Russell offered a paraphrase of definite description, to avoid the commitment to objects [Quine]
|
|
Full Idea:
Russell's theory involved defining a term not by presenting a direct equivalent of it, but by 'paraphrasis', providing equivalents of the sentences. In this way, reference to fictitious objects can be simulated without our being committed to the objects.

From:
Willard Quine (Russell's Ontological Development [1966], p.75)
|
|
A reaction:
I hadn't quite grasped that the modern strategy of paraphrase tracks back to Russell - though it now looks obvious, thanks to Quine. Paraphrase is a beautiful way of sidestepping ontological problems. See Frege on the moons of Jupiter.

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).

The pineal gland links soul to body, and unites the two symmetrical sides of the body [Descartes, by PG]
|
|
Full Idea:
The soul is united with the body in just one place, a gland (the pineal) in the centre of the brain. It is placed so that its slightest movement will affect the passions, and it plays the essential role of uniting the two symmetrical sides of the body.
|
|
From:
report of René Descartes (The Passions of the Soul [1649], §31) by PG - Db (ideas)
|
|
A reaction:
See Idea 4862 for Spinoza's nice response to Descartes' proposal. If Descartes had followed brain research for the last four hundred years, at what point would he have wavered? If every single part of the brain seems to 'interact', dualism looks unlikely.

Are there a few primary passions (say, joy, sadness and desire)? [Descartes, by Cottingham]
|
|
Full Idea:
Descartes says there are six primary passions (wonder, love, hatred, desire, joy and sadness); Spinoza says there are just three (joy, sadness and desire).
|
|
From:
report of René Descartes (The Passions of the Soul [1649]) by John Cottingham - The Rationalists p.172
|
|
A reaction:
A dubious project. However, it is now agreed that there are a few (six?) basic universal facial expressions, to which these passions may correspond.

There are six primitive passions: wonder, love, hatred, desire, joy and sadness [Descartes, by Goldie]
|
|
Full Idea:
Descartes said there are six primitive passions, namely wonder, love, hatred, desire, joy and sadness. The others are either species of these, or composed of them.
|
|
From:
report of René Descartes (The Passions of the Soul [1649], 353) by Peter Goldie - The Emotions 4 'Evidence'
|
|
A reaction:
[not sure about ref] It's a nice touch to add 'wonder', which doesn't make it onto anyone else's list.

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.
