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.
The intellect, nous, "or whatever else it be that is thought to rule and lead us by nature, and to have cognizance of what is noble and divine" is the highest activity, according to Aristotle (contemplation or speculative thinking, theōríā).
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]
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]
(As emphasized by Aristotle, this requires his distinction between accidental causes and natural causes.) [8] According to Aristotle, when we refer to the nature of a thing, we are referring to the form or shape of a thing, which was already present as a potential, an innate tendency to change, in that material before it achieved that form ...
Aristotle defines the agent or efficient "cause" (κινοῦν, kinoûn) [16] of an object as that which causes change and drives transient motion (such as a painter painting a house) (see Aristotle, Physics II 3, 194b29). In many cases, this is simply the thing that brings something about.
The fact that it cannot easily be classified may indeed be one of the reasons why Aristotle usually leaves it out of his standard list of change.” Frede 290 [1] “Aristotle first of all shows that mixture must be a process sui generis and not identical with generation and corruption, nor with any of the other kinds of change that he had ...
