The Moral Landscape


The Moral Landscape: How Science Can Determine Human Values is a 2010 book by Sam Harris, in which the author promotes a science of morality and argues that many thinkers have long confused the relationship between morality, facts, and science. He aims to carve a third path between secularists who say morality is subjective, and religionists who say that morality is given by God and scripture. Harris contends that the only moral framework worth talking about is one where "morally good" things pertain to increases in the "well-being of conscious creatures". He then argues that, problems with philosophy of science and reason in general notwithstanding, 'moral questions' will have objectively right and wrong answers which are grounded in empirical facts about what causes people to flourish.
Challenging the traditional philosophical notion that humans can never get an 'ought' from an 'is', Harris argues that moral questions are best pursued using not just philosophy, but the methods of science. Thus, "science can determine human values" translates to "science can tell us which values lead to human flourishing". It is in this sense that Harris advocates that scientists begin conversations about a normative science of "morality".
Publication of the book followed Harris's 2009 receipt of a Ph.D. in cognitive neuroscience from the University of California, Los Angeles with a similarly titled thesis: The moral landscape: How science could determine human values.

Synopsis

Sam Harris's case starts with two premises: " some people have better lives than others, and these differences are related, in some lawful and not entirely arbitrary way, to states of the human brain and to states of the world". The idea is that a person is simply describing material facts when they describe possible "better" and "worse" lives for themselves. Granting this, Harris says we must conclude that there are facts about which courses of action will allow one to pursue a better life.
Harris attests to the importance of admitting that such facts exist, because he says this logic applies to groups of individuals as well. He suggests that there are better and worse ways for whole societies to pursue better lives. Just like at the scale of the individual, there may be multiple different paths and "peaks" to flourishing for societies—and many more ways to fail.
Harris then makes a case that science could usefully define "morality" according to such facts. Often his arguments point out that problems with this scientific definition of morality seem to be problems shared by all science, or reason and words in general. Harris also spends some time describing how science might engage nuances and challenges of identifying the best ways for individuals, and groups of individuals, to improve their lives. Many of these issues are covered below.

Philosophical case

Although Harris's book discusses the challenges that a science of morality must face, he also mentions that his scientific argument is indeed philosophical. Furthermore, he says that this is the case for almost all scientific investigation. He mentions that modern science amounts to careful practice of accepted first philosophical principles like empiricism and physicalism. He also suggests that science has already very much settled on values in answering the question "what should I believe, and why should I believe it?". Harris says it should not be surprising that normative ethical sciences are, or would be, similarly founded on bedrock assumptions. Harris says:
The way he thinks science might engage moral issues draws on various philosophical positions like ethical realism, and ethical naturalism. Harris says a science of morality may resemble utilitarianism, but that the science is, importantly, more open-ended because it involves an evolving definition of well-being. Rather than committing to reductive materialism, then, Harris recognizes the arguments of revisionists that psychological definitions themselves are contingent on research and discoveries. Harris adds that any science of morality must consider everything from emotions and thoughts to the actual actions and their consequences.
To Harris, moral propositions, and explicit values in general, are concerned with the flourishing of conscious creatures in a society. He argues that "Social morality exists to sustain cooperative social relationships, and morality can be objectively evaluated by that standard." Harris sees some philosophers' talk of strictly private morality as akin to unproductive discussion of some private, personal physics. "If philosophers want to only talk about some bizarrely unnatural private morality, they are just changing the subject..."
Harris also discusses how interchangeability of perspective might emerge as an important part of moral reasoning. He alludes to an 'unpleasant surprise principle', where someone realizes they have been supporting an ineffective moral norm.

Science and moral truths

Harris identifies three projects for science as it relates to morality: explaining why humans do what they do in the name of "morality", determining which patterns of thought and behaviour humans actually should follow, and generally persuading humans to change their ways. Harris says that the first project is focused only on describing what is, whereas projects and are focused on what should and could be, respectively. Harris's point is that this second, prescriptive project should be the focus of a science of morality. He mentions, however, that we should not fear an "Orwellian future" with scientists at every door—vital progress in the science of morality could be shared in much the same way as advances in medicine.
Harris says it is important to delineate project from project, or else we risk committing a moralistic fallacy. He also highlights the importance of distinguishing between project from project . He says we must realize that the nuances of human motivation is a challenge in itself; humans often fail to do what they "ought" to do even to be successfully selfish—there is every reason to believe that discovering what is best for society would not change every member's habits overnight.
Harris does not imagine that people, even scientists, have always made the right moral decisions—indeed it is precisely his argument that many of them are wrong about moral facts. This is due to the many real challenges of good science in general, including human cognitive limitations and biases. He mentions the research of Paul Slovic and others to describe just a few of these established mental heuristics that might keep us from reasoning properly. Although he mentions that training might temper the influence of these biases, Harris worries about research showing that incompetence and ignorance in a domain leads to confidence.
Harris explains that debates and disagreement are a part of the scientific method, and that one side can certainly be wrong. He also explains that all the debates still available to science illustrate how much work could still be done, and how much conversation must continue.

Harris's positive beliefs

The book is full of issues that Harris thinks are far from being empirically, morally grey areas. That is, besides saying that 'reasonable' thinking about moral issues amounts to scientific thinking. For instance, he references one poll that found that 36 percent of British Muslims think apostates should be put to death for their unbelief, and he says that these individuals are "morally confused". He also suggests it is obvious that loneliness, helplessness, and poverty are "bad", but that these are by no means as far as positive psychology has taken, and will take us.
In one section, called The illusion of free will, Harris argues that there is a wealth of evidence in psychology or specifically related to the neuroscience of free will that suggests that metaphysically free will does not exist. This, he thinks, is intuitive; "trains of thought...convey the apparent reality of choices, freely made. But from a deeper perspective...thoughts simply arise ". He adds "The illusion of free will is itself an illusion". The implications of free will's non-existence may be a working determinism, and Harris warns us not to confuse this with fatalism.
One implication of a determined will, Harris says, is that it becomes unreasonable to punish people out of retribution—only behaviour modification and the deterrence of others still seem to be potentially valid reasons to punish. This, especially because behaviour modification is a sort of cure for the evil behaviours; Harris provides a thought experiment:
Harris acknowledges a hierarchy of moral consideration. He says it follows that there could, in principle, be a species compared to which we are relatively unimportant.
Harris supports the development of lie-detection technology and believes it would be, on the whole, beneficial for humanity.

Religion: good or bad?

Consistent with Harris's definition of morality, he says we must ask whether religion increases human flourishing today. He argues that religions may largely be practiced because they fit well with human cognitive tendencies.
In Harris's view, religion and religious dogma is an impediment to reason, and he discusses the views of Francis Collins as one example.
Harris criticizes the tactics of secularists like Chris Mooney, who argue that science is not fundamentally in conflict with religion. Harris sees this as a very serious disagreement, that patronizingly attempts to pacify more devout theists. Harris claims that societies can move away from deep dependence on religion just as it has from witchcraft, which he says was once just as deeply ingrained.

Promotion

In advance of publication, four personal and professional acquaintances of the author offered their praise for the book, including biologist and science popularizer Richard Dawkins, novelist Ian McEwan, psycholinguist Steven Pinker, and theoretical physicist Lawrence Krauss. They each serve on the Advisory Board of Harris's Project Reason, and their praise appears as blurbs.
Dawkins said,
McEwan wrote that "Harris breathes intellectual fire into an ancient debate. Reading this thrilling, audacious book, you feel the ground shifting beneath your feet. Reason has never had a more passionate advocate." Pinker said that Harris offers "a tremendously appealing vision, and one that no thinking person can afford to ignore." Krauss opined that Harris "has the rare ability to frame arguments that are not only stimulating, they are downright nourishing, even if you don't always agree with him!" Krauss predicted that "readers are bound to come away with previously firm convictions about the world challenged, and a vital new awareness about the nature and value of science and reason in our lives."

Reception

The Moral Landscape reached 9th in The New York Times Best Seller list for Hardcover Non-Fiction in October 2010.

Reviews and criticism

Associate Professor of Philosophy James W. Diller and Andrew E. Nuzzolilli wrote a generally favorable review in a journal of the Association for Behavior Analysis International:
In his review for Barnes & Noble, Cal State Associate Professor of Philosophy Troy Jollimore wrote that the book "has some good, reasonable, and at times persuasive things to say" to people who are unfamiliar with moral skepticism, but "has little to say to those people who actually do know what the arguments are, and it will not help others become much better informed." Jollimore also worried that Harris wrongly presents complex issues as having simple solutions.
Kwame Anthony Appiah wrote in The New York Times "when stays closest to neuroscience, he says much that is interesting and important...". He later criticized Harris for failing to articulate "his central claim" and to identify how science has "revealed" that human well-being has an objective component. Appiah argued that Harris "ends up endorsing... something very like utilitarianism, a philosophical position that is now more than two centuries old,... that faces a battery of familiar problems," which Harris merely "push... aside." Harris responded to Appiah in the afterword of the paperback version, claiming that all of Appiah's criticisms had already been addressed in the chapter "Good and Evil".
Cognitive anthropologist Scott Atran criticized Harris for failing to engage with the philosophical literature on ethics and the problems in attempting to scientifically quantify human well being, noting that
Critiquing the book, Kenan Malik wrote:
David Sexton of the London Evening Standard described Harris's claim to provide a science of morality as "the most extraordinarily overweening claim and evidently flawed. Science does not generate its own moral values; it can be used for good or ill and has been. Harris cannot stand outside culture, and the 'better future' he prophesies is itself a cultural projection. "
John Horgan, journalist for the Scientific American blog and author of The End of Science, wrote "Harris further shows his arrogance when he claims that neuroscience, his own field, is best positioned to help us achieve a universal morality.... Neuroscience can't even tell me how I can know the big, black, hairy thing on my couch is my dog Merlin. And we're going to trust neuroscience to tell us how we should resolve debates over the morality of abortion, euthanasia and armed intervention in other nations' affairs?"
Russell Blackford said "The Moral Landscape is an ambitious work that will gladden the hearts, and strengthen the spines, of many secular thinkers" but that he nonetheless had "serious reservations” about the book.
The philosopher Simon Blackburn, reviewing the book, described Harris as "a knockabout atheist" who "joins the prodigious ranks of those whose claim to have transcended philosophy is just an instance of their doing it very badly", pointing out that "if Bentham's hedonist is in one brain state and Aristotle's active subject is in another, as no doubt they would be, it is a moral, not an empirical, problem to say which is to be preferred." And H. Allen Orr in The New York Review of Books finds that "despite Harris's bravado about 'how science can determine human values,' The Moral Landscape delivers nothing of the kind."
Steve Isaacson wrote Mining The Moral Landscape: Why Science Does Not Determine Human Values. Isaacson concludes, "The largest objection to Harris' argument is still Moore's open-question argument. Harris dismisses the argument as a word game easily avoided, but he never explains the game nor how to avoid it. He just ignores it."
American novelist Marilynne Robinson, writing in The Wall Street Journal, asserted that Harris fails to "articulate a positive morality of his own" but, had he done so, would have found himself in the company of the "Unitarians, busily cooperating on schemes to enhance the world's well being, as they have been doing for generations."
At the Moving Naturalism Forward workshop, Nobel Prize-winning physicist Steven Weinberg described how in his youth he had been a utilitarian but had been dissuaded of the notion that "the fundamental principle that guides our actions should be the greatest happiness for the greatest number" by reading Aldous Huxley's Brave New World. Weinberg went on to say: "Now, Sam Harris is aware of this kind of counter argument , and says it's not happiness, it's human welfare. Well, as you make things vaguer and vaguer, of course, it becomes harder and harder to say it doesn't fit your own moral feelings, but it also becomes less and less useful as a means of making moral judgements. You could take that to the extreme and make up some nonsense word and say that's the important thing and no one could refute it, but it wouldn't be very helpful. I regard human welfare and the way Sam Harris refers to it as sort of halfway in that direction to absolute nonsense."

Response to critics from Harris

A few months after the book's release, Harris wrote a follow-up at The Huffington Post responding to his critics.
On August 31, 2013, in response to the negative reviews of his book, Harris issued a public challenge for anyone to write an essay of less than 1,000 words rebutting the "central argument" of the book. The submissions were vetted by Russell Blackford, with the author of the essay judged best to receive $2,000, or $20,000 if they succeeded in changing Harris's mind. Four hundred and twenty-four essays were received by the deadline. On March 11, 2014, Blackford announced the winning essay was written by philosophy instructor Ryan Born.
