| Existence In common usage, existence is the world of which we are aware through our senses, but in philosophy the word has a more specialized meaning, and is often contrasted with essence. Philosophers investigate questions such as "What exists?" "How do we know?" "To what extent are the senses a reliable guide to existence?" "What is the meaning, if any, of assertions of the existence of categories, ideas, and abstractions." Existence

| Epiphenomenalism In philosophy of mind, epiphenomenalism, also known as 'Type-E Dualism' is a view according to which some or all mental states are mere epiphenomena (side-effects or by-products) of physical states of the world. Thus, epiphenomenalism denies that the mind (as in its states, not its processing) has any influence on the body or any other part of the physical worldall mental states are inert, while others claim that only some mental states are inert.

| Edmund Husserl Edmund Gustav Albrecht Husserl (; April 8, 1859, Prostějov, Moravia, Austrian Empire – April 26, 1938, Freiburg, Germany) was a philosopher who is deemed the founder of phenomenology. He broke with the positivist orientation of the science and philosophy of his day, believing that experience is the source of all knowledge, while at the same time he elaborated critiques of psychologism and historicism.

| Euthanasia Euthanasia (from the Greek ευθανασία meaning "well death"ευ-, eu- (well or good) + θάνατος, thanatos (death)) refers to the practice of ending a life in a painless manner. Many different forms of euthanasia can be distinguished, including animal euthanasia and human euthanasia, and within the latter, voluntary and involuntary euthanasia. Voluntary euthanasia and physician-assisted suicide have been the focus of great controversy in recent years. Euthanasia

| Evolutionarily stable strategy In game theory and behavioural ecology, an evolutionarily stable strategy (ESS) is a strategy which, if adopted by a population of players, cannot be invaded by any alternative strategy that is initially rare. An ESS is an equilibrium refinement of the Nash equilibrium -- it is a Nash equilibrium which is "evolutionarily" stable meaning that once it is fixed in a population, natural selection alone is sufficient to prevent alternative (mutant) strategies from successfully invading.

| Earthquake An earthquake (also known as a tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Earthquakes are recorded with a seismometer, also known as a seismograph. The moment magnitude of an earthquake is conventionally reported, or the related and mostly obsolete Richter magnitude, with magnitude 3 or lower earthquakes being mostly imperceptible and magnitude 7 causing serious damage over large areas.

| Egalitarianism Egalitarianism (derived from the French word égal, meaning equal) or Equalism is a political doctrine that holds that all people should be treated as equals and have the same political, economic, social, and civil rights.

In actual practice, one may be considered an egalitarian in most areas listed below, even if not subscribing to equality in every possible area of individual difference. Egalitarianism

| ELIZA ELIZA was a computer program and an early example (by modern standards) of primitive natural language processing. ELIZA operated by processing users' responses to scripts, the most famous of which was DOCTOR, a simulation of a Rogerian psychotherapist. In this mode, ELIZA mostly rephrased the user's statements as questions and posed those to the 'patient.' ELIZA was written by Joseph Weizenbaum between 1964 to 1966. ELIZA

| EPR paradox In quantum mechanics, the EPR paradox (or Einstein–Podolsky–Rosen paradox) is a thought experiment which challenged long-held ideas about the relation between the observed values of physical quantities and the values that can be accounted for by a physical theory. "EPR" stands for Einstein, Podolsky, and Rosen, who introduced the thought experiment in a 1935 paper to argue that quantum mechanics is not a complete physical theory. EPR_paradox

| Emotion An emotion is a mental and physiological state associated with a wide variety of feelings, thoughts, and behavior. Emotions are subjective experiences, or experienced from an individual point of view. Emotion is often associated with mood, temperament, personality, and disposition. The English word 'emotion' is derived from the French word émouvoir. This is based on the Latin emovere, where e- (variant of ex-) means 'out' and movere means 'move'. The related term "motivation" is also derived from movere. Emotion

| Force See also Force (disambiguation).In physics, a force is a push or pull that can cause an object with mass to change its velocity. Force has both magnitude and direction, making it a vector quantity. Newton's second law states that an object with a constant mass will accelerate in proportion to the net force acting upon and in inverse proportion to its mass. Equivalently, the net force on an object equals the rate at which its momentum changes. See also thrust. Force
