6. Mathematics / B. Foundations for Mathematics / 3. Axioms for Geometry
Archimedes defined a straight line as the shortest distance between two points [Archimedes, by Leibniz]
     Full Idea: Archimedes gave a sort of definition of 'straight line' when he said it is the shortest line between two points.
     From: report of Archimedes (fragments/reports [c.240 BCE]) by Gottfried Leibniz - New Essays on Human Understanding 4.13
     A reaction: Commentators observe that this reduces the purity of the original Euclidean axioms, because it involves distance and measurement, which are absent from the purest geometry.
15. Nature of Minds / A. Nature of Mind / 1. Mind / e. Questions about mind
Mindless bodies are zombies, bodiless minds are ghosts [Sturgeon]
     Full Idea: When bodies are conceived without mind, Zombies are the topic; when mind is conceived without bodies, Ghosts are the topic.
     From: Scott Sturgeon (Matters of Mind [2000], Intro)
     A reaction: Personally I am not too impressed by either possibility. I doubt whether either of them are even logically possible. Can you have a magnet without its magnetism? Can you have magnetism with no magnet?
Types are properties, and tokens are events. Are they split between mental and physical, or not? [Sturgeon]
     Full Idea: The question is whether mental and physical types (which are properties) are distinct, and whether mental and physical tokens (which are events) are distinct.
     From: Scott Sturgeon (Matters of Mind [2000], Intro)
     A reaction: Helpful. While the first one gives us the rather dodgy notion of 'property dualism', the second one seems to imply Cartesian dualism, if the events really are distinct. It seems to me that thought is an aspect of brain events, not a distinct event.
15. Nature of Minds / B. Features of Minds / 5. Qualia / b. Qualia and intentionality
Intentionality isn't reducible, because of its experiential aspect [Sturgeon]
     Full Idea: The link between Aboutness and consciousness, plus the latter's theoretical recalcitrance, have prevented reduction of the former.
     From: Scott Sturgeon (Matters of Mind [2000], Intro)
     A reaction: I remain unconvinced that Aboutness (intentionality) has to be wholly (or even partly conscious). We are more interested in our conscious mental states, because those are the ones we can report to other people, and discuss.
17. Mind and Body / D. Property Dualism / 1. Reductionism critique
Rule-following can't be reduced to the physical [Sturgeon]
     Full Idea: If you can't squeeze an 'ought' from an 'is', then the feature of normativity will prevent the reduction of Aboutness.
     From: Scott Sturgeon (Matters of Mind [2000], Intro)
     A reaction: A dubious argument. Hume's point is that no rational inference will get you from is to ought, but you can get there on a whim. I don't see normativity as being so intrinsically magical that it is irreducible.
17. Mind and Body / E. Mind as Physical / 5. Causal Argument
The main argument for physicalism is its simple account of causation [Sturgeon]
     Full Idea: The dominant empirical argument for physicalism is the Overdetermination Argument: physics is closed and complete, mind is causally efficacious, the world isn't choc-full of overdetermination, so the mind is physical as well.
     From: Scott Sturgeon (Matters of Mind [2000], Intro)
     A reaction: I find this argument utterly convincing. The idea that there is only one thing which is outside the interconnected causal nexus which seems to constitute the rest of reality, and that is a piece of meat inside our heads, strikes me as totally ridiculous.
18. Thought / C. Content / 10. Causal Semantics
Do facts cause thoughts, or embody them, or what? [Sturgeon]
     Full Idea: Does a thought relate to its truth conditions like a tree to its age, a bee dance to its target, or smoke to its cause?
     From: Scott Sturgeon (Matters of Mind [2000], Intro)
     A reaction: Nice question. Is truth the purpose of thoughts, or the cause of thoughts, or the constitution(?) of thoughts? I vote for the bee….but we mustn't confuse truth with truth-conditions.
20. Action / B. Preliminaries of Action / 1. Intention to Act / a. Nature of intentions
Intentions must be mutually consistent, affirm appropriate means, and fit the agent's beliefs [Bratman, by Wilson/Schpall]
     Full Idea: Bratman's three main norms of intention are 'internal consistency' (between a person's intentions), 'means-end coherence' (the means must fit the end), and 'consistency with the agent's beliefs' (especially intending to do and believing you won't do).
     From: report of Michael Bratman (Intention, Plans, and Practical Reason [1987]) by Wilson,G/Schpall,S - Action 4
     A reaction: These are controversial, but have set the agenda for modern non-reductive discussions of intention.
Intentions are normative, requiring commitment and further plans [Bratman, by Wilson/Schpall]
     Full Idea: Intentions involve normative commitments. We settle on intended courses, if there is no reason to reconsider them, and intentions put pressure on us to form further intentions in order to more efficiently coordinate our actions.
     From: report of Michael Bratman (Intention, Plans, and Practical Reason [1987]) by Wilson,G/Schpall,S - Action 4
     A reaction: [a compression of their summary] This distinguishes them from beliefs and desires, which contain no such normative requirements, even though they may point that way.
20. Action / B. Preliminaries of Action / 1. Intention to Act / b. Types of intention
Intention is either the aim of an action, or a long-term constraint on what we can do [Bratman, by Wilson/Schpall]
     Full Idea: We need to distinguish intention as an aim or goal of actions, and intentions as a distinctive state of commitment to future action, a state that results from and subsequently constrains our practical endeavours as planning agents.
     From: report of Michael Bratman (Intention, Plans, and Practical Reason [1987]) by Wilson,G/Schpall,S - Action 2
     A reaction: I'm not sure how distinct these are, given the obvious possibility of intermediate stages, and the embracing of any available short-cut. If I could mow my lawn with one blink, I'd do it.
20. Action / B. Preliminaries of Action / 1. Intention to Act / c. Reducing intentions
Bratman rejected reducing intentions to belief-desire, because they motivate, and have their own standards [Bratman, by Wilson/Schpall]
     Full Idea: Bratman motivated the idea that intentions are psychologically real and not reducible to desire-belief complexes by observing that they are motivationally distinctive, and subject to their own unique standards of rational appraisal.
     From: report of Michael Bratman (Intention, Plans, and Practical Reason [1987]) by Wilson,G/Schpall,S - Action 4
     A reaction: If I thought my belief was a bit warped, and my desire morally corrupt, my higher self might refuse to form an intention. If so, then Bratman is onto something. But maybe my higher self has its own beliefs and desires.
