Ethics

What should we do? What is normative?

What may a man do and not be ashamed of it? He may not do nothing surely, for straightaway he is dubbed Dolittle—aye! christens himself first—and reasonably, for he was first to duck. But let him do something, is he the less a Dolittle? Is it actually something done, or not rather something undone?1

Nothing in the world—indeed nothing even beyond the world—can possibly be conceived which could be called good without qualification except a good will.3

Introduction

Thrasymachus in Plato’s Republic:

Listen then, I say justice is nothing other than the advantage of the stronger.10

Hume:

Morals and criticism are not so properly objects of the understanding as of taste and sentiment. Beauty, whether moral or natural, is felt, more properly than perceived. Or if we reason concerning it, and endeavour to fix its standard, we regard a new fact, to wit, the general taste of mankind, or some such fact, which may be the object of reasoning and enquiry.11

Is-ought divide

The end of section 3.1.1 from Hume’s Treatise of Human Nature, “Moral distinctions not derived from reason”:

In every system of morality, which I have hitherto met with, I have always remarked, that the author proceeds for some time in the ordinary way of reasoning, and establishes the being of a God, or makes observations concerning human affairs; when of a sudden I am surprized to find, that instead of the usual copulations of propositions, is, and is not, I meet with no proposition that is not connected with an ought, or an ought not. This change is imperceptible; but is, however, of the last consequence. For as this ought, or ought not, expresses some new relation or affirmation, it is necessary that it should be observed and explained; and at the same time that a reason should be given, for what seems altogether inconceivable, how this new relation can be a deduction from others, which are entirely different from it. But as authors do not commonly use this precaution, I shall presume to recommend it to the readers; and am persuaded, that this small attention would subvert all the vulgar systems of morality, and let us see, that the distinction of vice and virtue is not founded merely on the relations of objects, nor is perceived by reason.13

Moral realism

Introduction

Plato:

What about someone who believes in beautiful things, but doesn’t believe in the beautiful itself and isn’t able to follow anyone who could lead him to the knowledge of it? Don’t you think he is living in a dream rather than a wakened state? Isn’t this dreaming: whether asleep or awake, to think that a likeness is not a likeness but rather the thing itself that it is like?

I certainly think that someone who does that is dreaming.

But someone who, to take the opposite case, believes in the beautiful itself, can see both it and the things that participate in it and doesn’t believe that the participants are it or that it itself is the participants—he is living in a dream or is he awake?

He’s very much awake.14

Discussion

Criticism

Moral naturalism

Introduction

Evolution of morals

Churchland:

Our moral behavior, while more complex than the social behavior of other animals, is similar in that it represents our attempt to manage well in the existing social ecology. … from the perspective of neuroscience and brain evolution, the routine rejection of scientific approaches to moral behavior based on Hume’s warning against deriving ought from is seems unfortunate, especially as the warning is limited to deductive inferences. … The truth seems to be that values rooted in the circuitry for caring—for well-being of self, offspring, mates, kin, and others—shape social reasoning about many issues: conflict resolutions, keeping the peace, defense, trade, resource distribution, and many other aspects of social life in all its vast richness.18

Criticism

Solzhenitsyn:

If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?34

Socialism

Shields:

Every one of us has been warmed by fires we did not build. Every one of us has drank from wells we did not dig.36

Make the most of your regrets; never smother your sorrow, but tend and cherish it till it comes to have a separate and integral interest. To regret deeply is to live afresh.38

My thoughts

Debating moral realism with Sean Carroll.

AMA question about naturalism and moral realism.

As a fellow physicist (experimenter with ATLAS) also with an interest in philosophy, I’m really impressed by your efforts to push naturalism and engage philosophers. I fully agree with your materialist and reductionist arguments, supporting that we do understand physics within the everyday regime, and this should inform our metaphysics, philosophy of mind, criticism of pseudoscience, etc. I also like that you emphasize emergence as being an important concept in explaining the nested emergent ontologies in chemistry, biology, economics, etc. My question is why you seem to draw a hard line that ethics and morality cannot be analyzed in the same way. You seem to entertain the criticisms that some people say of “scientism,” that there are some things (like ethics) to which the reductive program of science will not be able to explain. This strikes me as totally inconsistent with the thrust of reductionism and naturalism. I think there are reasonable explanations for why ethics emerge as a set of regularities and good strategies anytime you have groups of people. The constraints on ethics seem to be completely determined by the natural world, including the limits of resources, the needs of our physiology, the laws of probability and game theory, etc. There is no fundamental is/ought divide. “Ought” is a higher descriptive term we give to actions that bring out good situations, for which there are objective metrics, such as health and satisfaction. In this regard, I’m sympathetic with some utilitarians and what Sam Harris seems to be describing in the Moral Landscape. Why do you think emergence from natural laws can introduce new concepts like temperature, phase transitions, supply and demand, but not ethics?

Sean’s reply:

Ryan — Essentially, science is about describing the world, not passing judgment on it. Temperature, phase transitions, and supply and demand are all concepts that helps us understand what happens in the world. Morality is just a completely different endeavor. (Of course you can scientifically study how human beings actually behave — including what they judge to be “moral” — but that’s different than studying how they should behave.) Scientific claims can be judged by experiments, moral claims cannot.

TODO: Drafting a reply.

I know I’m a consequentialist and a moral realist, but those are broad categories.

There’s no unified or received view of the fact/value, descriptive/normative divide since Hume. But that doesn’t mean there aren’t naturalistic philosophers that deny the dichotomy, i.e., would support the idea roughly that there is a scientific way of discussing and determining what is better. Health and nutrition seem like obvious plausible examples, really any reasoned strategy is normative: it tells one what one should do given what is known. In this sense many naturalists are aligned with game theoretic reasoning about what we should do.
