Philosopher Simon Blackburn writes that "Although the morality of people and their ethics amounts to the same thing, there is a usage that restricts morality to systems such as that of Immanuel Kant, based on notions such as duty, obligation, and principles of conduct, reserving ethics for the more Aristotelian approach to practical reasoning, based on the notion of a virtue, and generally avoiding the separation of 'moral' considerations from other practical considerations.
"[9] In its descriptive sense, "morality" refers to personal or cultural values, codes of conduct or social mores that are observed to be accepted by a significant number of individuals (not necessarily all) in a society.
For example, universal prescriptivism is a universalist form of non-cognitivism which claims that morality is derived from reasoning about implied imperatives, and divine command theory and ideal observer theory are universalist forms of ethical subjectivism which claim that morality is derived from the edicts of a god or the hypothetical decrees of a perfectly rational being, respectively.
[14] She characterizes the latter as predominantly negative and proscriptive: it defines a person's territory, including his or her property and dependents, which is not to be damaged or interfered with.
Jonathan Haidt has noted[17] that experimental observation indicating an in-group criterion provides one moral foundation substantially used by conservatives, but far less so by liberals.
A 2014 PEW research study among several nations illuminates significant cultural differences among issues commonly related to morality, including divorce, extramarital affairs, homosexuality, gambling, abortion, alcohol use, contraceptive use, and premarital sex.
[21] Anthropologists from Oxford's Institute of Cognitive & Evolutionary Anthropology (part of the School of Anthropology & Museum Ethnography) analysed ethnographic accounts of ethics from 60 societies, comprising over 600,000 words from over 600 sources and discovered what they believe to be seven universal moral rules: help your family, help your group, return favours, be brave, defer to superiors, divide resources fairly, and respect others' property.
Some sociobiologists contend that the set of behaviors that constitute morality evolved largely because they provided possible survival or reproductive benefits (i.e. increased evolutionary success).
Biologists contend that all social animals, from ants to elephants, have modified their behaviors, by restraining immediate selfishness in order to improve their evolutionary fitness.
[24] On this view, moral codes are ultimately founded on emotional instincts and intuitions that were selected for in the past because they aided survival and reproduction (inclusive fitness).
Examples: the maternal bond is selected for because it improves the survival of offspring; the Westermarck effect, where close proximity during early years reduces mutual sexual attraction, underpins taboos against incest because it decreases the likelihood of genetically risky behaviour such as inbreeding.
Its function is typically to ensure a reliable supply of essential resources, especially for animals living in a habitat where food quantity or quality fluctuates unpredictably.
Of historical interest in psychology are the theories of psychoanalysts such as Sigmund Freud, who believe that moral development is the product of aspects of the super-ego as guilt-shame avoidance.
To begin with, the authors demonstrate that people in no less than 60 nations hold the belief that morality is deteriorating continuously, and this conviction has been present for the last 70 years.
[38] In these experiments putatively moral versus nonmoral stimuli are compared to each other, while controlling for other variables such as content or working memory load.
Nonetheless, certain cognitive skills such as being able to attribute mental states—beliefs, intents, desires, emotions to oneself, and others is a common feature of a broad range of prototypical situations.
Moral intuition involves the fast, automatic, and affective processes that result in an evaluative feeling of good-bad or like-dislike, without awareness of going through any steps.
[44] Cognitive neuroscientist Jean Decety thinks that the ability to recognize and vicariously experience what another individual is undergoing was a key step forward in the evolution of social behavior, and ultimately, morality.
[48][49] Recently, drawing on empirical research in evolutionary theory, developmental psychology, social neuroscience, and psychopathy, Jean Decety argued that empathy and morality are neither systematically opposed to one another, nor inevitably complementary.
The explicit making of moral right and wrong judgments coincides with activation in the ventromedial prefrontal cortex (VMPC), a region involved in valuation, while intuitive reactions to situations containing implicit moral issues activates the temporoparietal junction area, a region that plays a key role in understanding intentions and beliefs.
A 2022 study conducted by scholars Michael Zakharin and Timothy C. Bates, and published by the European Journal of Personality, found that moral foundations have significant genetic bases.
[17][62] Haidt found that Americans who identified as liberals tended to value care and fairness higher than loyalty, respect and purity.
Haidt also hypothesizes that the origin of this division in the United States can be traced to geo-historical factors, with conservatism strongest in closely knit, ethnically homogeneous communities, in contrast to port-cities, where the cultural mix is greater, thus requiring more liberalism.
The continued existence of a group may depend on widespread conformity to codes of morality; an inability to adjust moral codes in response to new challenges is sometimes credited with the demise of a community (a positive example would be the function of Cistercian reform in reviving monasticism; a negative example would be the role of the Dowager Empress in the subjugation of China to European interests).
"[66] Within the wide range of moral traditions, religious value-systems co-exist with contemporary secular frameworks such as consequentialism, freethought, humanism, utilitarianism, and others.
For example, within Buddhism, the intention of the individual and the circumstances should be accounted for in the form of merit, to determine if an action is termed right or wrong.
[67] Barbara Stoler Miller points out a further disparity between the values of religious traditions, stating that in Hinduism, "practically, right and wrong are decided according to the categories of social rank, kinship, and stages of life.
For modern Westerners, who have been raised on ideals of universality and egalitarianism, this relativity of values and obligations is the aspect of Hinduism most difficult to understand".
Philosopher David Hume stated that "the greatest crimes have been found, in many instances, to be compatible with a superstitious piety and devotion; Hence it is justly regarded as unsafe to draw any inference in favor of a man's morals, from the fervor or strictness of his religious exercises, even though he himself believe them sincere.
[74] Christian apologists address Blackburn's viewpoints[75] and construe that Jewish laws in the Hebrew Bible showed the evolution of moral standards towards protecting the vulnerable, imposing a death penalty on those pursuing slavery and treating slaves as persons and not as property.
