Science of morality (also known as science of ethics or scientific ethics) may refer to various forms of ethical naturalism grounding morality and ethics in rational, empirical consideration of the natural world. [1] It is sometimes framed as using the scientific approach to determine what is right and wrong, in contrast to the widespread belief that "science has nothing to say on the subject of human values". [2]
Moral science may refer to the consideration of what is best for, and how to maximize the flourishing of, either particular individuals[ citation needed ] or all conscious creatures. [3] [4] It has been proposed that "morality" can be appropriately defined on the basis of fundamental premises necessary for any empirical, secular, or philosophical discussion and that societies can use the methods of science to provide answers to moral questions. [5] [6]
The norms advocated by moral scientists (e.g. rights to abortion, euthanasia, and drug liberalization under certain circumstances) would be founded upon the shifting and growing collection of human understanding. [7] Even with science's admitted degree of ignorance, and the various semantic issues, moral scientists can meaningfully discuss things as being almost certainly "better" or "worse" for promoting flourishing. [8]
Utilitarian Jeremy Bentham discussed some of the ways moral investigations are a science. [9] He criticized deontological ethics for failing to recognize that it needed to make the same presumptions as his science of morality to really work – whilst pursuing rules that were to be obeyed in every situation (something that worried Bentham).
W. V. O. Quine advocated naturalizing epistemology by looking to natural sciences like psychology for a full explanation of knowledge.[ further explanation needed ] His work contributed to a resurgence of moral naturalism in the last half of the 20th century. Paul Kurtz, who believes that the careful, secular pursuit of normative rules is vital to society, coined the term eupraxophy to refer to his approach to normative ethics. Steven Pinker, Sam Harris, and Peter Singer believe that we learn what is right and wrong through reason and empirical methodology. [10] [11]
Maria Ossowska thought that sociology was inextricably related to philosophical reflections on morality, including normative ethics. She proposed that science analyse: (a) existing social norms and their history, (b) the psychology of morality, and the way that individuals interact with moral matters and prescriptions, and (c) the sociology of morality. [12]
The theory and methods of a normative science of morality are explicitly discussed in Joseph Daleiden's The Science of Morality: The Individual, Community, and Future Generations (1998). Daleiden's book, in contrast to Harris, extensively discusses the relevant philosophical literature. In The Moral Landscape: How Science Can Determine Human Values , Sam Harris's goal is to show how moral truth can be backed by "science", or more specifically, empirical knowledge, critical thinking, philosophy, but most controversially, the scientific method.
Patricia Churchland offers that, accepting David Hume's is–ought problem, the use of induction from premises and definitions remains a valid way of reasoning in life and science: [13]
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. [14]
Daleiden and Leonard Carmichael warn that science is probabilistic, and that certainty is not possible. One should therefore expect that moral prescriptions will change as humans gain understanding. [15] [note 1]
The science of morality may aim to discover the best ways to motivate and shape individuals. Methods to accomplish this include instilling explicit virtues, building character strengths, and forming mental associations. These generally require some level of practical reason. James Rest suggested that abstract reasoning is also a factor in making moral judgements [17] and emphasized that moral judgements alone do not predict moral behaviour: “Moral judgement may be closely related to advocacy behaviour, which in turn influences social institutions, which in turn creates a system of norms and sanctions that influences people’s behaviour.” [17] Daleiden suggested that religions instill a practical sense of virtue and justice, right and wrong. They also effectively use art and myths to educate people about moral situations. [18]
Harris argues that moral science does not imply an "Orwellian future" with "scientists at every door". Instead, Harris imagines data about normative moral issues being shared in the same way as other sciences (e.g. peer-reviewed journals on medicine). [19]
Daleiden specifies that government, like any organization, should have limited power. He says "centralization of power irrevocably in the hands of one person or an elite has always ultimately led to great evil for the human race. It was the novel experiment of democracy—a clear break with tradition—that ended the long tradition of tyranny.” [20] He is also explicit that government should only use law to enforce the most basic, reasonable, proven and widely supported moral norms. In other words, there are a great many moral norms that should never be the task of the government to enforce. [21]
One author has argued that to attain a society where people are motivated by conditioned self-interest, punishment must go hand-in-hand with reward. [22] For instance, in this line of reasoning, prison remains necessary for many perpetrators of crimes. This is so, even if libertarian free will is false. This is because punishment can still serve its purposes: it deters others from committing their own crimes, educates and reminds everyone about what the society stands for, incapacitates the criminal from doing more harm, goes some way to relieving or repaying the victim, and corrects the criminal (also see recidivism). This author argues that, at least, any prison system should be pursuing those goals, and that it is an empirical question as to what sorts of punishment realize these goals most effectively, and how well various prison systems actually serve these purposes. [23]
The brain areas that are consistently involved when humans reason about moral issues have been investigated. [24] The neural network underlying moral decisions overlaps with the network pertaining to representing others' intentions (i.e., theory of mind) and the network pertaining to representing others' (vicariously experienced) emotional states (i.e., empathy). This supports the notion that moral reasoning is related to both seeing things from other persons’ points of view and to grasping others’ feelings. These results provide evidence that the neural network underlying moral decisions is probably domain-global (i.e., there might be no such things as a "moral module" in the human brain) and might be dissociable into cognitive and affective sub-systems.
An essential, shared component of moral judgment involves the capacity to detect morally salient content within a given social context. Recent research implicated the salience network in this initial detection of moral content. [25] The salience network responds to behaviourally salient events, [26] [27] and may be critical to modulate downstream default and frontal control network interactions in the service of complex moral reasoning and decision-making processes. This suggest that moral cognition involves both bottom-up and top-down attentional processes, mediated by discrete large-scale brain networks and their interactions.
Moral sciences is offered at the degree level at Ghent University (as "an integrated empirical and philosophical study of values, norms and world views") [28]
Daleiden provides examples of how science can use empirical evidence to assess the effect that specific behaviours can have on the well-being of individuals and society with regard to various moral issues. He argues that science supports decriminalization and regulation of drugs, euthanasia under some circumstances, and the permission of sexual behaviours that are not tolerated in some cultures (he cites homosexuality as an example). Daleiden further argues that in seeking to reduce human suffering, abortion should not only be permissible, but at times a moral obligation (as in the case of a mother of a potential child who would face the probability of much suffering). Like all moral claims in his book, however, Daleiden is adamant that these decisions remain grounded in, and contingent on empirical evidence. [7] [note 2]
The ideas of cultural relativity, to Daleiden, do offer some lessons: investigators must be careful not to judge a person's behaviour without understanding the environmental context. An action may be necessary and more moral once we are aware of circumstances. [29] However, Daleiden emphasizes that this does not mean all ethical norms or systems are equally effective at promoting flourishing [29] and he often offers the equal treatment of women as a reliably superior norm, wherever it is practiced.
The idea of a normative science of morality has met with many criticisms from scientists and philosophers. Critics include physicist Sean M. Carroll, who argues that morality cannot be part of science. [30] He and other critics cite the widely held "fact-value distinction", that the scientific method cannot answer "moral" questions, although it can describe the norms of different cultures. In contrast, moral scientists defend the position that such a division between values and scientific facts ("moral relativism") is not only arbitrary and illusory, but impeding progress towards taking action against documented cases of human rights violations in different cultures. [31]
Stephen Jay Gould argued that science and religion occupy "non-overlapping magisteria". To Gould, science is concerned with questions of fact and theory, but not with meaning and morality – the magisteria of religion. In the same vein, Edward Teller proposed that politics decides what is right, whereas science decides what is true. [32]
During a discussion on the role that naturalism might play in professions like nursing, the philosopher Trevor Hussey calls the popular view that science is unconcerned with morality "too simplistic". Although his main focus in the paper is naturalism in nursing, he goes on to explain that science can, at very least, be interested in morality at a descriptive level. He even briefly entertains the idea that morality could itself be a scientific subject, writing that one might argue "... that moral judgements are subject to the same kinds of rational, empirical examination as the rest of the world: they are a subject for science – although a difficult one. If this could be shown to be so, morality would be contained within naturalism. However, I will not assume the truth of moral realism here." [note 3]
The argument from morality is an argument for the existence of God. Arguments from morality tend to be based on moral normativity or moral order. Arguments from moral normativity observe some aspect of morality and argue that God is the best or only explanation for this, concluding that God must exist. Arguments from moral order are based on the asserted need for moral order to exist in the universe. They claim that, for this moral order to exist, God must exist to support it. The argument from morality is noteworthy in that one cannot evaluate the soundness of the argument without attending to almost every important philosophical issue in meta-ethics.
Ethical naturalism is the meta-ethical view which claims that:
Jurisprudence, also known as theory of law or philosophy of law, is the examination in a general perspective of what law is and what it ought to be. It investigates issues such as the definition of law; legal validity; legal norms and values; as well as the relationship between law and other fields of study, including economics, ethics, history, sociology, and political philosophy.
In metaphilosophy and ethics, metaethics is the study of the nature, scope, ground, and meaning of moral judgment, ethical belief, or values. It is one of the three branches of ethics generally studied by philosophers, the others being normative ethics and applied ethics.
In metaethics, the naturalistic fallacy is the claim that it is possible to define good in terms of merely described entities, properties, or processes such as pleasant, desirable, or fitness. The term was introduced by British philosopher G. E. Moore in his 1903 book Principia Ethica.
Normative ethics is the study of ethical behaviour and is the branch of philosophical ethics that investigates questions regarding how one ought to act, in a moral sense.
Morality is the categorization of intentions, decisions and actions into those that are proper, or right, and those that are improper, or wrong. Morality can be a body of standards or principles derived from a code of conduct from a particular philosophy, religion or culture, or it can derive from a standard that is understood to be universal. Morality may also be specifically synonymous with "goodness", "appropriateness" or "rightness".
Moral relativism or ethical relativism is used to describe several philosophical positions concerned with the differences in moral judgments across different peoples and cultures. An advocate of such ideas is often referred to as a relativist.
Reflective equilibrium is a state of balance or coherence among a set of beliefs arrived at by a process of deliberative mutual adjustment among general principles and particular judgements. Although he did not use the term, philosopher Nelson Goodman introduced the method of reflective equilibrium as an approach to justifying the principles of inductive logic. The term reflective equilibrium was coined by John Rawls and popularized in his A Theory of Justice as a method for arriving at the content of the principles of justice.
Descriptive ethics, also known as comparative ethics, is the study of people's beliefs about morality. It contrasts with prescriptive or normative ethics, which is the study of ethical theories that prescribe how people ought to act, and with meta-ethics, which is the study of what ethical terms and theories actually refer to. The following examples of questions that might be considered in each field illustrate the differences between the fields:
The is–ought problem, as articulated by the Scottish philosopher and historian David Hume, arises when one makes claims about what ought to be that are based solely on statements about what is. Hume found that there seems to be a significant difference between descriptive statements and prescriptive statements, and that it is not obvious how one can coherently transition from descriptive statements to prescriptive ones.
A prescriptive or normative statement is one that evaluates certain kinds of words, decisions, or actions as either correct or incorrect, or one that sets out guidelines for what a person "should" do.
Applied philosophy is a branch of philosophy that studies philosophical problems of practical concern. The topic covers a broad spectrum of issues in environment, medicine, science, engineering, policy, law, politics, economics and education. The term was popularised in 1982 by the founding of the Society for Applied Philosophy by Brenda Almond, and its subsequent journal publication Journal of Applied Philosophy edited by Elizabeth Brake. Methods of applied philosophy are similar to other philosophical methods including questioning, dialectic, critical discussion, rational argument, systematic presentation, thought experiments and logical argumentation.
Evolutionary ethics is a field of inquiry that explores how evolutionary theory might bear on our understanding of ethics or morality. The range of issues investigated by evolutionary ethics is quite broad. Supporters of evolutionary ethics have argued that it has important implications in the fields of descriptive ethics, normative ethics, and metaethics.
Metaepistemology is the branch of epistemology and metaphilosophy that studies the underlying assumptions made in debates in epistemology, including those concerning the existence and authority of epistemic facts and reasons, the nature and aim of epistemology, and the methodology of epistemology.
Secular ethics is a branch of moral philosophy in which ethics is based solely on human faculties such as logic, empathy, reason or moral intuition, and not derived from belief in supernatural revelation or guidance—a source of ethics in many religions. Secular ethics refers to any ethical system that does not draw on the supernatural, and includes humanism, secularism and freethinking. A classical example of literature on secular ethics is the Kural text, authored by the ancient Indian philosopher Valluvar.
The following outline is provided as an overview of and topical guide to ethics.
The Moral Landscape: How Science Can Determine Human Values is a 2010 book by Sam Harris, in which he 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 dictated by God and scripture.
Dual process theory within moral psychology is an influential theory of human moral judgement that posits that human beings possess two distinct cognitive subsystems that compete in moral reasoning processes: one fast, intuitive and emotionally-driven, the other slow, requiring conscious deliberation and a higher cognitive load. Initially proposed by Joshua Greene along with Brian Sommerville, Leigh Nystrom, John Darley, Jonathan David Cohen and others, the theory can be seen as a domain-specific example of more general dual process accounts in psychology, such as Daniel Kahneman's "system1"/"system 2" distinction popularised in his book, Thinking, Fast and Slow. Greene has often emphasized the normative implications of the theory, which has started an extensive debate in ethics.
A legal norm is a binding rule or principle, or norm, that organisations of sovereign power promulgate and enforce in order to regulate social relations. Legal norms determine the rights and duties of individuals who are the subjects of legal relations within the governing jurisdiction at a given point in time. Competent state authorities issue and publish basic aspects of legal norms through a collection of laws that individuals under that government must abide by, which is further guaranteed by state coercion. There are two categories of legal norms: normativity, which regulates the conduct of people, and generality, which is binding on an indefinite number of people and cases. Diplomatic and legislative immunity refers to instances where legal norms are constructed to be targeted towards a minority and are specifically only binding on them, such as soldiers and public officials.
Casting morality as a maximization problem might seem overly restrictive at first glance, but the procedure can potentially account for a wide variety of approaches. A libertarian might want to maximize a feeling of personal freedom, while a traditional utilitarian might want to maximize some version of happiness. The point is simply that the goal of morality should be to create certain conditions that are, in principle, directly measurable by empirical means. ...Nevertheless, I want to argue that this program is simply not possible. ... Morality is not part of science, however much we would like it to be. There are a large number of arguments one could advance for in support of this claim, but I'll stick to three.
There are also very practical, moral concerns that follow from the glib idea that anyone is free to value anything—the most consequential being that it is precisely what allows highly educated, secular, and otherwise well-intentioned people to pause thoughtfully, and often interminably, before condemning practices like compulsory veiling, genital excision, bride-burning, forced marriage, and the other cheerful products of alternative "morality" found elsewhere in the world. Fanciers of Hume's is/ought distinction never seem to realize what the stakes are, and they do not see what an abject failure of compassion their intellectual "tolerance" of moral difference amounts to. While much of this debate must be had in academic terms, this is not merely an academic debate. There are women and girls getting their faces burned off with acid at this moment for daring to learn to read, or for not consenting to marry men they have never met, or even for the crime of getting raped.
