Full Idea

Aristotle's mature ontology takes biological organisms as its paradigm substances.

Gist of Idea

Mature Aristotle sees organisms as the paradigm substances

Source

report of Aristotle (Metaphysics [c.324 BCE]) by Robert Pasnau - Metaphysical Themes 1274-1671 26.1

A Reaction

'Mature' is here to eliminate 'Categories' where, I take it, any coherent object counts as a substance, with the categories giving the essence. Organism are more clearly categorised, but that's all. Van Inwagen makes this idea a key one.

Generalities like man and horse are not substances, but universal composites of account and matter [Aristotle]

An actuality is usually thought to be a process [Aristotle]
Anything which is possible either exists or will come into existence [Aristotle]

Essences are not properties (since those can't cause individual substances) [Aristotle, by Witt]
Plato says changing things have no essence; Aristotle disagrees [Aristotle, by Politis]
Essential form is neither accidental nor necessary to matter, so it appears not to be a property [Aristotle, by Witt]
The traditional view of Aristotle is God (actual form) at top and prime matter (potential matter) at bottom [Aristotle, by Gill,ML]
God is not a creator (involving time and change) and is not concerned with the inferior universe [Aristotle, by Armstrong,K]
For Aristotle God is defined in an axiom, for which there is no proof [Aristotle, by Frede,M]
Aristotle's cosmos is ordered by form, and disordered by matter [Aristotle, by Gill,ML]
Aristotle's solution to the problem of unity is that form is an active cause or potentiality or nature [Aristotle, by Gill,ML]
Aristotle's form improves on being non-predicable as a way to identify a 'this' [Aristotle, by Wiggins]
Aristotle's essence explains the existence of an individual substance, not its properties [Aristotle, by Witt]

Aristotle's conception of matter applies to non-physical objects as well as physical objects [Aristotle, by Fine,K]

Aristotle may only have believed in prime matter because his elements were immutable [Aristotle, by Alexander,P]
Aristotle says matter is a lesser substance, rather than wholly denying that it is a substance [Aristotle, by Kung]
Aristotle moved from realism to nominalism about substances [Aristotle, by Frede,M]
A substance is a proper subject because the matter is a property of the form, not vice versa [Aristotle, by Gill,ML]
'Ousia' is 'primary being' not 'primary substance' [Aristotle, by Politis]
Substance is prior in being separate, in definition, and in knowledge [Aristotle, by Witt]
In Aristotle, 'proté ousia' is 'primary being', and 'to hupokeimenon' is 'that which lies under' (or 'substance') [Aristotle, by Politis]
Substance is distinct being because of its unity [Aristotle, by Witt]
Primary being ('proté ousia') exists in virtue of itself, not in relation to other things [Aristotle, by Politis]
Non-primary beings lack essence, or only have a derived essence [Aristotle, by Politis]

Form and matter may not make up a concrete particular, because there are also accidents like weight [Aristotle, by Frede,M]
Aristotle claims that the individual is epistemologically prior to the universal [Aristotle, by Witt]
Aristotle takes essence and form as a particular, not (as some claim) as a universal, the species [Aristotle, by Politis]
If definition is of universals, many individuals have no definition, and hence no essence [Aristotle, by Witt]
Actual knowledge is of the individual, and potential knowledge of the universal [Aristotle, by Witt]
The Aristotelian view is that the essential properties are those that sort an object [Aristotle, by Marcus (Barcan)]
Aristotle doesn't think essential properties are those which must belong to a thing [Aristotle, by Kung]
For Aristotle, there are only as many properties as actually exist [Aristotle, by Jacquette]
Properties are just the ways in which forms are realised at various times [Aristotle, by Frede,M]
The 'propriae' or 'necessary accidents' of a thing are separate, and derived from the essence [Aristotle, by Koslicki]
Essential properties explain in conjunction with properties shared by the same kind [Aristotle, by Kung]
It is wrong to translate 'ousia' as 'substance' [Aristotle, by Politis]
Active 'dunamis' is best translated as 'power' or 'ability' (rather than 'potentiality') [Aristotle, by Gill,ML]
