suffi ciently many people are added whose lives are worth living. |
C1. If A is a population of at least ten billion people with a very high |
quality of life, there must be some much larger imaginable population, |
Z, where the quantity of whatever makes life worth living would be |
greater even though its members have lives that are barely worth living |
(instantiation, P3). |
P4. If, other things being equal, the best outcome would be the one in which |
there is the greatest quantity of whatever makes life worth living, one |
outcome is better than another if the quantity of whatever makes life |
worth living is greater. |
C2. If, other things being equal, the best outcome would be the one in |
which there is the greatest quantity of whatever makes life worth |
living, Z would be better than A ( modus ponens , C1, P4). |
P5. Z is worse than A. |
C3. It is not the case that, other things being equal, the best outcome |
would be the one in which there is the greatest quantity of whatever |
makes life worth living ( modus tollens , C2, P5). |

Consequentialists think that we have a moral duty to bring about the best |
outcomes possible. The idea of the overall best outcome, however, typically |
involves summing good and bad effects distributed over different individuals. |
It is therefore frequently objected that consequentialism is indifferent |
to the separateness of persons, ignoring the distribution of good and bad |
consequences and implying that a great loss to one person could be justifi ed |
by smaller benefi ts to a great many others. |
Nonconsequentialists have often argued that we should not engage in |
this interpersonal aggregation β that it makes no sense to speak of what β s |
good or bad from β the point of the view of the universe β (Sidgwick, 382). |
Sometimes, however, rejecting consequentialism leads to positions that confl |
ict with common sense. In this much discussed article, Taurek rejects the |
idea that we have any obligation to save fi ve people rather than one other, |
whom he calls β David. β He argues that since there is no impersonal |
perspective from which we can judge either outcome better than the other, |
we are permitted to choose to bring about whichever outcome we prefer |

β though if we want to show equal concern to all involved, he suggests that |
we toss a coin so everyone has a 50 percent chance of survival. |
Not all aspects of Taurek β s argument are entirely clear. For example, |
interpreters differ as to whether he denies any notion of impersonal β betterness |
β (even so - called Pareto improvements; i.e., those that are better for |
someone and worse for no one) or only denies the intelligibility of impersonal |
claims where there is a confl ict of interests between two parties. |
Nonetheless, much ink has been spilled attempting to show that nonconsequentialists |
can resist his conclusion and justify saving a larger group of |
people without engaging in morally suspect aggregation. |
The claim that one ought to save the many instead of the few was made |
to rest on the claim that, other things being equal, it is a worse thing that |
these fi ve persons should die than that this one should. It is this evaluative |
judgement that I cannot accept. I do not wish to say in this situation that it |
is a worse thing were these fi ve persons to die and David to live than it is or |
would be were David to die and these fi ve to continue living. I do not wish |
to say this unless I am prepared to qualify it by explaining to whom or for |
whom or relative to what purpose it is or would be a worse thing. (Taurek, |
303 β 4) |
P1. If we call one state of affairs (impersonally) better than another, then |
one ought (morally) to prefer it. |
P2. It is not the case that David ought (morally) to prefer that he die so |
fi ve others can be saved than the reverse (they die so he can be saved). |
C1. It is not the case that David β s dying so fi ve others can be saved is |
(impersonally) better than the reverse (they die so he can be saved) |
( modus tollens , P1, P2). |
P3. If one state of affairs is not better than another, one is not required to |
bring it about. |
C2. David is not required to bring it about that he dies so fi ve others |
can be saved ( modus ponens , C1, P3). |
P4. If it is permissible for David to choose to save himself, it is also permissible |
for a third party to save David. |
C3. It is permissible for a third party to save David ( modus ponens , C2, |
P4). |
P5. If it is permissible to save one rather than fi ve, there cannot be any |
general obligation to save the greater number (in confl ict cases). |
C4. There is no general obligation to save the greater number (in confl ict |
cases) ( modus ponens , C3, P5). |
