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.

If two people can have phenomenally identical experiences, they can't involve the self [Brogaard]
|
|
Full Idea:
It is plausible that you and I can have perceptual experiences with the same phenomenology of two trees at different distances from us (perhaps at different times). ..So our perceptual experiences cannot contain you or me in the content of representation.

From:
Berit Brogaard (Perceptual Content and Monadic Truth [2009], p.223), quoted by Cappelen,H/Dever,Josh - The Inessential Indexical 08.2
|
|
A reaction:
If you accept the example, which seems reasonable, then that pretty conclusively shows that perception is not inherently indexical.
