The concept of mind excludes body, and vice versa [Descartes]
|
|
Full Idea:
The concept of body includes nothing at all which belongs to the mind, and the concept of mind includes nothing at all which belongs to the body.
|
|
From:
René Descartes (Reply to Fourth Objections [1641], 225)
|
|
A reaction:
A headache? Hunger? The mistake, I think, is to regard the mind as entirely conscious, thus creating a sharp boundary between two aspects of our lives. As shown by blindsight, I take many of my central mental operations to be pre- or non-conscious.

The attribution of necessity to causation is either primitive animism, or confusion with logical necessity [Ayer]
|
|
Full Idea:
How are we to explain the word 'must' [about causation]? The answer is, I think, that it is either a relic of animism, or else reveals an inclination to treat causal connexion as if it were a form of logical necessity.

|
From:
A.J. Ayer (The Foundations of Empirical Knowledge [1940], IV.18)
|
|
A reaction:
The animism proposal just about makes sense (as a primitive feature of minds), but why would anyone, if they had the time and understanding, dream of treating a regular connection as a 'logical' necessity?
