Metaphysics aims at the essence of things, and a system to show how this explains other truths [Richardson]
|
|
Full Idea:
The core of metaphysics is an account of the 'essence' or 'being' of things. ...And metaphysics needs system, to show how these primary truths reach out into all the other truths, to help us see that, and how, they are true.
|
|
From:
John Richardson (Nietzsche's System [2002], Intro)
|
|
A reaction:
I like the phrase 'the essential nature' of things, because it doesn't invoke rather dodgy entities called 'essences', but everyone understands the idea of focusing on what is essential, and on things having a distinct 'nature'.

Metaphysics needs systems, because analysis just obsesses over details [Richardson]
|
|
Full Idea:
Metaphysics makes system a virtue, contrary to the tendency of analysis, which breaks a problem into ever finer parts and then absorbs itself in these.
|
|
From:
John Richardson (Nietzsche's System [2002], Intro)
|
|
A reaction:
I disagree, because it seems to rule out analytic metaphysics. I prefer Bertrand Russell's view. Admittedly analysis oftens gets stuck in the bog, especially if it hopes for salvation in logic, only to discover its certainties endlessly receding.

Substitutional existential quantifier may explain the existence of linguistic entities [Parsons,C]
|
|
Full Idea:
I argue (against Quine) that the existential quantifier substitutionally interpreted has a genuine claim to express a concept of existence, which may give the best account of linguistic abstract entities such as propositions, attributes, and classes.
|
|
From:
Charles Parsons (A Plea for Substitutional Quantification [1971], p.156)
|
|
A reaction:
Intuitively I have my doubts about this, since the whole thing sounds like a verbal and conventional game, rather than anything with a proper ontology. Ruth Marcus and Quine disagree over this one.

Parsons says counting is tagging as first, second, third..., and converting the last to a cardinal [Parsons,C, by Heck]
|
|
Full Idea:
In Parsons's demonstrative model of counting, '1' means the first, and counting says 'the first, the second, the third', where one is supposed to 'tag' each object exactly once, and report how many by converting the last ordinal into a cardinal.
|
|
From:
report of Charles Parsons (Frege's Theory of Numbers [1965]) by Richard G. Heck - Cardinality, Counting and Equinumerosity 3
|
|
A reaction:
This sounds good. Counting seems to rely on that fact that numbers can be both ordinals and cardinals. You don't 'convert' at the end, though, because all the way you mean 'this cardinality in this order'.

If a mathematical structure is rejected from a physical theory, it retains its mathematical status [Parsons,C]
|
|
Full Idea:
If experience shows that some aspect of the physical world fails to instantiate a certain mathematical structure, one will modify the theory by sustituting a different structure, while the original structure doesn't lose its status as part of mathematics.
|
|
From:
Charles Parsons (Review of Tait 'Provenance of Pure Reason' [2009], §2)
|
|
A reaction:
This seems to be a beautifully simple and powerful objection to the Quinean idea that mathematics somehow only gets its authority from physics. It looked like a daft view to begin with, of course.

The 'will' doesn't exist; there is just conclusion, then action [Homer, by Williams,B]
|
|
Full Idea:
Homer left out another mental action lying between coming to a conclusion and acting on it; and he did well, since there is no such action, and the idea is the invention of bad philosophy.
|
|
From:
report of Homer (The Iliad [c.850 BCE]) by Bernard Williams - Shame and Necessity II - p.37
|
|
A reaction:
This is a characteristically empiricist view, which is found in Hobbes. The 'will' seems to have a useful role in folk psychology. We can at least say that coming to a conclusion that I should act, and then actually acting, are not the same thing.

Plato says the Good produces the Intellectual-Principle, which in turn produces the Soul [Homer, by Plotinus]
|
|
Full Idea:
In Plato the order of generation is from the Good, the Intellectual-Principle; from the Intellectual-Principle, the Soul.
|
|
From:
report of Homer (The Iliad [c.850 BCE], 509b) by Plotinus - The Enneads 5.1.08
|
|
A reaction:
The doctrine of Plotinus merely echoes Plato, in that case, except that the One replaces the Form of the Good. Does this mean that what is first in Plotinus is less morally significant, and more concerned with reason and being?

Humans dominate because, unlike other animals, they have a synthesis of conflicting drives [Richardson]
|
|
Full Idea:
In contrast to the other animals, man has cultivated an abundance of contrary drives and impulses within himself: thanks to this synthesis, he is master of the earth.
|
|
From:
John Richardson (Nietzsche's System [2002], §966)
|
|
A reaction:
If this is true, it presents the fundamental challenge of politicial philosophy - to visual a successful social system for a creature which does not have a clear and focused nature. For Nietzsche, this 'synthesis' continually evolves.
