We get the idea of power by abstracting from ropes, magnets and electric shocks [Priestley]
|
|
Full Idea:
A rope sustains weight, a magnet attracts iron, a charged electrical jar gives a shock, and from these and other similar observations, we get the idea of power, universally and abstractly considered.

From:
Joseph Priestley (Theological and other works [1790], p.191), quoted by Harré,R./Madden,E.H. - Causal Powers 9.II.B
|
|
A reaction:
I agree with this, in that we appear to be observing powers directly, and are not observing something which can then be reduced to non-powers. Nature just can't be a set of inert structures, with forces 'imposed' on them.

The qualities of the world are mere appearances; reality is the motions which cause them [Hobbes]
|
|
Full Idea:
Whatsoever accidents or qualities our senses make us think there be in the world, they are not there, but are seemings and apparitions only. The things that really are in the world without us are those motions by which these seemings are caused.

From:
Thomas Hobbes (The Elements of Law [1640], I.2.10), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 10.2
|
|
A reaction:
This seems to count as a sense-datum theory, rather than a representative theory of perception, since it makes no commitment to the qualities containing any accurate information at all. We just start from the qualities and try to work it out.

Evidence is conception, which is imagination, which proceeds from the senses [Hobbes]
|
|
Full Idea:
All evidence is conception, as it is said, and all conception is imagination and proceeds from sense. And spirits we suppose to be those substances which work not upon the sense, and therefore not conceptible.
|
|
From:
Thomas Hobbes (The Elements of Law [1640], I.11.5), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 16.2
|
|
A reaction:
This is exactly the same as Hume's claim that all ideas are the result of impressions, and is the very essence of empiricism. We see here that such an epistemology can have huge consequences.

Self-preservation is basic, and people judge differently about that, implying ethical relativism [Hobbes, by Tuck]
|
|
Full Idea:
If men are their own judges of what conduces to their preservation, ..all men make different decisions about what counts as a danger, so (for Hobbes) the grimmest version of ethical relativism seems to be the only possible ethical vision.
|
|
From:
report of Thomas Hobbes (The Elements of Law [1640]) by Richard Tuck - Hobbes Ch.2
|
|
A reaction:
This might depend on self-preservation being the only fundamental value. But if self-preservation is not a pressing issue, presumably other values might come into play, some of them less concerned with the individual's own interests.

Attraction or repulsion are not imparted to matter, but actually constitute it [Priestley]
|
|
Full Idea:
Attraction or repulsion appear to me not to be properly what is imparted to matter, but what really makes it what it is, in so much that, without it, it would be nothing at all.
|
|
From:
Joseph Priestley (Theological and other works [1790], p.237), quoted by Harré,R./Madden,E.H. - Causal Powers 9.II.B
|
|
A reaction:
This is music to the ears of anyone who thinks that powers are the fundamentals of nature (like me).

General Relativity allows substantivalism about space-time - that it has independent properties [Hoefer]
|
|
Full Idea:
General Relativity describes space-time in a way that allows it to exist with determinate properties not reducible to the properties and relations of its material contents. Hence nearly all physicists and philosophers writing on GR are substantivalists.
|
|
From:
Carl Hoefer (The Metaphysics of Space-Time Substantivalism [1996], p.5), quoted by Barbara Vetter - Potentiality 7.3
|
|
A reaction:
I'm encouraged by this, as I instinctly favour substantivalism. Imagine removing all the objects from space-time, one by one. What happens as you approach the end of the task? Once they are removed, can they be replaced?
