In Philosophy
Further information: Ontology and MetaphysicsA physical body is an enduring object that exists throughout a particular trajectory of space and orientation over a particular duration of time, and which is extended in the world of physical space, e.g. as studied by physics. This contrasts with abstract objects such as mathematical objects which do not exist at any particular time or place. Examples are a cloud, a human body, a weight, a billard ball, a table, or a proton. This is contrasted with abstract objects such as mental objects, which exist in the mental world, and mathematical objects. Other examples that are not physical bodies are emotions, the concept of "justice", a feeling of hatred, or the number "3". In some philosophies, like the Idealism of George Berkeley, a physical body is a mental object, but still has extension in the space of a visual field.

Famous quotes containing the word philosophy:
“The Greeks, with their truly healthy culture, have once and for all justified philosophy simply by having engaged in it, and having engaged in it more fully than any other people.”
—Friedrich Nietzsche (1844–1900)
“The very hope of experimental philosophy, its expectation of constructing the sciences into a true philosophy of nature, is based on induction, or, if you please, the a priori presumption, that physical causation is universal; that the constitution of nature is written in its actual manifestations, and needs only to be deciphered by experimental and inductive research; that it is not a latent invisible writing, to be brought out by the magic of mental anticipation or metaphysical mediation.”
—Chauncey Wright (1830–1875)
