18 ideas

2. Reason / C. Styles of Reason / 1. Dialectic
Dialectic involves conversations with short questions and brief answers [Diog. Laertius]
     Full Idea: Dialectic is when men converse by putting short questions and giving brief answers to those who question them.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 3.1.52)
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
Clay is intrinsically and atomically the same as statue (and that lacks 'modal properties') [Rudder Baker]
     Full Idea: Arguments for statue being the clay are: that the clay is intrinsically like the statue, that the clay has the same atoms as the statue', that objects don't have modal properties such as being necessarily F, and the reference of 'property' changes.
     From: Lynne Rudder Baker (Why Constitution is not Identity [1997], II)
     A reaction: [my summary of the arguments she identifies - see text for details] Rudder Baker attempts to refute all four of these arguments, in defence of constitution as different from identity.
The clay is not a statue - it borrows that property from the statue it constitutes [Rudder Baker]
     Full Idea: I argue that a lump of clay borrows the property of being a statue from the statue. The lump is a statue because, and only because, there is something that the lump constitutes that is a statue.
     From: Lynne Rudder Baker (Why Constitution is not Identity [1997], n9)
     A reaction: It is skating on very thin metaphysical ice to introduce the concept of 'borrowing' a property. I've spent the last ten minutes trying to 'borrow' some properties, but without luck.
9. Objects / B. Unity of Objects / 3. Unity Problems / d. Coincident objects
Is it possible for two things that are identical to become two separate things? [Rudder Baker]
     Full Idea: A strong intuition shared by many philosophers is that some things that are in fact identical might not have been identical.
     From: Lynne Rudder Baker (Why Constitution is not Identity [1997], IV)
     A reaction: This flies in the face of the Kripkean view that if Hesperus=Phosphorus then the identity is necessary. I don't think I have an intuition that some given thing might have been two things - indeed the thought seems totally weird. Amoeba? Statue/clay?
9. Objects / C. Structure of Objects / 6. Constitution of an Object
Constitution is not identity, as consideration of essential predicates shows [Rudder Baker]
     Full Idea: I want to resuscitate an essentialist argument against the view that constitution is identity, of the form 'x is essentially F, y is not essentially F, so x is not y'.
     From: Lynne Rudder Baker (Why Constitution is not Identity [1997], Intro)
     A reaction: The point is that x might be essentially F and y only accidentally F. Thus a statue is essentially so, but a lump if clay is not essentially a statue. Another case where 'necessary' would do instead of 'essentially'.
The constitution view gives a unified account of the relation of persons/bodies, statues/bronze etc [Rudder Baker]
     Full Idea: Constitution-without-identity is superior to constitution-as-identity in that it provides a unified view of the relation between persons and bodies, statues and pieces of bronze, and so on.
     From: Lynne Rudder Baker (Why Constitution is not Identity [1997], IV)
     A reaction: I have a problem with the intrinsic dualism of this whole picture. Clay needs shape, statues need matter - there aren't two 'things' here which have a 'relation'.
Statues essentially have relational properties lacked by lumps [Rudder Baker]
     Full Idea: The statue has relational properties which the lump of clay does not have essentially.
     From: Lynne Rudder Baker (Why Constitution is not Identity [1997], V)
     A reaction: She has in mind relations to the community of artistic life. I don't think this is convincing. Is something only a statue if it is validated by an artistic community? That sounds like relative identity, which she doesn't like.
13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / a. Agrippa's trilemma
Sceptics say demonstration depends on self-demonstrating things, or indemonstrable things [Diog. Laertius]
     Full Idea: Sceptics say that every demonstration depends on things which demonstrates themselves, or on things which can't be demonstrated.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.Py.11)
     A reaction: This refers to two parts of Agrippa's Trilemma (the third being that demonstration could go on forever). He makes the first option sound very rationalist, rather than experiential.
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
Scepticism has two dogmas: that nothing is definable, and every argument has an opposite argument [Diog. Laertius]
     Full Idea: Sceptics actually assert two dogmas: that nothing should be defined, and that every argument has an opposite argument.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.Py.11)
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
When sceptics say that nothing is definable, or all arguments have an opposite, they are being dogmatic [Diog. Laertius]
     Full Idea: When sceptics say that they define nothing, and that every argument has an opposite argument, they here give a positive definition, and assert a positive dogma.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.11.11)
14. Science / C. Induction / 4. Reason in Induction
Induction moves from some truths to similar ones, by contraries or consequents [Diog. Laertius]
     Full Idea: Induction is an argument which by means of some admitted truths establishes naturally other truths which resemble them; there are two kinds, one proceeding from contraries, the other from consequents.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 3.1.23)
22. Metaethics / C. The Good / 3. Pleasure / b. Types of pleasure
Cyrenaic pleasure is a motion, but Epicurean pleasure is a condition [Diog. Laertius]
     Full Idea: Cyrenaics place pleasure wholly in motion, whereas Epicurus admits it as a condition.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 10.28)
     A reaction: Not a distinction we meet in modern discussions. Do events within the mind count as 'motion'? If so, these two agree. If not, I'd vote for Epicurus.
23. Ethics / A. Egoism / 1. Ethical Egoism
Cynics believe that when a man wishes for nothing he is like the gods [Diog. Laertius]
     Full Idea: Cynics believe that when a man wishes for nothing he is like the gods.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 6.Men.3)
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
The right-wing conception of freedom is based on the idea of self-ownership [Cohen,GA]
     Full Idea: The right-wing conception of freedom is, I think, founded on the idea that each person is the morally rightful owner of himself, even if existing legal systems do not acknowledge it. Let us call that the 'self-ownership' thesis.
     From: G.A. Cohen (Are Freedom and Equality Compatible? [1986], 1)
     A reaction: He cites Nozick as articulating this view. At the end Cohen rejects self-ownership, though he agrees that no one would accept that the state could be the owner of your eyes. Do I own my hair after it is cut?
Plenty of people have self-ownership, but still lack autonomy [Cohen,GA]
     Full Idea: Universal self-ownership fails to ensure autonomy, since it tends to produce proletarians, who lack it.
     From: G.A. Cohen (Are Freedom and Equality Compatible? [1986], 3)
     A reaction: The implication is that autonomy is not a property of individuals but a social phenomenon. Self-owning people can still be imprisoned. What about autonomy without self-ownership? A bright slave who is given extensive responsibility?
25. Social Practice / C. Rights / 4. Property rights
It is doubtful whether any private property was originally acquired legitimately [Cohen,GA]
     Full Idea: It is easy to doubt that much actually existing private property was formed in what anyone could think was a legitimating way.
     From: G.A. Cohen (Are Freedom and Equality Compatible? [1986], 2)
     A reaction: What if I created an artificial island out of unwanted raw materials? What about the first humans to reach some remote territory?
It is plausible that no one has an initial right to own land and natural resources [Cohen,GA]
     Full Idea: One may plausibly say of external things in their initial state, of raw land and natural resources, that no person has a greater right to them than any other does.
     From: G.A. Cohen (Are Freedom and Equality Compatible? [1986], 1)
     A reaction: How about if your group has lived on that plot for fifty generations, and some interlopers arrive and claim part of it. No one thought of 'owning' it till the interlopers arrived. Native Americans and Australians.
Every thing which is now private started out as unowned [Cohen,GA]
     Full Idea: In the prehistory of anything that is now private property there was at least one moment at which something privately unowned was taken into private ownership.
     From: G.A. Cohen (Are Freedom and Equality Compatible? [1986], 2)
     A reaction: He is obviously talking about land and natural resources. Presumably a table which I made and own was always private property, although the land where the trees were grown was not. Though in some communities what I make could be automatically communal.
