The argument from morality is an argument for the existence of God. Arguments from morality tend to be based on moral normativity or moral order. Arguments from moral normativity observe some aspect of morality and argue that God is the best or only explanation for this, concluding that God must exist. Arguments from moral order are based on the asserted need for moral order to exist in the universe. They claim that, for this moral order to exist, God must exist to support it. The argument from morality is noteworthy in that one cannot evaluate the soundness of the argument without attending to almost every important philosophical issue in meta-ethics.
George Edward Moore was an English philosopher, who with Bertrand Russell, Ludwig Wittgenstein and earlier Gottlob Frege was among the initiators of analytic philosophy. He and Russell began de-emphasizing the idealism which was then prevalent among British philosophers and became known for advocating common-sense concepts and contributing to ethics, epistemology and metaphysics. He was said to have had an "exceptional personality and moral character". Ray Monk dubbed him "the most revered philosopher of his era".
Non-cognitivism is the meta-ethical view that ethical sentences do not express propositions and thus cannot be true or false. A noncognitivist denies the cognitivist claim that "moral judgments are capable of being objectively true, because they describe some feature of the world." If moral statements cannot be true, and if one cannot know something that is not true, noncognitivism implies that moral knowledge is impossible.
Secular humanism is a philosophy, belief system, or life stance that embraces human reason, logic, secular ethics, and philosophical naturalism, while specifically rejecting religious dogma, supernaturalism, and superstition as the basis of morality and decision-making.
Truth or verity is the property of being in accord with fact or reality. In everyday language, it is typically ascribed to things that aim to represent reality or otherwise correspond to it, such as beliefs, propositions, and declarative sentences.
Relativism is a family of philosophical views which deny claims to objectivity within a particular domain and assert that valuations in that domain are relative to the perspective of an observer or the context in which they are assessed. There are many different forms of relativism, with a great deal of variation in scope and differing degrees of controversy among them. Moral relativism encompasses the differences in moral judgments among people and cultures. Epistemic relativism holds that there are no absolute principles regarding normative belief, justification, or rationality, and that there are only relative ones. Alethic relativism is the doctrine that there are no absolute truths, i.e., that truth is always relative to some particular frame of reference, such as a language or a culture, while linguistic relativism asserts that a language's structures influence a speaker's perceptions. Some forms of relativism also bear a resemblance to philosophical skepticism. Descriptive relativism seeks to describe the differences among cultures and people without evaluation, while normative relativism evaluates the word truthfulness of views within a given framework.
In philosophy, rationalism is the epistemological view that "regards reason as the chief source and test of knowledge" or “the position that reason has precedence over other ways of acquiring knowledge”, often in contrast to other possible sources of knowledge such as faith, tradition, or sensory experience. More formally, rationalism is defined as a methodology or a theory "in which the criterion of truth is not sensory but intellectual and deductive".
Moral realism is the position that ethical sentences express propositions that refer to objective features of the world, some of which may be true to the extent that they report those features accurately. This makes moral realism a non-nihilist form of ethical cognitivism with an ontological orientation, standing in opposition to all forms of moral anti-realism and moral skepticism, including ethical subjectivism, error theory, and non-cognitivism. Moral realism's two main subdivisions are ethical naturalism and ethical non-naturalism.
The mere addition paradox is a problem in ethics identified by Derek Parfit and discussed in his book Reasons and Persons (1984). The paradox identifies the mutual incompatibility of four intuitively compelling assertions about the relative value of populations. Parfit’s original formulation of the repugnant conclusion is that "For any perfectly equal population with very high positive welfare, there is a population with very low positive welfare which is better, other things being equal."
The is–ought problem, as articulated by the Scottish philosopher and historian David Hume, arises when one makes claims about what ought to be that are based solely on statements about what is. Hume found that there seems to be a significant difference between descriptive statements and prescriptive statements, and that it is not obvious how one can coherently transition from descriptive statements to prescriptive ones.
In moral philosophy, instrumental and intrinsic value are the distinction between what is a means to an end and what is as an end in itself. Things are deemed to have instrumental value if they help one achieve a particular end; intrinsic values, by contrast, are understood to be desirable in and of themselves. A tool or appliance, such as a hammer or washing machine, has instrumental value because it helps one pound in a nail or clean clothes, respectively. Happiness and pleasure are typically considered to have intrinsic value insofar as asking why someone would want them makes little sense: they are desirable for their own sake irrespective of their possible instrumental value. The classic names instrumental and intrinsic were coined by sociologist Max Weber, who spent years studying good meanings people assigned to their actions and beliefs.
The fact–value distinction is a fundamental epistemological distinction described between:
- Statements of fact, which are based upon reason and observation, and examined via the empirical method.
- Statements of value, which encompass ethics and aesthetics, and are studied via axiology.

Language, Truth and Logic is a 1936 book about meaning by the philosopher Alfred Jules Ayer, in which the author defines, explains, and argues for the verification principle of logical positivism, sometimes referred to as the criterion of significance or criterion of meaning. Ayer explains how the principle of verifiability may be applied to the problems of philosophy. Language, Truth and Logic brought some of the ideas of the Vienna Circle and the logical empiricists to the attention of the English-speaking world.
Philosophy in the Tragic Age of the Greeks is an incomplete book by Friedrich Nietzsche. He had a clean copy made from his notes with the intention of publication. The notes were written around 1873. In it he discussed five Greek philosophers from the sixth and fifth centuries BC. They are Thales, Anaximander, Heraclitus, Parmenides, and Anaxagoras. He had, at one time, intended to include Democritus, Empedocles, and Socrates. The book ends abruptly after the discussion of Anaxagoras's cosmogony.
Secular ethics is a branch of moral philosophy in which ethics is based solely on human faculties such as logic, empathy, reason or moral intuition, and not derived from belief in supernatural revelation or guidance—a source of ethics in many religions. Secular ethics refers to any ethical system that does not draw on the supernatural, and includes humanism, secularism and freethinking. A classical example of literature on secular ethics is the Kural text, authored by the ancient Indian philosopher Valluvar.
The philosophy of Søren Kierkegaard has been a major influence in the development of 20th-century philosophy, especially existentialism and postmodernism. Søren Kierkegaard was a 19th-century Danish philosopher who has been labeled by many as the "Father of Existentialism", although there are some in the field who express doubt in labeling him an existentialist to begin with. His philosophy also influenced the development of existential psychology.
Hellenistic philosophy is Ancient Greek philosophy corresponding to the Hellenistic period in Ancient Greece, from the death of Alexander the Great in 323 BC to the Battle of Actium in 31 BC. The dominant schools of this period were the Stoics, the Epicureans and the Skeptics.
The following outline is provided as an overview of and topical guide to atheism:
Philosophical pessimism is a philosophical tradition which argues that life is not worth living and that non-existence is preferable to existence. Thinkers in this tradition emphasize that suffering outweighs pleasure, happiness is fleeting or unattainable, and existence itself does not hold inherent value or an intrinsic purpose. Philosophers such as Arthur Schopenhauer suggest responses to life's suffering, ranging from artistic contemplation and ascetic withdrawal, while Buddhism advocates for spiritual practices. Pessimism often addresses the ethics of both creating and continuing life. Antinatalists assert that bringing new life into a world of suffering is morally wrong, and some pessimists view suicide as a rational response in extreme circumstances; though Schopenhauer personally believed it failed to address the deeper causes of one's suffering.
