Definitions formed an abstract hierarchy for Aristotle, as sets do for us [Fine,K]
|
|
Full Idea:
For us it is sets which constitute the most natural example of a hierarchical structure within the abstract realm; but for Aristotle it would have been definitions, via their natural division into genus and differentia.
|
|
From:
Kit Fine (Aristotle on Matter [1992], §1 n4)
|
|
A reaction:
I suppose everyone who thinks about reality in abstraction ends up with a hierarchy. Compare the hierarchy of angelic hosts, or Greek gods. Could we get back to the Aristotelian view, instead of sets, which are out of control at the top end?

There is no distinctive idea of constitution, because you can't say constitution begins and ends [Fine,K]
|
|
Full Idea:
If the parts of a body can constitute a man, then why should men not constitute a family? Why draw the line at the level of the man? ...Thus the idea of a distinctive notion of constitution, terminating in concrete substances, should be given up.

From:
Kit Fine (Aristotle on Matter [1992], 1)
|
|
A reaction:
This is in the context of Aristotle, but Fine's view seems to apply to Rudder Baker's distinctive approach.

Is there a plausible Aristotelian notion of constitution, applicable to both physical and non-physical? [Fine,K]
|
|
Full Idea:
There is a question of whether there is a viable conception of constitution of the sort Aristotle supposes, one which is uniformly applicable to physical and non-physical objects alike, and which is capable of hierarchical application.

|
From:
Kit Fine (Aristotle on Matter [1992], 1)
|
|
A reaction:
This is part of an explication of Aristotle's 'matter' [hule], which might be better translated as 'ingredients', which would fit non-physical things quite well.

Lewis must specify that all possibilities are in his worlds, making the whole thing circular [Shalkowski, by Sider]
|
|
Full Idea:
If purple cows are simply absent from Lewis's multiverse, then certain correct propositions turn out to be impossible. Lewis must require a world for every possibility. But then it is circular, as the multiverse needs modal notions to characterize it.
|
|
From:
report of Scott Shalkowski (Ontological Ground of Alethic Modality [1994], 3.9) by Theodore Sider - Reductive Theories of Modality 3.9
|
|
A reaction:
[Inversely, a world containing a round square would make that possible] This sounds very nice, though Sider rejects it (p.197). I've never seen how you could define possibility using the concept of 'possible' worlds.

The concept of mind excludes body, and vice versa [Descartes]
|
|
Full Idea:
The concept of body includes nothing at all which belongs to the mind, and the concept of mind includes nothing at all which belongs to the body.
|
|
From:
René Descartes (Reply to Fourth Objections [1641], 225)
|
|
A reaction:
A headache? Hunger? The mistake, I think, is to regard the mind as entirely conscious, thus creating a sharp boundary between two aspects of our lives. As shown by blindsight, I take many of my central mental operations to be pre- or non-conscious.
