Single Idea 13167

[catalogued under 27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces]

Full Idea

Considering 'extended mass' alone was not sufficient to explain the principles of mechanics and the laws of nature, but it is necessary to make use of the notion of 'force', which is very intelligible, despite belonging in the domain of metaphysics.

Gist of Idea

We need the metaphysical notion of force to explain mechanics, and not just extended mass

A Reaction

We may find it surprising that force is a metaphysical concept, but that is worth pondering. It is a mysterious notion within physics. Notice the emphasis on what explains, and what is intelligible. He sees Descartes's system as too passive.
