Plato's Parmenides has a three-part theory, of Primal One, a One-Many, and a One-and-Many [Plato, by Plotinus]
|
|
Full Idea:
The Platonic Parmenides is more exact [than Parmenides himself]; the distinction is made between the Primal One, a strictly pure Unity, and a secondary One which is a One-Many, and a third which is a One-and-Many.
|
|
From:
report of Plato (Parmenides [c.364 BCE]) by Plotinus - The Enneads 5.1.08
|
|
A reaction:
Plotinus approves of this three-part theory. Parmenides has the problem that the highest Being contains no movement. By placing the One outside Being you can give it powers which an existent thing cannot have. Cf the concept of God.

Change is the implied actuality of that which exists potentially [Aristotle]
|
|
Full Idea:
Change is the actuality of that which exists potentially, in so far as it is potentially this actuality. Thus, the actuality of a thing's capacity for alteration, in so far as it is a capacity for alteration, is alteration.
|
|
From:
Aristotle (Physics [c.337 BCE], 201a10)
|
|
A reaction:
Not very informative, until you add Idea 16114, telling us that potentiality is best seen as 'power'. Then we have 'all change is the active expression of powers', which strikes me as rather interesting.

Aristotle's formal and material 'becauses' [aitiai] arguably involve grounding [Aristotle, by Correia/Schnieder]
|
|
Full Idea:
Aristotle's distinction between four different kinds of aitia ('becauses'?) arguably involves the recognition of grounding in the formal and material aitia.
|
|
From:
report of Aristotle (Physics [c.337 BCE], 198a24) by Correia,F/Schnieder,B - Grounding: an opinionated introduction 2
|
|
A reaction:
Insofar as the other two (efficient and final) involve explanation, one might say that they too involve a different sort of grounding. Is a statue 'grounded' in the sculptor, or in the purpose of the statue?
