Aristotelian physics is the form of natural philosophy described in the works of the Greek philosopher Aristotle (384–322 BC). In his work Physics, Aristotle intended to establish general principles of change that govern all natural bodies, both living and inanimate, celestial and terrestrial – including all motion (change with respect to place), quantitative change (change with respect to ...
Aristotelian physics is the form of natural philosophy described in the works of the Greek philosopher Aristotle (384–322 BC). In his work Physics, Aristotle intended to establish general principles of change that govern all natural bodies, both living and inanimate, celestial and terrestrial – including all motion, quantitative change, qualitative change, and substantial change.
Aristotle's principles of being (see section above) influenced Anselm's view of God, whom he called "that than which nothing greater can be conceived." Anselm thought God did not feel emotions such as anger or love but appeared to do so through our imperfect understanding.
Aether naturally moved in circles, and had no contrary, or unnatural, motion. Aristotle also stated that celestial spheres made of aether held the stars and planets. The idea of aethereal spheres moving with natural circular motion led to Aristotle's explanation of the observed orbits of stars and planets in perfectly circular motion. [1] [11]
Aristotle describes two kinds of motion: "violent" or "unnatural ... be little less than a history of European thought". [175] Aristotle has been called the father of ...
This perpetual motion causes "communicated" motion, which is the perceived motion of bodies. [4] Aristotle (384 BC) claimed that all motion is caused, and can be sensed, but originally was potentially present in the now moving body. Once there is motion, that motion will continue infinitely unless it is stopped. [4]
Aristotle defines time as "a number of motion with respect to the before and after" (Phys. 219b1–2), by which he intends to denote motion's susceptibility to division into undetached parts of arbitrary length, a property that it possesses both by virtue of its intrinsic nature and also by virtue of the capacities and activities of percipient ...
Second, if the world changed from a state of rest to a state of motion, the cause of that change to motion would itself have been a motion. He concludes that motion is necessarily eternal. Aristotle argued that a "vacuum" (that is, a place where there is no matter) is impossible. Material objects can come into existence only in place, that is ...
