| 15779 | Possibility is when the necessity of the contrary is false [Aristotle] |
| Full Idea: The potential occurs when it is not necessary that its contrary be false. For example, it is potential that a man should be seated, since it is not false of necessity that he is not seated. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1019b26) | |
| A reaction: This is the standard point in modal logic that possibly is equivalent to not-necessarily-not (◊p → ¬□¬p). |
| 22518 | The actual must be possible, because it occurred [Aristotle] |
| Full Idea: Actual events are evidently possible, otherwise they would not have occurred. | |
| From: Aristotle (The Poetics [c.347 BCE], 1451b18) | |
| A reaction: [quoted online by Peter Adamson] Seems like common sense, but it's important to have Aristotle assert it. |
| 15769 | Anything which is possible either exists or will come into existence [Aristotle] |
| Full Idea: If what we have stated either is the possible or something connected to it, there can of course be no question of its being true to say that x is capable of being but will not be. ...What is not but is capable of being either is or comes into being. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1047b05) | |
| A reaction: I'm a bit startled to find the great Aristotle spouting this nonsense. It's possible that every bird in England could simultaneously land in my home town, but it ain't never going to happen. Modern women could bear 50 children, but won't. |
| 15777 | A 'potentiality' is a principle of change or process in a thing [Aristotle] |
| Full Idea: What is a principle of change or process is said to be a 'potentiality' [dunamis], whether in something else or in the thing itself qua something else. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1019a18) |
| 11254 | Matter is potentiality [Aristotle, by Politis] |
| Full Idea: Aristotle conceives of matter (hulé) as potentiality. ...He has a process-based notion of matter. ...It is something which has the power ('dunamis') to generate a thing. | |
| From: report of Aristotle (Physics [c.337 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 2.4 | |
| A reaction: Politis says that 'dunamis' is usually translated as 'potentiality', but he prefers to translate it as 'power'. I take this to be highly significant in connecting Aristotle to modern scientific essentialism. |
| 14544 | Potentialities are always for action, but are conditional on circumstances [Aristotle] |
| Full Idea: The possession of a potentiality just is the possession of a potentiality to act, and such a potentiality is not unconditional but depends on the obtaining of propitious circumstances, which includes the satisfaction of a ceteris paribus condition. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1048a18) | |
| A reaction: This seems to be pretty exactly what we mean by a 'power', as something which requires no other driving force, but which only expresses itself with the endless complexity of the rest of nature. |
| 15774 | We recognise potentiality from actuality [Aristotle] |
| Full Idea: It is from the actuality that the potentiality is recognised. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1051a29) | |
| A reaction: I presume it is from this simple fact that Sider and others draw the mistaken inference that there are no potentialities in the actual world. |
| 15778 | Things are destroyed not by their powers, but by their lack of them [Aristotle] |
| Full Idea: Things are broken, compressed, bent and, in a word, destroyed not by dint of having a potentiality but by dint of not having one and by missing out on something. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1019a27) | |
| A reaction: Presumably an ontology entirely based on powers would not also need to catalogue absence of powers. The positive ones do the job. No power, no destruction. |
| 13110 | Intrinsic cause is prior to coincidence, so nature and intelligence are primary causes, chance secondary [Aristotle] |
| Full Idea: A cause in its own right is prior to a coincidental cause. So spontaneity and chance are posterior to intelligence and nature. Hence however much spontaneity is the cause of the universe, intelligence and nature are more primary causes. | |
| From: Aristotle (Physics [c.337 BCE], 198a10) | |
| A reaction: This seems to be Aristotle's final word on chance - that it is a genuine sort of causation, but only a secondary one. I take 'nature' to refer to the powers of essences. Aristotle does not accept meetings in the market as uncaused events. |
| 13108 | Chance is a coincidental cause among events involving purpose and choice [Aristotle] |
| Full Idea: Clearly chance is a coincidental cause in the sphere of events which have some purpose and are the subject of choice. | |
| From: Aristotle (Physics [c.337 BCE], 197a05) | |
| A reaction: This is the culmination of his discussion of going to the market place and happening to meet your debtor (196b33). We must now decide whether a 'coincidental cause' is a true case of causation. |
| 13106 | Maybe there is no pure chance; a man's choices cause his chance meetings [Aristotle] |
| Full Idea: Some people find there is no such thing as a chance event. ..If someone chanced to come into the city square and met someone he wanted to meet but had not expected, they say the cause was his wanting to go and do business in the square. | |
| From: Aristotle (Physics [c.337 BCE], 195b39) | |
| A reaction: Aristotle spends the book discussing the problem. There is a clear candidate for an uncaused event here, in the chance meeting of two people. See Idea 13108. |
