Single Idea 3911

[from 'Modern Philosophy:introduction and survey' by Roger Scruton, in 17. Mind and Body / A. Mind-Body Dualism / 2. Interactionism ]

Full Idea

It is often held to be a consequence of the rationalist conception of substance, that separate substances cannot interact (since causal interaction is a form of mutual dependence).

Clarification

'Substances' are thought of as the underlying basis of existence and identity

Gist of Idea

The very concept of a substance denies the possibility of mutual interaction and dependence

A Reaction

Yes, substances seem incapable of interaction, just as Leibniz argues that perfections could never interact. They are too pure.
