Propensities are part of a situation, not part of the objects [Popper]
|
|
Full Idea:
Propensities should not be regarded as inherent in an object, such as a die or a penny, but should be regarded as inherent in a situation (of which, of course, the object was part).
|
|
From:
Karl Popper (A World of Propensities [1993], p.14), quoted by George Molnar - Powers 6.2
|
|
A reaction:
Molnar argues against this claim, and I agree with him. We can see why Popper might prefer this relational view, given that powers often only become apparent in unusual relational situations.

Principles of things are not hidden features of forms, but the laws by which they were formed [Newton]
|
|
Full Idea:
The (active) principles I consider not as occult qualities, supposed to result from the specific forms of things, but as general laws of nature, by which the things themselves are formed.
|
|
From:
Isaac Newton (Queries to the 'Opticks' [1721], q 31), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 23.6
|
|
A reaction:
This is the external, 'imposed' view of laws (with the matter passive) at its most persuasive. If laws arise out the stuff (as I prefer to think), what principles went into the formulation of the stuff?
