Consequentialism, as its name suggests, is the view that normative properties depend only on consequences. This general approach can be applied at different levels to different normative properties of different kinds of things, but the most prominent example is consequentialism about the moral rightness of acts, which holds that whether an act is morally right depends only on the consequences of that act or of something related to that act, such as the motive behind the act or a general rule requiring acts of the same kind.One common illustration is called Transplant. Imagine that each of five patients in a hospital will die without an organ transplant. The patient in Room 1 needs a heart, the patient in Room 2 needs a liver, the patient in Room 3 needs a kidney, and so on. The person in Room 6 is in the hospital for routine tests. Luckily (for them, not for him!), his tissue is compatible with the other five patients, and a specialist is available to transplant his organs into the other five. This operation would save their lives, while killing the "donor". There is no other way to save any of the other five patients (Foot 1966, Thomson 1976; compare related cases in Carritt 1947 and McCloskey 1965).
We need to add that the organ recipients will emerge healthy, the source of the organs will remain secret, the doctor won't be caught or punished for cutting up the "donor", and the doctor knows all of this to a high degree of probability (despite the fact that many others will help in the operation). Still, with the right details filled in, it looks as if cutting up the "donor" will maximize utility, since five lives have more utility than one life. If so, then classical utilitarianism implies that it would not be morally wrong for the doctor to perform the transplant and even that it would be morally wrong for the doctor not to perform the transplant. Most people find this result abominable. They take this example to show how bad it can be when utilitarians overlook individual rights, such as the unwilling donor's right to life.
This problem cannot be solved by building rights or fairness or desert into the theory of value. The five do not deserve to die, and they do deserve their lives, just as much as the one does. Each option violates someones right not to be killed and is unfair to someone. So consequentialists need more than just new values if they want to avoid endorsing this transplant.
Another popular charge is that classic utilitarianism demands too much, because it requires us to do acts that are or should be moral options (neither obligatory nor forbidden). (Scheffler 1982) For example, imagine that my old shoes are serviceable but dirty, so I want a new pair of shoes that costs $100. I could wear my old shoes and give the $100 to a charity that will use my money to save someone else's life. It would seem to maximize utility for me to give the $100 to the charity. If it is morally wrong to do anything other than what maximizes utility, then it is morally wrong for me to buy the shoes. But buying the shoes does not seem morally wrong. It might be morally better to give the money to charity, but such contributions seem supererogatory, that is, above and beyond the call of duty. Of course, there are many more cases like this. When I watch television, I always (or almost always) could do more good by helping others, but it does not seem morally wrong to watch television. When I choose to teach philosophy rather than working for CARE or the Peace Corps, my choice probably fails to maximize utility overall. If we were required to maximize utility, then we would have to make very different choices in many areas of our lives. The requirement to maximize utility, thus, strikes many people as too demanding because it interferes with the personal decisions that most of us feel should be left up to the individual.However, most people begin with the presumption that we morally ought to make the world better when we can. The question then is only whether any moral constraints or moral options need to be added to the basic consequentialist factor in moral reasoning. (Kagan 1989, 1998). If no objection reveals any need for anything beyond consequences, then consequences alone seem to determine what is morally right or wrong, just as consequentialists claim.
For me, it is about personal choice and considerations of others around us. We start with those we love, they come first. Then, we move down to acquaintances, they may or may not be deserving of our benevolence, but again, it is a personal choice. Beyond that, it becomes much more altruistic. To me, the summation comes from Spock in Star Trek: The Wrath of Khan; "The needs of the many outweigh the needs of the few, or the one". It is up to each and every one of us to make these distinctions for ourselves, within our belief systems.
