Single Idea 16727

[catalogued under 7. Existence / C. Structure of Existence / 8. Stuff / b. Mixtures]

Full Idea

The standard view was that in a mixture there is only the mixed body and its substantial form (gold). There are no further substantial forms of the elements, because the elements do not actually exist within the body.

Gist of Idea

In mixtures, the four elements ceased to exist, replaced by a mixed body with a form

A Reaction

This seems to me to be the key idea that was overthrown in the seventeenth century, so that corpuscular matter kept aspects of its ingredients, which science could then investigate. With the substantial form, investigation seemed impossible.
