Modern empirical metaphysics focuses on ontological commitments of discourse, or on presuppositions [Loux/Zimmerman]
|
|
Full Idea:
The empiricist revival of metaphysics came with Quine, who focused on ontological commitments associated with accepting a body of discourse, and Strawson, asking about the presuppositions of our conceptual practices.

From:
M Loux / D Zimmerman (Intro to Oxford Hndbk of Metaphysics [2003])
|
|
A reaction:
I find myself preferring the British approach. I can discourse about things without ontological commitment, and utter truths about non-existent things. I really yearn, though, for the third way - actually reasoning towards knowing what's out there.

The question is whether force is self-sufficient in bodies, and essential, or dependent on something [Lenfant]
|
|
Full Idea:
The whole question is to know if the force to act in bodies is in matter something distinct and independent of everything else that one conceives there. Without that, this force cannot be its essence, and will remain the result of some primitive quality.
|
|
From:
Jacques Lenfant (Letters to Leibniz [1693], 1693.11.07), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 8
|
|
A reaction:
This challenge to Leibniz highlights the drama of trying to simultaneously arrive at explanations of things, and to decide the nature of essence. Leibniz replied that force is primitive, because it is the 'principle' of behaviour and dispositions.

The peripatetics treated forms and real qualities as independent of matter, and non-material [Alexander,P]
|
|
Full Idea:
The peripatetic philosophers, in spite of their disagreements, all treated forms and real qualities as independent of matter and not to be understood in material terms.
|
|
From:
Peter Alexander (Ideas, Qualities and Corpuscles [1985], 54)
|
|
A reaction:
This is the simple reason why hylomorphism became totally discredited, in the face of the 'mechanical philosophy'. But there must be a physical version of hylomorphism, and I don't think Aristotle himself would reject it.

Can the qualities of a body be split into two groups, where the smaller explains the larger? [Alexander,P]
|
|
Full Idea:
Is there any way of separating the qualities that bodies appear to have into two groups, one as small as possible and the other as large as possible, such that the smaller group can plausibly be used to explain the larger?
|
|
From:
Peter Alexander (Ideas, Qualities and Corpuscles [1985], 5.02)
|
|
A reaction:
Alexander implies that this is a question Locke asked himself. This is pretty close to what I take to be the main question for essentialism, though I am cautious about couching it in terms of groups of qualities. I think this was Aristotle's question.

Science has been partly motivated by the belief that the universe is run by God's laws [Alexander,P]
|
|
Full Idea:
The idea of a designed universe has not been utterly irrelevant to the scientific project; it is one of the beliefs that can give a scientist the faith that there are laws, waiting to be discovered, that govern all phenomena.
|
|
From:
Peter Alexander (Ideas, Qualities and Corpuscles [1985], 03.3)
|
|
A reaction:
Of course if you start out looking for the 'laws of God' that is probably what you will discover. Natural selection strikes me as significant, because it shows no sign of being a procedure appropriate to a benevolent god.
