The content of a declarative sentence employed in its typical use; a proposition.
A symbol (usually uppercase letters such as A, B, C, etc.) used to represent a specific simple statement in the propositional calculus.
In the propositional calculus, a string of symbols including only statement variables, and connectives (along with parenthetical punctuation) such that the substitution of a statement for each of its variables would result in a well-formed compound statement.
A symbol (usually lowercase letters such as p, q, r, s, etc.) used to represent any statement whatsoever in the propositional calculus.
American philosopher. Stevenson's "The Emotive Meaning of Ethical Terms" (1937), "Persuasive Definitions" (1938), and Ethics and Language (1944) developed emotivism as a meta-ethical theory in which moral judgments invariably express and encourage human feelings of characteristic sorts. His papers are collected in Facts and Values (1963).

The arbitrary assignment of meaning to a term not previously in use. Although it may be relatively inconvenient or useless, such a definition can never be mistaken or incorrect.
School of philosophy organized at Athens in the third century B.C.E. by Zeno of Citium and Chrysippus. The stoics provided a unified account of the world that comprised formal logic, materialistic physics, and naturalistic ethics. Later Roman stoics, including Seneca, Epictetus, and Marcus Aurelius, emphasized more exclusively the development of recommendations for living in harmony with a natural world over which one has no direct control.

British philosopher who applies the methods of analytic philosophy to traditional philosophical problems. Strawson criticized Russell's theory of descriptions in "On Referring" (1950) and developed the notion of descriptive (as opposed to revisionary) metaphysics in reference to problem of reidentification of particulars in Individuals: An Essay in Descriptive Metaphysics (1959). His The Bounds of Sense (1966) is an extended commentary on the critical philosophy of Kant.

Method of interpreting social phenomena in the context of a system of signs whose significance lies solely in the interrelationships among them. Initiated in the linguistics of Saussure and Chomsky, structuralism was applied to other disciplines by Lévi-Strauss, Piaget, Althusser, Lacan, Barthes, Foucault, and Eco. Most structuralists share a conviction that individual human beings function solely as elements of the (often hidden) social networks to which they belong.

Palmer, Structuralism and Poststructuralism for Beginners (Writers & Readers, 2001).
Spanish philosopher and theologian whose rejection of Aristotelian authority in the Disputationes Metaphysicae (Metaphysical Disputations) (1597) became a significant component of much Renaissance thinking. In De legibus ac Deo legislatore (On Law) (1612) Suárez qualified the natural law theory of Aquinas, defending instead a voluntaristic notion of the effect of legislative edicts.

In the traditional square of opposition, the relationship between a universal propositioin and its corresponding particular proposition. Thus, an I is the subaltern of its A proposition, and an O is the subaltern of its E proposition. Thus, for example:
Some larks are birds is subaltern to All larks are birds, and
Some robins are not fish is subaltern to No robins are fish.
Subalternation is a reliable pattern of inference only on the assumption of existential import for universal propositions.
A pair of categorical propositions which (provided that we assume existential import) cannot both be false, although both could be true. In the traditional square of opposition, an I proposition and its corresponding O are subcontraries. Thus, for example:
Some business leaders are women and Some business leaders are not women
That which depends upon the personal or individual, especially wherein contrast with the objectiveit is supposed to be an arbitrary expression of private taste.

The aesthetic feeling aroused by experiences too overwhelming in scale to be appreciated as beautiful by the senses. The awe produced by standing on the brink of the Grand Canyon or the terror induced by witnessing a hurricane are properly said to be sublime.

Latin for "under the aspect of eternity;" hence, from Spinoza onwards, an honorific expression describing what is universally and eternally true, without any reference to or dependance upon the merely temporal portions of reality.
What a thing is made of; hence, the underlying being that supports, exists independently of, and persists through time despite changes in, its accidental features. Aristotle identified substanceboth primary and secondaryas the most fundamental of the ten categories of being. According to Spinoza, there can be no more than one truly independent being in the universe.

A statement or argument that results from a consistent substitution of constants for variables in a statement form or argument form of the propositional calculus or quantification theory.
What logically or causally secures the occurrence of something else; see necessary / sufficient. Thus, Leibniz supposed that there must always be a sufficient reason for the way things are.
Latin for "of its own kind;" hence, whatever is absolutely unique or distinctive about something.
Latin phrase meaning "highest good." Hence, that which is intrinsically valuable, the ultimate goal or end of human life generally.
Above and beyond the call of duty. Although agents are not obliged by the dictates of ordinary morality to perform supererogatory actsextraordinary feats of heroism or extreme deeds of self-sacrifice, for examplethey may be commended for doing so. Normative theories that demand the performance of the best possible action in every circumstance render supererogation impossible by identifying the permissible with the obligatory.

Belonging to or characteristic of something only in virtue of its having other features. Although a supervenient property cannot be defined in terms of, or reduced to, the properties on which it supervenes, nothing possess (or can possess) those properties without also having it. In this sense, Hare supposed that moral properties are supervenient with respect to straightforward descriptions of human conduct, and Davidson proposes that mental events supervene on physical events.

Not included among the categories of Aristotle and therefore incapable of serving as a categorical term. Hence, any linguistic expression that does not refer to anything else. Thus, "if," "while," and "and," are all syncategorematic terms.
Immediate, intuitive apprehension of the fundamental principles of morality. For such medieval ethicists as Peter Lombard and Aquinas, synderesis, unlike mere conscience, is both infallible and general.

Having exactly the same meaning in more than one use; see homonymous / synonymous / paronymous. Although many since Aristotle have supposed this to be essential for effective communication, Quine has shown that the indeterminacy of translation renders genuine synonymy difficult to secure.
Study of the grammatical relationships among signs, independently of their interpretation or meaning, which is the subject of semantics.
