The most primitive thing in substances is force, which leads to their actions and dispositions [Leibniz]
|
|
Full Idea:
Since everything that one conceives in substances reduces to their actions and passions and to the dispositions that they have for this effect, I don't see how one can find there anything more primitive than the principle of all of this, which is force.

From:
Gottfried Leibniz (Letters to Jacques Lenfant [1693], 1693.11.25), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 4

A reaction:
This is an attempt to connect Aristotelian essentialism with the notion of force in the new physics, and strikes me as an improvement on the original, and as good a basis for metaphysics as any I have heard of.

Strong foundationalism needs strict inferences; weak version has induction, explanation, probability [Kvanvig]
|
|
Full Idea:
Strong foundationalists require truth-preserving inferential links between the foundations and what the foundations support, while weaker versions allow weaker connections, such as inductive support, or best explanation, or probabilistic support.

From:
Jonathan Kvanvig (Epistemic Justification [2011], II)

A reaction:
[He cites Alston 1989] Personally I'm a coherentist about justification, but I'm a fan of best explanation, so I'd vote for that. It's just that best explanation is not a very foundationalist sort of concept. Actually, the strong version is absurd.
