Foundations of Physics
In this textbook addressed to her son, du Châtelet presents physical principles and defends a metaphysics compatible with experimental science. Space, time, matter and motion are questions for argument rather than a list of results.
Understanding the text
Published anonymously in 1740 and revised in 1742, the book intervenes among Newtonian, Cartesian and Leibnizian traditions. Its use of Leibniz and Wolff is an original contribution rather than mere repetition.
Key points
- 01
Hypotheses
Explanatory hypotheses guide research when they remain answerable to phenomena and open to revision.
- 02
Principles
Sufficient reason expresses a demand for explanation without replacing experimental inquiry.
- 03
Living force
The measurement of motion’s effects was disputed by proponents of mv and mv².
