accident (n.) late 14c., "an occurrence, incident, event," from Old French accident (12c.), from Latin accidentem (nominative accidens), present participle of accidere "happen, fall out, fall upon," from ad- "to" (see ad-) + cadere "fall" (see case (n.1)). Meaning grew from "something that happens, an event," to "something that happens by chance," then "mishap." Philosophical sense "non-essential characteristic of a thing" is late 14c. Meaning "unplanned child" is attested by 1932. ---------------- from the book 'Dictionary of Islamic Philosophical Terms' ‘ard (pl. a‘rad) Accident. As one of the predicables (al-alfaz al-khamasa) ‘ard is that quality which adhere to a subject (maudu, q.v.), but–opposed to property –it neither constitutes its essense, nor does it necessarily flow form it, e.g. the color of man. According to the Peripatetics (al-Mashsha’un, q.v.), accidents may change, disappear, or be added, while substances (jauhar, q.v.) remains the same. Accident, thus, has no independent existence, but exists only in another being, a substance or another accident. According to the Mutakallimun, more particularly the Ash‘arites, however, an accident cannot exist in another accident but only in a substance. But no substance can ever exist apart form its qualities or accidents. Hence, the substance being inseparable from its accidents, like the latter, is also merely transitory, i.e. has only a momentary existence. Everything that exists, thus, consists of mere transitory units (atoms) having only a moment’s duration and needs must, therefore, be perpetually re-created by the will of God. See also alfasl al-khass and al-fasl al-‘amm. jauhar Lit. "jewel"; technically substance, one of the fundamental terms with the philosophers: the first of the ten Aristotelian categories (al-maqulat al-‘ashr, q.v.). As a general term jauhar signifies everything that exists in reality, all bodies and parts of bodies, the sky and the stars and the earth, water and fire and air, plants and animals, in short all things in the visible world. According to the Mutakallimun, particularly the Ash‘arites, jauhar is merely a bearer of accidents, and as a substratum of accidents it is constituted of atoms which by their aggregate compose the body. hadith or haadith Temporal, originated. al-ab‘ad al-thalathah The three dimensions of a material body: length, width, and depth. These dimensions do not enter into the definition of a thing; they are just some of its accidents and not part of its existence, even though they determine its state. ----------------- it's obvious that in TKM the word 'accident' has been used in the sense of 'an event' i.e something that came into existence without having existed prior to this i.e a created thing. ----------------- A link to this book was posted by Hamoudeh of marifah forum.
