Ethics is the philosophical study of moral phenomena. Also called moral philosophy, it investigates normative questions about what people ought to do or which behavior is morally right. Its main branches include normative ethics, applied ethics, and metaethics.
Hedonism is a family of philosophical views that prioritize pleasure. Psychological hedonism is the theory that the underlying motivation of all human behavior is to maximize pleasure and avoid pain. As a form of egoism, it suggests that people only help others if they expect a personal benefit. Axiological hedonism is the view that pleasure is the sole source of intrinsic value. It asserts that other things, like knowledge and money, only have value insofar as they produce pleasure and reduce pain. This view divides into quantitative hedonism, which only considers the intensity and duration of pleasures, and qualitative hedonism, which holds that the value of pleasures also depends on their quality. The closely related position of prudential hedonism states that pleasure and pain are the only factors of well-being. Ethical hedonism applies axiological hedonism to morality, arguing that people have a moral obligation to pursue pleasure and avoid pain. Utilitarian versions assert that the goal is to increase overall happiness for everyone, whereas egoistic versions state that each person should only pursue their own pleasure. Outside the academic context, hedonism is a pejorative term for an egoistic lifestyle seeking short-term gratification.
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.
Peter Albert David Singer is an Australian moral philosopher who is Emeritus Ira W. DeCamp Professor of Bioethics at Princeton University. Singer's work specialises in applied ethics, approaching the subject from a secular, utilitarian perspective. He wrote the book Animal Liberation (1975), in which he argues for vegetarianism, and the essay "Famine, Affluence, and Morality", which argues the moral imperative of donating to help the poor around the world. For most of his career, he was a preference utilitarian. He revealed in The Point of View of the Universe (2014), coauthored with Katarzyna de Lazari-Radek, that he had become a hedonistic utilitarian.
In ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for the affected individuals. In other words, utilitarian ideas encourage actions that lead to the greatest good for the greatest number. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described utility as the capacity of actions or objects to produce benefits, such as pleasure, happiness, and good, or to prevent harm, such as pain and unhappiness, to those affected.
Virtue ethics is a philosophical approach that treats virtue and character as the primary subjects of ethics, in contrast to other ethical systems that put consequences of voluntary acts, principles or rules of conduct, or obedience to divine authority in the primary role.

Pragmatic ethics is a theory of normative philosophical ethics and meta-ethics. Ethical pragmatists such as John Dewey believe that some societies have progressed morally in much the way they have attained progress in science. Scientists can pursue inquiry into the truth of a hypothesis and accept the hypothesis, in the sense that they act as though the hypothesis were true; nonetheless, they think that future generations can advance science, and thus future generations can refine or replace their accepted hypotheses. Similarly, ethical pragmatists think that norms, principles, and moral criteria are likely to be improved as a result of inquiry.
