that Robespierre could have made the considerations I just went over. But that is besides the point, which is that the consequentialist must be a realist about morality. The statement 'It is right in 1794 that Danton be executed' and its opposite, "It is wrong in 1794 that Danton be executed' must each have a determinate truth value. In general, any statement of the sort 'X is right' or 'X is good', if consequentialism is correct, must have a definite truth value, but no statement of that sort does. "It is right that Danton in 1794 be executed" is false in 1795, true in 1814, false again in 1816, true again maybe until 1914, false between 1914 and 1945, true again in 1946, and so on--which is just to say, "It is right that Danton is executed in 1794" has no definite truth value.
I suppose that one could argue that consequentialism is not a normative theory about what one ought to do, but is a descriptive theory that analyzes what we mean by statements of the sort 'X is right' and 'X is good'. But in that case, we have just shown that 'X is right' and 'X is good' have no definite truth values, and this, if any thing, speaks on behalf of error theory--and that, in turn, gets us to the same point: namely, that consequentialism is false.
