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).

If a blind persons suddenly sees a kestrel, that doesn't make visual and theoretical kestrels different [Papineau on Jackson]
|
|
Full Idea:
An ornithological Mary might know everything theoretical about kestrels, but be blind from birth, then have her sight restored. She now knows "That bird eats mice", so visual kestrels must be ontologically distinct from theoretical ones.

From:
comment on Frank Jackson (Epiphenomenal Qualia [1982]) by David Papineau - Thinking about Consciousness 6.3
|
|
A reaction:
A nice reductio, and I think this pinpoints best what is wrong with the knowledge argument. Knowledge, and the means of acquiring it, are two distinct things. When I see x, I don't acquire knowledge of x, AND knowledge of my seeing x.

Mary learns when she sees colour, so her complete physical information had missed something [Jackson]
|
|
Full Idea:
It seems obvious that Mary will learn something about the world when she is released from her black-and-white room; but then it is inescapable that her previous knowledge was incomplete; she had all the physical information, so there is more to have.
|
|
From:
Frank Jackson (Epiphenomenal Qualia [1982], §1)
|
|
A reaction:
This is Jackson's famous 'knowledge argument', which seems to me misconceived. Since I don't think phenomenal colours are properties of objects (Idea 5456), Mary learns more about herself, and about her means of acquiring knowledge.

The good life aims at perfections, or absolute laws, or what is absolutely desirable [Green,TH]
|
|
Full Idea:
The differentia of the good life …is controlled by the consciousness of there being some perfection which has to be fulfilled, some law which has to be obeyed, something absolutely desirable whatever the individual may for the time desire.
|
|
From:
T.H. Green (Prolegomena to Ethics [1882], p.134), quoted by John H. Muirhead - The Service of the State II
|
|
A reaction:
The 'perfection' suggests Plato, and the 'law' suggests Kant. The idea that something is 'absolutely desirable' is, I suspect, aimed at the utilitarians, who don't care what is desired. I'm no idealist, but have some sympathy with this idea.

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.
