Ethics asks how people ought to act and what makes an obligation binding. Some early written evidence comes from societies where law, government and religion overlapped. A Babylonian king placed legal judgments beneath an image of a god. An Egyptian funerary papyrus pictured a person’s heart being weighed after death. Such sources document ways people explained responsibility. They leave the earliest history of human moral life open.

Justice in a royal inscription and a funerary papyrus
The stone monument known as the Code of Hammurabi was inscribed around 1750 BCE. At the top, the Babylonian king stands before Shamash, the sun god associated with justice. Below the relief is a collection of judgments. One set considers a poorly built house that collapses. If it kills the owner, the builder faces death. If it kills an enslaved person, the judgment requires the builder to compensate the owner with another enslaved person. The cases assign responsibility for a builder’s work and expose the unequal value the law placed on lives according to status. The relief gives the judgments a setting in which the king’s administration of justice stands under divine authority. The Louvre’s account of the monument · The judgments in translation, sections 229–232
A Ptolemaic Egyptian papyrus in the Metropolitan Museum of Art, dated to about 230–150 BCE, shows a different kind of judgment. Anubis weighs the dead person’s heart against a figure of Maat, who embodies the proper order of the cosmos. According to the museum’s description, the dead person also declares before a panel of judges that they have done no wrong. Here, the judgment concerns the conduct of a whole life and the deceased’s place in the world after death. The Met’s catalogue entry for the papyrus
How religious texts explain what people owe
In Deuteronomy, the command to keep the Sabbath extends rest to the household, including servants and resident foreigners. The passage recalls Israel’s enslavement in Egypt and deliverance by God. That memory is part of the reason given for the practice. A recurring religious observance places a limit on the work people may demand from those under their authority. Deuteronomy 5:12–15
Qur’an 4:135 speaks to the responsibility of a witness. It calls on believers to uphold justice even when testimony goes against their own interests or those of their parents or close relatives. It also warns against letting a person’s wealth or poverty sway the witness. The verse connects accountability to God with the practical problem of giving truthful evidence when loyalties pull in another direction. Qur’an 4:135
Other texts give different reasons for acting. In the Bhagavad Gita, Krishna tells Arjuna that carrying out one’s own dharma, here understood as one’s particular duty, takes precedence over performing someone else’s duty well. The Dhammapada asks a person to consider how others also fear violence and value their lives, then draws from that recognition an obligation to refrain from killing or causing others to kill. One passage directs attention to a duty proper to a person’s situation. The other starts from a vulnerability people can recognize in themselves and in others. Bhagavad Gita 3.35, 1972 translation and commentary · Dhammapada 129–130, translated by Ācāriya Buddharakkhita
What makes an act worthy of approval?
In Plato’s Euthyphro, a man is preparing to bring a charge against his father. He maintains that piety consists in what all the gods love. Socrates asks which comes first. Do the gods approve a holy act because it already has that quality, or does their approval make it holy? The immediate subject is piety. The distinction has a broader use in ethics because it asks whether approval creates a standard or responds to a standard that can itself be examined. Plato, Euthyphro 9a–11a
In the Analects, a passage on government asks how people come to take standards seriously. Confucius says that someone governed through punishments may learn to avoid penalties. Leadership by moral example, supported by rites and forms of conduct, can teach people to recognize when they fall short and correct themselves. This is a claim about moral formation. A rule can influence what people do in public, while repeated practice and example can influence how they judge their own conduct. Analects 2.3, Columbia University teaching edition
A false promise seen through duty, consequences and character
Suppose someone in financial difficulty asks for a loan and promises to repay it, already intending to keep the money. Immanuel Kant considers a similar example. He asks whether the rule that permits a false promise in a difficulty could apply to everyone. If people could make such promises as a general rule, the assurance on which this person relies would lose its meaning. Kant treats that as a problem of duty, even in a case where deceit might help the borrower. Kant, Groundwork, first section
John Stuart Mill’s utilitarian approach evaluates actions by their effects on happiness, which he explains in terms of pleasure and freedom from pain. Mill treats trust in what people say as a social good, so the harm of a false promise includes more than the immediate loss to the lender. Mill also considers circumstances in which withholding a truth could avert grave harm. A question drawn from Aristotle’s account of character is what habits people form by repeatedly acting in a certain way. On that approach, telling the truth in a difficult case is part of learning to act justly. The three lines of reasoning may support the same decision while bringing different features of the case into view. Mill, Utilitarianism, chapter II · Aristotle, Nicomachean Ethics, book II
Conclusion
Ancient inscriptions and religious texts preserve different accounts of who answers for a deed and why. Some place an obligation in a relationship with God, a remembered history or a particular role. Philosophical arguments examine duties, habits and the effects of acting. Comparing the reasons matters most when obligations come into conflict. A rule tells us what is expected, while the reason for it helps us judge what the obligation requires in a difficult case.
