Single Idea 11833

[filed under theme 9. Objects / B. Unity of Objects / 2. Substance / e. Substance critique ]

Full Idea

It has long since been noticed that in all substances the subject proper, namely what is left over after all the accidents (as predicates) have been taken away and hence the 'substantial' itself, is unknown to us.

Gist of Idea

The substance, once the predicates are removed, remains unknown to us

Source

Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 333)

A Reaction

This is the terminus of the process of abstraction (though Wiggins says such removal of predicates is a myth). Kant is facing the problem of the bare substratum, or haecceity.

The only meaning we have for substance is a collection of qualities [Hume]
Aristotelians propose accidents supported by substance, but they don't understand either of them [Hume]
The substance, once the predicates are removed, remains unknown to us [Kant]
'Substance' is just a word for groupings and structures in experience [James]
An object produces the same percepts with or without a substance, so that is irrelevant to science [Russell]
We need not deny substance, but there seems no reason to assert it [Russell]
The assumption by physicists of permanent substance is not metaphysically legitimate [Russell]
We can escape substance and its properties, if we take fields of pure powers as ultimate [Harré/Madden]
Rather than 'substance' I use 'objects', which have properties [Heil]
Empiricists gave up 'substance', as unknowable substratum, or reducible to a bundle [Oderberg]
A phenomenalist cannot distinguish substance from attribute, so must accept the bundle view [Macdonald,C]
When we ascribe a property to a substance, the bundle theory will make that a tautology [Macdonald,C]
Substances persist through change, but the bundle theory says they can't [Macdonald,C]
A substance might be a sequence of bundles, rather than a single bundle [Macdonald,C]
For corpuscularians, a substance is just its integral parts [Pasnau]
