EpicurusEpicurus (ˌɛpɪˈkjʊərəs, ; Ἐπίκουρος ; 341–270 BC) was an ancient Greek philosopher and sage who founded Epicureanism, a highly influential school of philosophy. He was born on the Greek island of Samos to Athenian parents. Influenced by Democritus, Aristippus, Pyrrho, and possibly the Cynics, he turned against the Platonism of his day and established his own school, known as "the Garden", in Athens. Epicurus and his followers were known for eating simple meals and discussing a wide range of philosophical subjects.
Psychological egoismPsychological egoism is the view that humans are always motivated by self-interest and selfishness, even in what seem to be acts of altruism. It claims that, when people choose to help others, they do so ultimately because of the personal benefits that they themselves expect to obtain, directly or indirectly, from so doing. This is a descriptive rather than normative view, since it only makes claims about how things are, not how they “ought to be” according to some.
EudaimoniaEudaimonia (Greek: εὐδαιμονία eu̯dai̯moníaː; juːdɪˈmoʊniə), sometimes anglicized as eudaemonia or eudemonia, is a Greek word literally translating to the state or condition of 'good spirit', and which is commonly translated as 'happiness' or 'welfare'. In works of Aristotle, eudaimonia was the term for the highest human good in older Greek tradition. It is the aim of practical philosophy-prudence, including ethics and political philosophy, to consider and experience what this state really is, and how it can be achieved.
SocratesSocrates (ˈsɒkrətiːz; Σωκράτης; 470–399 BC) was a Greek philosopher from Athens who is credited as the founder of Western philosophy and among the first moral philosophers of the ethical tradition of thought. An enigmatic figure, Socrates authored no texts and is known mainly through the posthumous accounts of classical writers, particularly his students Plato and Xenophon. These accounts are written as dialogues, in which Socrates and his interlocutors examine a subject in the style of question and answer; they gave rise to the Socratic dialogue literary genre.
VirtueA virtue (virtus) is a trait of excellence, including traits that may be moral, social, or intellectual. The cultivation and refinement of virtue is held to be the "good of humanity" and thus is valued as an end purpose of life or a foundational principle of being. In human practical ethics, a virtue is a disposition to choose actions that succeed in showing high moral standards: doing what is right and avoiding what is wrong in a given field of endeavour.
Ethical naturalismEthical naturalism (also called moral naturalism or naturalistic cognitivistic definism) is the meta-ethical view which claims that: Ethical sentences express propositions. Some such propositions are true. Those propositions are made true by objective features of the world. These moral features of the world are reducible to some set of non-moral features. The versions of ethical naturalism which have received the most sustained philosophical interest, for example, Cornell realism, differ from the position that "the way things are is always the way they ought to be", which few ethical naturalists hold.
AxiologyAxiology (from Greek ἀξία, axia: "value, worth"; and -λογία, -logia: "study of") is the philosophical study of value. It includes questions about the nature and classification of values and about what kinds of things have value. It is intimately connected with various other philosophical fields that crucially depend on the notion of value, like ethics, aesthetics or philosophy of religion. It is also closely related to value theory and meta-ethics. The term was first used by Eduard von Hartmann in 1887 and by Paul Lapie in 1902.
SpeciesismSpeciesism (ˈspiːʃiːˌzɪzəm,_-siːˌzɪz-) is a term used in philosophy regarding the treatment of individuals of different species. The term has several different definitions within the relevant literature. Some sources specifically define speciesism as discrimination or unjustified treatment based on an individual's species membership, while other sources define it as differential treatment without regard to whether the treatment is justified or not.
Applied ethicsApplied ethics refers to the practical aspect of moral considerations. It is ethics with respect to real-world actions and their moral considerations in the areas of private and public life, the professions, health, technology, law, and leadership. For example, the bioethics community is concerned with identifying the correct approach to moral issues in the life sciences, such as euthanasia, the allocation of scarce health resources, or the use of human embryos in research.
Effective altruismEffective altruism is a philosophical and social movement that advocates "using evidence and reason to figure out how to benefit others as much as possible, and taking action on that basis". People who pursue the goals of effective altruism, called , often choose careers based on the amount of good that they expect the career to achieve or donate to charities based on the goal of maximising impact. The movement developed during the 2000s, and the name was coined in 2011.
