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! |
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. |
541 | Virtue comes more from habit than character [Critias] |
Full Idea: More men are good through habit than through character. | |
From: Critias (fragments/reports [c.440 BCE], B09), quoted by John Stobaeus - Anthology 3.29.41 |
22230 | Sartre gradually realised that freedom is curtailed by the weight of situation [Sartre, by Daigle] |
Full Idea: Sartre evolved from a notion of absolute freedom to one that truly takes into account the weight of situation. | |
From: report of Jean-Paul Sartre (works [1950]) by Christine Daigle - Jean-Paul Sartre 2.3 | |
A reaction: This change seems to have come much later, in the 1960s. The main influence seems to have been Marxism, which claims that consciousness is created by society, rather than by free individuals. |
542 | Fear of the gods was invented to discourage secret sin [Critias] |
Full Idea: When the laws forbade men to commit open crimes of violence, and they began to do them in secret, a wise and clever man invented fear of the gods for mortals, to frighten the wicked, even if they sin in secret. | |
From: Critias (fragments/reports [c.440 BCE], B25), quoted by Sextus Empiricus - Against the Professors (six books) 9.54 |
