9. Objects / D. Essence of Objects / 8. Essence as Explanatory
The four explanations are the main aspects of a thing's nature [Aristotle, by Moravcsik]
     Full Idea: Aristotle sees as the main types of aitia (explanation) those that are also to be construed as the main aspects of the physis (nature) of anything.
     From: report of Aristotle (Physics [c.337 BCE]) by Julius Moravcsik - Aristotle on Adequate Explanations 1
     A reaction: Interestingly, this suggests that having rejected the Four Causes in favour of the Four Explanations, we might even consider them as the Four Natures, which ties explanation very closely to essence.
A thing's nature is what causes its changes and stability [Aristotle]
     Full Idea: The nature of a thing is a certain principle and cause of change and stability in the thing.
     From: Aristotle (Physics [c.337 BCE], 192b20)
     A reaction: A helpful contribution to the discussion, as most thinkers just boggle when asked to specify the core of something's identity. Aristotle's proposal links identity to causation, which is very appealing to a physical account of all of reality. Cf 5086.
