| 20771 | Six parts: dialectic, rhetoric, ethics, politics, physics, theology [Cleanthes, by Diog. Laertius] |
| Full Idea: Cleanthes says there are six parts: dialectic, rhetoric, ethics, politics, physics, and theology. | |
| From: report of Cleanthes (fragments/reports [c.270 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.41 | |
| A reaction: This was a minority view, as most stoics agreed with Zeno and Chrysippus that there are three main topics. Nowadays there is little discussion of the 'parts' of philosophy, but the recent revival of meta-philosophy should encourage it. |
| 10496 | Monothetic categories have fixed defining features, and polythetic categories do not [Ellen] |
| Full Idea: Many categories are 'monothetic' (the defining set of features is always unique), and others are 'polythetic' (single features being neither essential to group membership nor sufficient to allocate an item to a group). | |
| From: Roy Ellen (Anthropological Studies of Classification [1996], p.33) | |
| A reaction: This seems a rather important distinction which hasn't made its way into philosophy, where there is a horrible tendency to oversimplify, with the dream of a neat and unified picture. But see Goodman's 'Imperfect Community' problem (Idea 7957). |
| 10497 | In symbolic classification, the categories are linked to rules [Ellen] |
| Full Idea: Symbolic classification occurs when we use some things as a means of saying something about other things. ..They enhance the significance of some categories, so that categories imply rules and rules imply categories. | |
| From: Roy Ellen (Anthropological Studies of Classification [1996], p.35) | |
| A reaction: I'm afraid the anthropologists seem to have more of interest to say about categories than philosophers do. Though maybe we couldn't do anthropology if philosophers had made us more self-conscious about categories. Teamwork! |
| 10494 | Several words may label a category; one word can name several categories; some categories lack words [Ellen] |
| Full Idea: Words are not always a good guide to the existence of categories: there may be several words which label the same categories (synonyms). and the same word can be used for quite different ideas. Some categories may exist without being labelled. | |
| From: Roy Ellen (Categories, Classification, Cogn. Anthropology [2006], I) | |
| A reaction: This is the sort of point which seems obvious to anyone outside philosophy, but which philosophers seem to find difficult to accept. Philosophers should pay much more attention to animals, and to illiterate peoples. Varieties of rice can lack labels. |
| 10495 | Continuous experience sometimes needs imposition of boundaries to create categories [Ellen] |
| Full Idea: Because parts of our experience of the world are complexly continuous, it is occasionally necessary to impose boundaries to produce categories at all. | |
| From: Roy Ellen (Anthropological Studies of Classification [1996], p.33) | |
| A reaction: I like it. Ellen says that people tend to universally cut nature somewhere around the joints, but we can't cope with large things, so the sea tends to be labelled in sections, even though most of the world's seas are continuous. |
| 10498 | Classification is no longer held to be rooted in social institutions [Ellen] |
| Full Idea: The view that all classification finds its roots in social institutions is now generally considered untenable. | |
| From: Roy Ellen (Anthropological Studies of Classification [1996], p.36) | |
| A reaction: And about time too. Ellen (an anthropologist) inevitably emphasises the complexity of the situation, but endorses the idea that people everywhere largely cut nature at the joints. |
| 6028 | Bodies interact with other bodies, and cuts cause pain, and shame causes blushing, so the soul is a body [Cleanthes, by Nemesius] |
| Full Idea: Cleanthes says no incorporeal interacts with a body, but one body interacts with another body; the soul interacts with the body when it is sick and being cut, and the body feels shame and fear, and turns red or pale, so the soul is a body. | |
| From: report of Cleanthes (fragments/reports [c.270 BCE]) by Nemesius - De Natura Hominis 78,7 | |
| A reaction: This is precisely the interaction problem with dualism, or, as we might now say, the problem of mental causation. The standard Stoic view is that the soul is a sort of rarefied fire, which disperses at death. |
| 20831 | The soul suffers when the body hurts, creates redness from shame, and pallor from fear [Cleanthes] |
| Full Idea: Nothing incorporeal shares an experience with a body …but the soul suffers with the body when it is ill and when it is cut, and the body suffers with the soul - when the soul is ashamed the body turns red, and pale when the soul is frightened. | |
| From: Cleanthes (fragments/reports [c.270 BCE]), quoted by Nemesius - De Natura Hominis 2 | |
| A reaction: Aha - my favourite example of the corporeal nature of the mind - blushing! It is the conscious content of the thought which brings blood to the cheeks. |
| 7257 | All modern social systems seem to be conspiracies of the rich [More,T] |
| Full Idea: When I consider any social system that prevails in the modern world, I can't see it as anything but a conspiracy of the rich to advance their own interests under the pretext of organizing society. | |
| From: Thomas More (Utopia [1516], Bk 2) | |
| A reaction: I'm afraid this is my own view of most conservative politics. I don't deny that there is a good case to be made for the conservative view (by Burke and Scruton, for example), but the rich will always latch onto its coat-tails. Cf. Idea 122. |
| 7254 | If you try to get elected, you should be permanently barred from seeking office [More,T] |
| Full Idea: In Utopia, anyone who deliberately tries to get himself elected to a public office is permanently disqualified from holding one. | |
| From: Thomas More (Utopia [1516], Bk 2) | |
| A reaction: This echoes a thought found in Plato (Idea 2149). I've always liked this idea. Why can't we have elections were a group of the best people are invited to stand? Well, yes, it would lead to corruption... Still, the best should be pushed to the front. |
| 7255 | Only Utopians fail to see glory in warfare [More,T] |
| Full Idea: Utopians are practically the only people on earth who fail to see anything glorious in war. | |
| From: Thomas More (Utopia [1516], Bk 2) | |
| A reaction: A refreshing thought for such an early date. Whatever dubious behaviour is nowadays attributed to Thomas More, you have to admire someone who writes this during the reign of Henry VIII. |
| 7253 | In Utopia, legal euthanasia is considered honourable [More,T] |
| Full Idea: In Utopia, officially sanctioned euthanasia is regarded as an honourable death. | |
| From: Thomas More (Utopia [1516], Bk 2) | |
| A reaction: A bit surprising coming from a writer who is now a Catholic martyr and saint. |
| 5993 | The ascending scale of living creatures requires a perfect being [Cleanthes, by Tieleman] |
| Full Idea: Cleanthes tried to prove the existence of God, arguing that the ascending scale of living creatures requires there to be a perfect being. | |
| From: report of Cleanthes (fragments/reports [c.270 BCE]) by Teun L. Tieleman - Cleanthes | |
| A reaction: Not a very good argument. Even if you accept its basic claim, it is not clear what has to exist. A perfect tree? If the being transcends the physical (in order to achieve perfection), does it cease to be a 'being'? |
| 7256 | In Utopia, the Supreme Being is identical with Nature [More,T] |
| Full Idea: Everyone in Utopia agrees that the Supreme Being (which they call Mythras) is identical with Nature. | |
| From: Thomas More (Utopia [1516], Bk 2) | |
| A reaction: This sounds remarkably like full-blown Spinozean pantheism, though it should be interpreted with caution. It certainly seems to show that pantheism was a possibility in the minds of late medieval religious thinkers. |
