Dimension-by-Dimension Evidence

What each work's passages reveal about its stance on each of the six dimensions.

Time

Discourse on the Method

The temporal structure of the Discourse is autobiographical: the years of doubt giving way to the foundational discovery. Time itself is Newtonian-substantival background.

Space

Discourse on the Method

Cartesian res extensa — extension as the essence of body. The Discourse's Part V develops the mechanist analysis of extended substance.

Matter

Discourse on the Method

The animal as machine; the physical world as extended substance in motion, governed by mechanical laws.

Observer

Discourse on the Method

The thinking subject as the bedrock — the first genuinely first-personal philosophical observer. Disembodied in essence, though enwombed in a body; God as personal-providential framework.

Energy

Discourse on the Method

Implicit: motion in the extended world is the continuation of God's creative act. Not thematised in the Discourse.

Information

Discourse on the Method

Clear and distinct ideas as the preserved information of rational knowledge; the cogito as the founding personal information.

Internal Tensions

Where each work's argument pulls against itself.

Discourse on the Method

The Discourse's status as founding charter of modern subjectivity has been simultaneously celebrated (by rationalists and analytic philosophers) and criticised (by Heidegger, Levinas, Foucault, feminist critics, embodied-cognition theorists) for separating the thinking self from its embodied, social, historical situation. The relation between the Discourse and the more rigorous Meditations (1641) is itself an interpretive question — the Meditations sometimes read as a corrective to the Discourse's more ambitious claims. Descartes's mechanist treatment of animals in Part V has been increasingly criticised as morally and biologically inadequate.
