8797 | The negation of all my beliefs about my current headache would be fully coherent [Sosa] |
Full Idea: If I have a headache, I could have a set of beliefs that I do not have a headache, that I am not in pain, that no one is in pain, and so on. The resulting system of beliefs would cohere as fully as does my actual system of beliefs. | |
From: Ernest Sosa (The Raft and the Pyramid [1980], §9) | |
A reaction: I think this is a misunderstanding of coherentism. Beliefs are not to be formulated through a process of coherence, but are evaluated that way. A belief that I have headache just arrives; I then see that its denial is incoherent, so I accept it. |
5311 | If observation goes up a level, we expect the laws of the lower level to remain in force [Wilson,EO] |
Full Idea: When the observer shifts his attention from one level of organisation to the next, as from physics to chemistry, he expects to find obedience to all the laws of the levels below. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.1) | |
A reaction: This seems to state a necessary condition of reduction, but not a sufficient one. Wilson points out that new phenomena emerge at higher levels. This principle is similar to Hume's argument against miracles. You don't easily overthrow basic laws. |
5312 | A child first sees objects as distinct, and later as members of groups [Wilson,EO] |
Full Idea: From a single-minded effort to move objects a child's activity grows into a detached reflection on the movements themselves. The objects are first perceived as distinct entities, and then as members of groups to be classified. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.3) | |
A reaction: This does not, of course, prove anything about the philosophical problems of universals, but it does seem to pinpoint the stage in human development when 'universals' are perceived. The basis seems to be groups or sets, but how do we spot those? |
16078 | 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. |
16077 | 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. |
16080 | 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? |
16076 | 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'. |
16081 | 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'. |
16082 | 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. |
5309 | Beliefs are really enabling mechanisms for survival [Wilson,EO] |
Full Idea: Beliefs are really enabling mechanisms for survival. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.1) | |
A reaction: How does he know this proposition which he asserts so confidently? Obvious counterexamples seem to be utterly trivial beliefs, and self-destructive beliefs. What is the evolutionary value of low self-esteem? Still, you see his point. |
8794 | There are very few really obvious truths, and not much can be proved from them [Sosa] |
Full Idea: Radical foundationalism suffers from two weaknesses: there are not so many perfectly obvious truths as Descartes thought; and if we restrict ourselves to what it truly obvious, very little supposed common sense knowledge can be proved. | |
From: Ernest Sosa (The Raft and the Pyramid [1980], §3) | |
A reaction: It is striking how few examples can ever be found of self-evident a priori truths. However, if there are self-evident truths about direct experience (pace Descartes), that would give us more than enough. |
8796 | A single belief can trail two regresses, one terminating and one not [Sosa] |
Full Idea: A single belief can trail at once regresses of both sorts: one terminating and one not. | |
From: Ernest Sosa (The Raft and the Pyramid [1980], §6) | |
A reaction: This makes foundationalism possible, while admitting the existence of regresses. It is a good point, and triumphalist anti-foundationalists can't just point out a regress and then smugly troop off to the pub. |
8799 | If mental states are not propositional, they are logically dumb, and cannot be foundations [Sosa] |
Full Idea: If a mental state is not propositional, then how can it possibly serve as a foundation for belief? How can one infer or justify anything on the basis of a state that, having no propositional content, must be logically dumb? | |
From: Ernest Sosa (The Raft and the Pyramid [1980], §11) | |
A reaction: This may be the best objection to foundationalism. McDowell tries to argue that conceptual content is inherent in perception, thus giving the beginnings of inbuilt propositional content. But an organism awash with bare experiences knows nothing. |
8795 | Mental states cannot be foundational if they are not immune to error [Sosa] |
Full Idea: If a mental state provides no guarantee against error, then it cannot serve as a foundation for knowledge. | |
From: Ernest Sosa (The Raft and the Pyramid [1980], §4) | |
A reaction: That assumes that knowledge entails certainty, which I am sure it should not. On a fallibilist account, a foundation could be incredibly secure, despite a barely imaginable scenario in which it turned out to be false. |
8798 | Vision causes and justifies beliefs; but to some extent the cause is the justification [Sosa] |
Full Idea: Visual experience is recognized as both the cause and the justification of our visual beliefs. But these are not wholly independent. Presumably the justification that something is red derives partly from the fact that it originates in visual experience. | |
From: Ernest Sosa (The Raft and the Pyramid [1980], §10) | |
A reaction: Yes, but the fact that certain visual experiences originate in dreams is taken as grounds for denying their truth, not affirming it. So why do we distinguish them? I am thinking that only in the 'space of reasons' can a cause become a justification. |
5310 | Philosophers study the consequences of ethics instead of its origins [Wilson,EO] |
Full Idea: Philosophers examine the precepts of ethical systems with reference to their consequences and not their origins. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.1) | |
A reaction: He is interested in biological origins, but it strikes me that every moral theory has some account of the origins of morality, be it pure reason, or the love of pleasure, or human nature, or eternal ideas, or the will of God, or selfish desires. |
5313 | The rules of human decision-making converge and overlap in a 'human nature' [Wilson,EO] |
Full Idea: The rules followed in human decision-making are tight enough to produce a broad overlap in the decisions taken by all individuals, and hence a convergence powerful enough to be labelled 'human nature'. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.3) | |
A reaction: This is a nice empirical criterion for asserting the existence of human nature, and it seems right to examine decisions, rather than more thoughtless or conformist behaviour. Existentialists dream of new possibilities, but the old ways always seem best… |
5316 | We undermine altruism by rewarding it, but we reward it to encourage it [Wilson,EO] |
Full Idea: By sanctifying altruism in order to reward it we make it less true, but by that means we promote its recurrence in others. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.7) | |
A reaction: So is my preference for not rewarding (or even noticing) altruism an anti-social tendency. The very conspicuous charity of sponsorship seems somehow inferior to the truly anonymous gift. Or super-altruism is very public, to encourage it in others? |
5318 | Pure hard-core altruism based on kin selection is the enemy of civilisation [Wilson,EO] |
Full Idea: Pure hard-core altruism based on kin selection is the enemy of civilisation. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.7) | |
A reaction: By 'hard-core' he means suicidally self-sacrificing, rather than extensive. This seems a good thesis. It strikes me that the development of civil society is often impeded by family loyalty, such as in the case of the Mafia. |
5317 | The actor is most convincing who believes that his performance is real [Wilson,EO] |
Full Idea: The actor is most convincing who believes that his performance is real. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.7) | |
A reaction: This is a key element of social contract theory. It shows why natural selection of truly altruistic traits might be beneficial to individuals, provided they are surrounded by possible recipricators. We trust those who are genuine and sincere. |
5308 | The only human purpose is that created by our genetic history [Wilson,EO] |
Full Idea: No species, ours included, possesses a purpose beyond the imperatives created by its genetic history. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.1) | |
A reaction: This invites the question of what that purpose is perceived to be. Some people feel an imperative to play the piano all day, so presumably genetic history has created that feeling. Presumably we can also choose a purpose, even extinction. |
5314 | Cultural evolution is Lamarckian and fast, biological evolution is Darwinian and slow [Wilson,EO] |
Full Idea: Cultural evolution is Lamarckian and very fast, whereas biological evolution is Darwinian and usually very slow. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.4) | |
A reaction: An intriguing point, given how discredited Lamarckian evolution is. It links with the Dawkins idea of 'memes' - cultural ideas which spread very fast. Is biological evolution suddenly about to become Lamarckian, as culture influences biology? |
5315 | Over 99 percent of human evolution has been in the hunter-gatherer phase [Wilson,EO] |
Full Idea: Selection pressures of hunter-gatherer existence have persisted for over 99 percent of human genetic evolution. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.4) | |
A reaction: This seems a key point to bear in mind when assessing human nature. Hunter-gathering isn't just one tendency in our genetics; it more or less constitutes everything we are. |
5320 | It is estimated that mankind has produced 100,000 religions [Wilson,EO] |
Full Idea: Since the first recorded religion (in Iraq 60,000 years ago) it is estimated that mankind has produced in the order of one hundred thousand religions. | |
From: Edmund O. Wilson (On Human Nature [1978], Ch.8) | |
A reaction: If asked to guess the number, I would probably have said '200'! This staggering figure seems to argue both ways - it suggest a certain arbitrariness in the details of religions, but an extremely intense drive to have some sort of religious belief. |
