Earlier Aristotle had objects as primary substances, but later he switched to substantial form [Aristotle, by Lowe]
Things are called 'substances' because they are subjects for everything else [Aristotle]
Substance [ousia] is the subject of predication and cause [aitia?] of something's existence [Aristotle]
Essence (fixed by definition) is also 'ousia', so 'ousia' is both ultimate subject, and a this-thing [Aristotle]
A substance is what-it-is-to-be, or the universal, or the genus, or the subject of saying [Aristotle]
It is matter that turns out to be substance [ousia] [Aristotle]

The substance is the form dwelling in the object [Aristotle]
Substance is unified and universals are diverse, so universals are not substance [Aristotle, by Witt]

In 'Metaphysics' Z substantial primacy (as form) is explanatory rather than ontological [Aristotle, by Wedin]
In 'Metaphysics' substantial forms take over from objects as primary [Aristotle, by Frede,M]
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]
Aristotle's cosmos is ordered by form, and disordered by matter [Aristotle, by Gill,ML]
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]

The 'form' is the recipe for building wholes of a particular kind [Aristotle, by Koslicki]
Things are a unity because there is no clash between potential matter and actual shape/form [Aristotle]
Aristotle's solution to the problem of unity is that form is an active cause or potentiality or nature [Aristotle, by Gill,ML]

We first sense whole entities, and then move to particular parts of it [Aristotle]
There is no whole except for the parts [Aristotle]
A syllable is something different from its component vowels and consonants [Aristotle]

9. Objects / D. Essence of Objects / 4. Essence as Definition
Definitions recognise essences, so are not themselves essences [Aristotle]

Primary substances are ontological in 'Categories', and explanatory in 'Metaphysics' [Aristotle, by Wedin]

9. Objects / D. Essence of Objects / 10. Essence as Species
Generic terms like 'man' are not substances, but qualities, relations, modes or some such thing [Aristotle]
Generalities like man and horse are not substances, but universal composites of account and matter [Aristotle]
Genera are not substances, and do not exist apart from the ingredient species [Aristotle]
'Categories' answers 'what?' with species, genus, differerentia; 'Met.' Z.17 seeks causal essence [Aristotle, by Wedin]
Standardly, Aristotelian essences are taken to be universals of the species [Aristotle, by Witt]
In 'Met.' he says genera can't be substances or qualities, so aren't in the ontology [Aristotle, by Frede,M]
9. Objects / D. Essence of Objects / 11. Essence of Artefacts

Coming to be is by shape-change, addition, subtraction, composition or alteration [Aristotle]
Natural things are their own source of stability through change [Aristotle]
For animate things, only the form, not the matter or properties, must persist through change [Aristotle, by Frede,M]
Change of matter doesn't destroy identity - in Dion and Theon change is a condition of identity [Chrysippus, by Long/Sedley]
9. Objects / E. Objects over Time / 6. Successive Things
A day, or the games, has one thing after another, actually and potentially occurring [Aristotle]
9. Objects / E. Objects over Time / 10. Beginning of an Object
Does the pure 'this' come to be, or the 'this-such', or 'so-great', or 'somewhere'? [Aristotle]
Philosophers have worried about coming-to-be from nothing pre-existing [Aristotle]
The substratum changing to a contrary is the material cause of coming-to-be [Aristotle]
If a perceptible substratum persists, it is 'alteration'; coming-to-be is a complete change [Aristotle]
Coming-to-be may be from nothing in a qualified way, as arising from an absence [Aristotle]
9. Objects / E. Objects over Time / 11. End of an Object
Destruction is dissolution of essence [Aristotle]
9. Objects / E. Objects over Time / 12. Origin as Essential
