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.

A machine is best defined by its final cause, which explains the roles of the parts [Leibniz]
|
|
Full Idea:
Any machine ...is best defined in terms of its final cause, so that in the description of the parts it is therefore apparent in what way each of them is coordinated with the others for the intended us.

From:
Gottfried Leibniz (The Human Body is a sort of Machine [1683], p.290), quoted by Richard T.W. Arthur - Leibniz 3 'Machines'
|
|
A reaction:
We would use the 'function', an inherently teleological concept, and a concept which is almost indispensable for giving an illuminating description of the world. If nature is dispositional, it points towards things. Leibniz views persons as machines.
