    SOCRATES' INVOLVEMENT IN ETHICS

    One of the most intriguing paradoxes he helped his students investigate was the existence of willpower weakness — doing wrong when you sincerely knew what was right. He appeared to believe otherwise: people only did evil when the perceived benefits seemed to outweigh the costs at the time. As a result, mastering what he called "the art of measurement," rectifying the errors that skew one's analyses of benefit and cost, is central to the formation of personal ethics.
  • Period: 469 BCE to 399 BCE

    SOCRATES

    “No one commits an evil act knowingly and doing wrong arises
    out of ignorance.”
  • PLATO'S INVOLVEMENT IN ETHICS
    428 BCE

    PLATO'S INVOLVEMENT IN ETHICS

    Plato's main concern is to challenge most people's views on goodness because it is here that they go disastrously wrong in their attempts to live happy lives. Most people consider virtue to be a minor benefit, if not an impediment to living a happy life.
  • Period: 428 BCE to 348 BCE

    PLATO

    "It is only by being virtuous that we can hope to be happy."
  • ARISTOTLE'S CONTRIBUTION TO ETHICS
    384 BCE

    ARISTOTLE'S CONTRIBUTION TO ETHICS

    Aristotle argued that virtues are good habits that we acquire, which regulate our emotions. Aristotle further argued that most virtues fall at a mean between extreme character traits. Thus, in everything that we do, we must avoid extremes. This principle can also be used in determining and planning for profit in business, for example, too much profit results in greed, no profit results in bankruptcy.
  • Period: 384 BCE to 322 BCE

    ARISTOTLE

    Aristotle’s “The Golden Mean Principle” states that to be happy, live a life of moderation.
  • MORAL POSITIVISM

    MORAL POSITIVISM

    Hobbes' moral positivism implies a chaotic conclusion if laws are not followed. We all think that the government's role is to protect the rights of its citizens, uphold justice, and enforce the law. Thus, every country must have someone in charge of managing and administering its affairs.

    THOMAS HOBBES

    "People would act on their evil impulses if left alone for themselves; therefore, they should not be trusted to make decisions on their own.
  • UTILITARIANISM

    UTILITARIANISM

    “Do whatever produces the greatest good for the greatest number.” Utilitarianism is the objection that it assays no good or evil in acts themselves, but only in the good or evil that these acts produce.

    JUSTICE THEORY

    Theory of Justice holds that every individual has an equal right to basic liberties and that they should have the right to opportunities and an equal chance as other individuals of similar ability.
  • Period: to

    JOHN RAWLS

    Rawls insisted human justice must be centred on a firm foundation comprising a first and second principle. The first principle declared that “each person is to have an equal right to the most extensive basic liberty compatible with a similar liberty for others.” The second principle consisted of two sub-points: The difference principle and Fair equality of opportunity.
