Mind and Multiple Realizability The claim that mental types are multiply realizable has played an important role in supporting antireductionism in philosophy of mind. The multiple-realizability thesis implies that mental types and physical types are correlated one-many not one-one. A mental state such as pain might be correlated with one type of physical state in a human and another type of physical state in, say,

Scientific Representation To many philosophers, our science is intended to represent reality. For example, some philosophers of science would say Newton’s theory of gravity uses the theoretical terms ‘center of mass’ and ‘gravitational force’ in order to represent how a solar system of planets behaves—the changing positions and velocities of the planets but not their color changes. However, it is very difficult to give a

Compositionality in Language Compositionality is a concept in the philosophy of language. A symbolic system is compositional if the meaning of every complex expression E in that system depends on, and depends only on, (i) E’s syntactic structure and (ii) the meanings of E’s simple parts. If a language is compositional, then the meaning of a sentence S in that language cannot depend directly on

Zeno’s Paradoxes In the fifth century B.C.E., Zeno offered arguments that led to conclusions contradicting what we all know from our physical experience—that runners run, that arrows fly, and that there are many different things in the world. The arguments were paradoxes for the ancient Greek philosophers. Because many of the arguments turn crucially on the notion that space and time are infinitely divisible, Zeno

Cornelius Castoriadis (1922—1997) Cornelius Castoriadis was an important intellectual figure in France for many decades, beginning in the late-1940s. Trained in philosophy, Castoriadis also worked as a practicing economist and psychologist while authoring over twenty major works and numerous articles spanning many traditional philosophical subjects, including politics, economics, psychology, anthropology, and ontology. His oeuvre can be understood broadly as a reflection on the concept of

Consciousness Explaining the nature of consciousness is one of the most important and perplexing areas of philosophy, but the concept is notoriously ambiguous. The abstract noun “consciousness” is not frequently used by itself in the contemporary literature, but is originally derived from the Latin con (with) and scire (to know). Perhaps the most commonly used contemporary notion of a conscious mental state is captured by
