Thoughts on a Version of Consequentialist Ethics

Ethics is never far from the surface of discussions of economics, especially practical economic polices. Adam Smith, for example, was also an ethical theorist. We also have the spectacle of the Austrian Murray Rothbard who tried to defend and justify his anarcho-capitalist system mainly on natural-rights ethical grounds.

The limitations of early versions of hedonistic utilitarianism are well known, of course: the difficulty of reliably comparing interpersonal utility, and so on.

But hedonistic “act utilitarianism” is only one version of a myriad of ethical theories that can all be subsumed in the broader category of consequentialism.

And consequentialism as a broad group of theories can itself be categorised as one of the two species of teleological ethics, as follows:
Teleological (broad Consequentialist-type) Ethics:
(a) Virtue Ethics
(i) Eudaemonist theories
(ii) Plato’s eudaemonist ethics
(iii) Aristotle’s eudaemonist ethics
(iv) Stoic ethics (with natural law)
(v) non-eudaemonist virtue ethics
(vi) agent-based virtue ethics of Michael Slote
(vii) neo-Aristotelian ethical naturalism (P. Foot; R. Hursthouse)
(b) Consequentialist (minimal/moderate moral realism)
(i) Utilitarian-type theories
- Hedonism
- egoism (the 17th-century English philosopher Thomas Hobbes)
- universal/universalistic hedonism = utilitarianism (Bentham, Mill, and Sidgwick): act utilitarianism, rule utilitarianism

(ii) Consequentialist/Other teleological/utilitarian-type
- ideal-moral-code rule consequentialism (Hooker 2000; Richard Brandt)
- preference rule consequentialism (John Harsanyi)
- Motive consequentialism (Robert Adams)
- ideal consequentialism/utilitarianism (G.E. Moore; Hastings Rashdall)
- preference consequentialism/utilitarianism (R. M. Hare; Peter Singer)
- two-level preference consequentialism/utilitarianism (R. M. Hare)
- negative consequentialism (Popper, Christoph Fehige and Clark Wolf)
- evolutionary ethics, with ends of action, survival and growth (Herbert Spencer) power, as in despotism (Niccolò Machiavelli and Friedrich Nietzsche)
- satisfaction and adjustment, pragmatism (Ralph Barton Perry and John Dewey)
- freedom, existentialism (Jean-Paul Sartre)
- Buddhist ethics
- Mohism (Mo Tzu/Micius)
- Ayn Rand’s objectivism?
There is in fact a high degree of compatibility between a number of modern consequentialist theories.

While I don’t directly endorse any one particular theory above, I suspect that a workable version of consequentialism would require concern for a number of ends, and would draw on various of these theories.

As I think of ethics more and more, I am starting to see some merit in certain aspects of Virtue ethics and Rawl’s rights-based ethics.

Morality must be concerned not just with happiness, but clearly with fairness, justice and justifiable human rights as well.

But my position is in no sense an endorsement of any natural rights theory of ethics, a theory which, I think, remains nonsense. Rights are not natural; they are ethical constructs, requiring rational justification, and requiring human institutions and human beings to enforce them.

I suppose a serious ethical theory must pass three tests:
(1) it must not commit the “appeal to nature” fallacy;

(2) it must explain how it overcomes or is consistent with G. E. Moore’s “naturalistic fallacy,” and

(3) it must explain how it overcomes or is consistent with Hume’s “is–ought” problem (sometimes called Hume’s Law and Hume's Guillotine).
A complete answer to the question whether the “good” is really identifiable with natural properties (as naturalism contends), or is an indefinable, non-natural property (as G. E. Moore argued in Principia Ethica) I leave as an open question for further thought, although I do now lean towards the view that the “good” is at least explicable for humans in naturalistic terms.

According to Moore, all naturalist ethical theories commit the “naturalistic fallacy,” though there is some dispute on what exactly Moore meant by this. The “naturalistic fallacy” is not simply a crude fallacy called the “appeal to nature,” which is the assertion that what is natural is therefore inherently moral. Nor would some philosophers say that the “naturalistic fallacy” is the same as Hume’s “is–ought” problem.

Moore’s “naturalistic fallacy” consists in the (alleged) fallacy of identifying the property of goodness with some other natural property or thing.

For example, one could say:
(1) Pleasure is good.
This is a proposition, but it has two possible meanings, as follows:
(1) Pleasure is a thing that has the independent property of being good.
(2) Pleasure is identical with the concept “good.” That is, they are one and same thing.
In order to understand what Moore means, we must understand the somewhat confusing grammatical differences in the way the word “is” is used in English.

The verb “is” has 3 possible grammatical uses in English:
(1) to covey identity, e.g., “He is John” (They are one and same thing);
(2) predication (as the so-called copula or linking verb), e.g., “This desk is white” (that is, this desk has the property of being “white,” but obviously the “desk” per se is simply not the same thing as “white”);
(3) existence or being, e.g., “There is a high mountain two miles from here” (that is, there exists a mountain that is two miles from this location).
Just because we can use the word “good” with “is” in sense (2), Moore says, it does not follow that anything supposedly having the property goodness can be identified with the “good” in sense (1) (that is, identity). To assert that anything natural x is actually identical with the “good” in sense (1) is the “naturalistic fallacy.” Moore therefore contends that the “good” is an ineffable and non-natural property.

Whatever one thinks here, it is still possible in principle to be a moral consequentialist and to accept Moore’s non-naturalist views on the nature of the “good” (Levine 2002: 136), and then proceed to construct a consequentialist ethics. Moore himself did so, and was a moral consequentialist.

As to Hume’s “is–ought” problem, this seems rather more difficult. Now many philosophers contend that it is very easy to derive an “ought” from an “is” in a non-moral sense. For example, a working clock keeps time, so logically a clock ought to keep time in a sense that is non-ethical, that is, merely teleological. But that does not really help the moral theorist.

For example, one can observe the empirical (descriptive) fact that leaves naturally fall under the influence of gravity to the ground. Does it follow from this in a clear logical way that a leaf has a moral right to fall to the ground? No, it does not. My stopping the leaf falling to the ground does not appear to be immoral in a way logically derivable from the descriptive fact. Just because the nature of a leaf is to fall to the ground under the influence of gravity, it does not follow that the leaf has any moral right whatsoever to fall to the ground.

You can complain that morality should only involve sentient beings. But the difficulty is still apparent. If a person takes possession of unoccupied property never claimed by anyone else, this can also be expressed as a descriptive fact. But does it follow from the descriptive fact that such a person now has a moral right to absolute ownership and use of his homesteaded property? Is the moral statement “John ought to have the right of absolute ownership and use of his homesteaded property” a proposition that is true and justified (a moral fact) derivable from the previous mere descriptive fact? It does not logically follow.

If we say that “theft is the cause of serious problems in human society,” how is the moral injunction that follows, that “you ought not to steal,” a morally justified, true ethical fact? How do you derive that “ought” from the “is”?

If one wants to argue that all moral injunctions are really teleological imperatives to achieve some aim or end, then I suppose one has solved Hume’s “is–ought” problem, and endorsed some form of non-cognitivism, the view that there are in fact no “moral facts” as such and no “moral knowledge.” One version of non-cognitivism is the prescriptivism of R. M. Hare: what we think are ethical statements are just imperative statements. “You ought not to steal” becomes “do not steal!” but in a sense that is not a moral fact, but an imperative. Strictly speaking, the prescriptivist argues that any moral judgement is not a descriptive statement and is never entailed by any other descriptive fact.

That is, if one wants to admit that a moral “ought” statement does not really possess the property of truth or falsity, and in fact is never true or false, and can only be obeyed or disobeyed (since it only urges a course of action as an imperative does), then one has evaded Hume’s “is–ought” problem (though the prescriptivist, however, asserts that one can still reason about moral imperatives, not just about descriptive facts).

But many might complain that this a high price to pay for having solved (or perhaps evaded) Hume’s “is–ought” problem.

Other moral naturalists contend that one can derive the moral “ought” from “is,” and see the answer in the nature and logic of goal-directed behavior. I am not sure they have really solved the problem, and at best one should subject all claims to deriving a moral prescription from some descriptive fact to careful scrutiny.

Perhaps the solution really is to say that assumed moral injunctions are imperatives. Whatever justification is given consists in asserting that actions are urged to achieve certain ends to allow human society to function in a way that is conducive to order, known rules, predictability in life and social harmony. A direct moral injunction does not constitute a true moral statement at all, but is an imperative to urge action in a teleological sense to make society work.

That is the basic utilitarian function of what we call morality, and once one has proposed ends or aims, one can
(1) defend them by showing how other moral theories are flawed and unjustifiable;

(2) defend one’s proposed ends or aims in discourse to see how far one can obtain agreement from other human beings, and

(3) logically and empirically examine how to achieve the teleological ends: that is to say, what consequences follow about what should be done and should not be done to achieve the stated aims.
Returning to the main argument, crude versions of utilitarianism focusing merely on happiness/pleasure/utility as the sole good are inadequate, but not more sophisticated forms of consequentialism that argue that multiple moral aims (or consequences) are what must be aimed at.

I would propose a version of consequentialism that holds we should aim at more ends than just utility/happiness such as the following:
(1) preservation of human life where the people in question wish to continue to live and we can clearly ascertain this* (e.g., the man dying of disease in a highly privatised system of health care, the starving human being who is unemployed and who finds no private charity). Such an end has precedents in 20th century forms of consequentialism.

(2) minimising suffering, especially where this can be done with redistribution of resources that are relatively abundant (on this point, I wish to take Karl Popper’s negative consequentialism and make it part of a larger consequentialist system).

(3) aiming at the end of respecting certain individual rights where not doing so would harm the functioning of society significantly or would violate the sense of justice or fairness that an individual must feel to have respect for the law and confidence in others, in so far as this does not lead to gross violations of (1) or (2) (on this, I think notions of justice and fairness are legitimate ends, as in Rawls’s critiques of some crude utilitarian theories).

* Although this is quite compatible with the idea of voluntary euthanasia when expressed clearly by those of sound mind suffering from painful terminal disease, I will leave this question open.
These additions to consequentialist ends aimed at overcome most of the traditional objections to utilitarianism.

I suspect the alleged incompatibility of consequentialism with other theories is exaggerated.

This is an ethics that strongly supports the right to be free from unjustifiable coercion, unjustifiable suffering, arbitrary killing, and theft (non-justifiable appropriation of external property), but at the same time the limited right to control over external property.

But also one’s right not to die simply because one cannot find a job in a laissez faire society or successfully beg for private charity; and the right not to live in poverty or without adequate health care, and so on.

Addendum
Here is a puzzle for grammarians and philosophers.

What is the grammatical status of this sentence?:
“When playing a normal* game of chess, one ought to play to win the game.”

* Normal in the sense of not playing to deliberately lose or draw.
I suppose the obvious answer is that it is a sentence in the subjunctive mood.

Some might complain that the grammatical form of the sentence is misleading. Perhaps it is really just an imperative: “Play a normal game of chess to win!”

But can it be understood as a true proposition? That is, it is simply a true statement that a person playing a normal game of chess plays to win in a teleological sense. This is the purpose of chess.

Can a subjunctive even be true or false?

In addition, it is clearly not an ethical proposition. If you do not play a normal game of chess to win, then you are not immoral or evil, but simply acting contrary to the convention of behaviour required by the game.

Economics and Ethics: A Brief Survey

In the previous post (see “Rothbard on Mises’ Utilitarianism: Why the Systems of Mises and Rothbard both Collapse”), I pointed out that Rothbard’s natural law theory is untenable, and once that is recognised his whole case for anarcho-capitalism also collapses. While I will publish a longer post soon refuting natural law and natural rights theory, I present here a brief introduction to ethics. This post was also published as a guest post on the Cynicus Economicus blog ( “Guest Article: Economics and Ethics,” May 4, 2009).

For a number of economic systems (e.g., libertarianism, free market economics, neo-liberalism, social democracy, democratic socialism, communism etc), in intelligent debate many people justify their preferred system as public policy by appealing to some ethical theory, to convince other people of the morality or superiority of their system.

The Austrians who follow the praxeological system of von Mises claim that economic science is value-free, and that the inferences of praxeology are justifiable as economic laws independently of ethics, though that remains a questionable idea. But, as a public policy prescription, even Austrians will often require an ethical theory, and Rothbard explicitly used natural rights theory to justify his anarcho-capitalism.

In the end, when an economic system is urged as a policy it must often be justified or limited by an ethical/moral theory, and one needs an objective theory of right or wrong to do this. For the only effective theories available to justify a larger philosophical system in a consistent way are objectivist theories of ethics (that is to say, a subjectivist or relativist theory of ethics is self-defeating).

In essence, an objectivist theory of ethics holds that:
– moral judgements are propositions that have an objective value, either true or false (e.g, “The unjustified killing of another human being is wrong”);
– the truth of a moral proposition remains true regardless of the subjective opinions of a person or the values of a different culture (e.g., “Slavery is wrong”);
– morality is not subjective or relative.
If we want an objectivist theory of our morality, we essentially have these options:
(1) Moral absolutism
(a) Divine Command Theory
(b) Categorical Imperative ethics (Kantian ethics)
(2) Moral Universalism (minimal/moderate moral realism)
(i) Deontological theories:
(a) Natural law theories (Plato and many Christian philosophers)
(b) Thomist ethics
(c) Pluralistic deontology, the non-absolutist ethics of W.D. Ross
(d) Human rights objectivism (Rawls)
(ii) Consequentialist theories:
(e) Utilitarianism (act utilitarianism; rule utilitarianism)
(f) Ayn Rand’s objectivism?
(3) Ayn Rand’s objectivism?
(4) Utilitarian Kantian Principle of James Cornman (this combines deontology and utilitarianism).
All of these objectivist theories of morality/ethics can be divided into two basic groups as follows:
(1) Deontological theories (= duty or obligation based morality): the basis of morality is duty and some acts are always right no matter what consequences they can cause (the best example of which is Kantian ethics or some forms of divine command theory; Kant famously said that it is always wrong to lie, no matter what the circumstances).

(2) Consequentialist theories: the basis of morality is the evaluation of the consequences of acts on people (the most famous such theory is Utilitarianism). The greatest happiness of the greatest number of people is one way of describing it.

(I will not address the question whether Ayn Rand’s objectivism is consequentialist or in a category by itself, since this is disputed.)
Use your intuition and find out whether you subscribe to (1) a duty-based ethical theory or (2) a utilitarian or consequentialist ethical theory by thinking about this moral problem:
A known murderer comes to you and asks to know where a person he wants to kill is, and you are aware of his desire to commit murder. Do you:

(1) Lie to protect the innocent person and say you do not know, or
(2) Tell the murderer where that person is in the knowledge that a murder may occur?
Decision (1) makes you a utilitarian, and (2) a believer of duty-based ethics. Immanuel Kant held that (2) is the moral course of action, since lying is always immoral, under all circumstances.

Ethics as Applied to Economics

Divine command theory is easily refuted: e.g., if god orders someone to commit genocide, then this suddenly becomes a “moral” action, because God has ordered it. Thus divine ethics turns out to be a subjective theory of ethics: what is moral and what is not actually depends, in the end, on the arbitrary whim of God, not the goodness of actions or their consequences. If God’s moral laws are not arbitrary, then there must be some independent, objective standard or method he uses to determine what is right and wrong. But, if there is an independent, objective standard, then it is this system that tells us what is right or wrong, not the commands of God. We could presumably use reason to apply the standard ourselves to discover what is right and wrong, without any need for instruction from God. (And Kantian ethics was in fact partly an attempt to create an objectivist ethics that could defend Christian morality, but remove this problem by basing morality on moral principles derived from human reason.)

Many libertarians rely on a natural law/natural rights theory of ethics.

Thus they often argue that state intervention is bad when it violates private property rights, and that this government action is always immoral, irrespective of the good or bad consequences that state intervention has or may have.

Natural law as a theory can be traced back to Plato, the ancient Stoics, and many Christian philosophers. (Contrary to popular belief, the most widely-held theory of ethics in the Middle Ages in Christian philosophy was the natural law theory, not the crude divine command theory.)

Natural law was famously attacked by the English utilitarian philosopher Jeremy Bentham as “nonsense on stilts.”

One of the main weaknesses of natural law theory is that its main historical justification was the belief in a “divine order” and a divinely-created human nature that makes us conform to “natural law.”

For Plato, the divine soul made human beings conform to the natural law of the universe. In ancient Stoicism, all humans had a divine reason given by the gods to make them adhere to divine “natural law.”

When natural law theory was taken up by Christian theologians, they simply substituted the Christian god for the gods of the Greek and Romans.

In the early modern period, rationalist European philosophers like Grotius tried to defend natural law theory by removing God and the previous supernatural justification for it.

However, in doing so, they destroyed the only convincing explanation for belief in natural law (Tawney 1998: xxv-xxvi).

Thus anyone who accepts an atheistic and naturalistic scientific view of the universe, and who rejects all religion, has no reason to believe in natural law or natural rights.

I would note here that just because we appear to have an innate sense of right and wrong, this does not provide us with an objective system of ethics. That some scientists believe they can identify an innate sense of right and wrong, which humans have evolved through social life in communities during our evolutionary history, does not mean that they have found an objectivist theory of morality that can function as a consistent, logical and universal system for justifying our moral choices, both now and in the past. The well-known fact that there is a vast chasm between what can be regarded as moral in one society and immoral in another demonstrates that, like our language faculty (which also has a biological basis), our innate moral intuition can lead to quite different systems of morality in different cultures in different times (just as our core language faculty leads to vastly different languages, with different words, grammar and syntax). For instance, in ancient Greece and Rome, the killing of unwanted children by exposing them (i.e., leaving them at crossroads or abandoning them at birth) was widely accepted. Human sacrifice and slavery were also widely practised in many ancient societies, and this was apparently perfectly compatible with the “innate moral sense of right and wrong” that ancient people had, although it is no longer accepted today.

Only an objectivist theory of morality can demonstrate that these things are immoral now and also immoral in the past. So it turns out the innate sense of right and wrong is not the same thing as an objectivist theory of morality.

Nor does appealing to “nature” give us any objective standard of right and wrong. For example, cannibalism is observed in many species: does this make cannibalism moral for humans? It certainly does not, and anyone who thinks so has committed the fallacy of appeal to nature, a fallacy of relevance.

I will note here too that a very good starting point for why natural law and natural rights are untenable is Kai Nielsen, “The Myth of Natural Law,” in S. Hook (ed.), Law and Philosophy: A Symposium, University Press, New York. 1963.

Also relevant is L. A. Rollins, The Myth of Natural Rights (Loompanics Unlimited, 1983), which is an attack on the natural rights theories of Rothbard and Ayn Rand.

It follows that all modern types of libertarianism or free market economics based simply on a “natural law” or “natural rights” foundation are severely flawed systems (e.g., the systems of Adam Smith or Murray Rothbard). There is no reason to believe that the “natural law” that justifies placing inviolable property rights at the centre of our modern political or economic systems has any validity whatsoever.

In my opinion, Kantian ethics has no real consequences for economics: it can be used to justify numerous economic systems and is fully compatible with social democracy. However, Kantian deontological ethics has severe problems.

A better ethical theory, in my view, is a modern form of utilitarianism called rule utilitarianism (which is quite different from its crude early form as advocated by Jeremy Bentham). Some libertarians or advocates of free market economics actually do use utilitarian arguments to justify their positions and economic systems, e.g., Ludwig von Mises (although Mises’ praxeology was an a priori system of deductive reasoning, independent of his utilitarianism), the earlier Friedrich von Hayek (Gregg 2003: 21–22), and Milton Friedman (Frederick 2002: 23). Thus anyone who uses a utilitarian argument to support ideas about economics will ultimately have to examine the good and bad effects of the policies they advocate.

In these theories, there is no reason in principle why state intervention could not be moral and successful. Any economic argument, then, essentially becomes an argument about empirical reality: the consequences of economic policy today and in the past. The good consequences of state intervention and social democracy fully justify these policies. Of course, philosophical objections have been raised to utilitarianism as well.

One solution may be that we should adopt James Cornman’s Utilitarian Kantian Principle of ethics: this (as I understand it) has caused a great deal of excitement amongst modern philosophers, because it combines the best elements of Kant’s deontological ethics with utilitarianism. It is perfectly compatible with state intervention in economics.

APPENDIX 1: WHAT WAS MARX’S ETHICS?

Marx himself, as I understand it, rejected the utilitarianism of his day for some very confused ideas on ethics (Alan Gilbert, Democratic Individuality, Cambridge University Press, 1990, p. 240). And, at the very least, the question of what ethical theory he believed in is debatable (N. Churchich, Marxism and Morality: A Critical Examination of Marxist Ethics, James Clarke & Co., 1994, p. 139).

Since I don’t advocate communism as preached in the Communist Manifesto, it has nothing to do with my moral argument for certain types of state intervention.

Furthermore, the means Marx advocated to achieve communism (i.e., dictatorship, destruction of freedom of speech and civil liberties) can be rejected on utilitarian grounds anyway, since the abolition of freedom of speech and dictatorship have harmful effects on everyone.
