Tim Mulgan presents a penetrating examination of consequentialism: the theory that human behavior must be judged in terms of the goodness or badness of its consequences. The problem with consequentialism is that it seems unreasonably demanding, leaving us no room for our own aims and interests. In response, Mulgan offers his own, more practical version of consequentialism--one that will surely appeal to philosophers and laypersons alike.

This is a general introduction to consequentialism.

Derek Parfit, Philip Pettit and Michael Smith defend a version of consequentialism that covers everything. I argue that this version of consequentialism is false. Consequentialism, I argue, can only cover things that belong to a combination of things that agents can bring about.

I argue that we should reject all traditional forms of act-consequentialism if moral rationalism is true. (Moral rationalism, as I define it, holds that if S is morally required to perform x, then S has decisive reason, all things considered, to perform x.) I argue that moral rationalism in conjunction with a certain conception of practical reasons (viz., the teleological conception of reasons) compels us to accept act-consequentialism. I give a presumptive argument in favor of moral rationalism. And I argue that act-consequentialism is best construed as a theory that ranks outcomes, not according to their impersonal value, but according to how much reason each agent has to desire that they obtain.

The central problem for normative ethics is the conflict between a consequentialist view--that morality requires promoting the good of all--and a belief that the rights of the individual place significant constraints on what may be done to help others. Standard interpretations see Kant as rejecting all forms of consequentialism, and defending a theory which is fundamentally duty-based and agent-centered. Certain actions, like sacrificing the innocent, are categorically forbidden. In this original and controversial work, Cummiskey argues that there is no defensible basis for this view, that Kant's own arguments actually entail a consequentialist conclusion. But this new form of consequentialism which follows from Kant's theories has a distinctly Kantian tone. The capacity of rational action is prior to the value of happiness; thus providing justification for the view that rational nature is more important than mere pleasures and pains.

Lenman's ‘argument from cluelessness’ against consequentialism is that a significant percentage of the consequences of our actions are wholly unknowable, so that when it comes to assessing the moral quality of our actions, we are without a clue. I distinguish the argument from cluelessness from traditional epistemic objections to consequentialism. The argument from cluelessness should be no more problematic for consequentialism than the argument from epistemological scepticism should be for metaphysical realism. This puts those who would reject consequentialism on the ground of cluelessness in an awkward philosophical position.

Parfit argues that a form of rule consequentialism can be derived from the most plausible formulation of the fundamental principle of Kantian ethics. And so he concludes that Kantians should be consequentialists. I argue that we have good reason to reject two of the auxiliary premises that figure in Parfit’s derivation of rule consequentialism from Kantianism..

Contemporary theories of Virtue Ethics are often presented as being in opposition to Kantian Ethics and Consequentialism. It is argued that Virtue Ethics takes as fundamental the question, “What sort of character would a virtuous person have?” and that Kantian Ethics and Consequentialism take as fundamental the question, “What makes an action right?” I argue that this opposition is misconceived. The opposition is rather between Virtue Ethics and Kantian Ethics on the one hand and Consequentialism on the other. The former two are concerned with, respectively, the development of a virtuous character and a good will, whereas Consequentialism is essentially a doctrine that just provides a justification of the right option without specifying how this is to be achieved. Furthermore, I show that Consequentialism, interpreted as a justificatory doctrine, is both an impoverished doctrine and one that cannot be enriched by taking a “pick and mix” approach to other ethical theories in the way that Consequentialists advocate. I argue that there is at least one reason to prefer Kantian Ethics: Kantian Ethics necessarily avoids the objection of selfcenteredness, whereas the avoidance of this objection is only contingent in the case of Virtue Ethics.

In On What Matters Derek Parfit argues that we need to make a significant reassessment of the relationship between some central positions in moral philosophy, because, contrary to received opinion, Kantians, contractualists and consequentialists are all 'climbing the same mountain on different sides'. In Parfit's view Kant's own attempt to outline an account of moral obligation fails, but when it is modified in ways entirely congenial to his thinking, a defensible Kantian contractualism can be produced, which survives the objections which are fatal for Kant's own theory. This form of contractualism would then lead rational agents to choose consequentialist moral principles. I argue that Parfit significantly misrepresents Kant's project in moral philosophy, and that no genuinely Kantian moral theory could issue in a form of consequentialism.
