Active force is not just potential for action, since it involves a real effort or striving [Leibniz]
|
|
Full Idea:
Active force should not be thought of as the simple and common potential [potentia] or receptivity to action of the schools. Rather, active force involves an effort [conatus] or striving [tendentia] toward action.
|
|
From:
Gottfried Leibniz (On Body and Force, Against the Cartesians [1702], p.252)
|
|
A reaction:
This is why Leibniz is lured into making his active forces more and more animistic, till they end up like proto-minds (though never, remember, conscious and willing minds).

'Partial reference' is when the subject thinks two objects are one object [Field,H, by Recanati]
|
|
Full Idea:
A subject's thought is about A, but, unbeknownst to the subject, B is substituted for A. Then there is Field's 'partial reference', because the subject's thought is still partially about A, even though they are following B.

From:
report of Hartry Field (Theory Change and the Indeterminacy of Reference [1973]) by François Recanati - Mental Files in Flux 2
|
|
A reaction:
Used to interpret a well-known case: Wally says of Udo 'he needs a haircut'; Zach looks at someone else and says 'he sure does'. Recanati explains it by mental files.

Probabilistic causation says C is a cause of E if it increases the chances of E occurring [Mellor, by Tooley]
|
|
Full Idea:
The basic idea of probabilistic causation is that a sufficient condition of C's being a cause of E is that C and E are actual, individual events, and the objective chance of E's occurring is greater given the occurrence of C than it would be without C.
|
|
From:
report of D.H. Mellor (The Facts of Causation [1995]) by Michael Tooley - Causation and Supervenience 5.3
|
|
A reaction:
Mellor has to include objective 'chances' in his ontology to support his theory. As it stands this looks like a weak theory, since the event might not occur despite C happening, and some less likely event might turn out to be the actual cause.

God's laws would be meaningless without internal powers for following them [Leibniz]
|
|
Full Idea:
To say that, in creation, God gave bodies a law for acting means nothing, unless, at the same time, he gave them something by means of which it could happen that the law is followed.
|
|
From:
Gottfried Leibniz (On Body and Force, Against the Cartesians [1702], p.253)
|
|
A reaction:
This is the beginning of the modern rebellion against the medieval view of laws as imposed from outside on passive matter. Unfortunately for Leibniz, once you have postulated active internal powers, the external laws become redundant.

Power is passive force, which is mass, and active force, which is entelechy or form [Leibniz]
|
|
Full Idea:
The dynamicon or power [potentia] in bodies is twofold, passive and active. Passive force [vis] constitutes matter or mass [massa], and active force constitutes entelechy or form.
|
|
From:
Gottfried Leibniz (On Body and Force, Against the Cartesians [1702], p.252)
|
|
A reaction:
This is explicitly equating the innate force understood in physics with Aristotelian form. The passive force is to explain the resistance of bodies. I like the equation of force with power. He says the entelechy is 'analogous' to a soul.
