Single Idea 5466

[filed under theme 12. Knowledge Sources / B. Perception / 2. Qualities in Perception / c. Primary qualities ]

Full Idea

For Boyle, Locke and Newton, the qualities inherent in bodies were just the primary qualities, namely number, figure, size, texture, motion and configuration of parts, impenetrability and, perhaps, body (or mass).

Gist of Idea

Primary qualities are number, figure, size, texture, motion, configuration, impenetrability and (?) mass

A Reaction

It is nice to have a list. Ellis goes on to say these are too passive, and urges dispositions as primary. Even so, the original seventeenth century insight seems to me a brilliant step forward in our understanding of the world.
