| 23227 | Each object has a precise number of properties, each to a precise degree [Fichte] |
| Full Idea: Each object has a definite number of properties, no more, no less. …Each of these objects possesses each of these properties to a definite degree. | |
| From: Johann Fichte (The Vocation of Man [1800], 1) | |
| A reaction: Quine flatly disagrees with this. Fichte offers no grounds for his claim. On the whole I think of properties as psychologically abstracted by us from holistic objects, so there is plenty of room for error. The underlying powers are real. |
| 15728 | The naturalness of a class depends as much on the observers as on the objects [Quinton] |
| Full Idea: The naturalness of a class depends as essentially on the nature of the observers who classify as it does on the nature of the objects that they classify. ...It depends on our perceptual apparatus, and on our relatively mutable needs and interests. | |
| From: Anthony Quinton (The Nature of Things [1973], 9 'Nat') | |
| A reaction: This seems to translate 'natural' as 'natural for us', which is not much use to scientists, who spend quite a lot of effort combating folk wisdom. Do desirable sports cars constitute a natural class? |
| 9407 | Properties imply natural classes which can be picked out by everybody [Quinton] |
| Full Idea: To say there are properties is to say there are natural classes, classes introduction to some of whose members enables people to pick out others without hesitation and in agreement. | |
| From: Anthony Quinton (The Nature of Things [1973], 9 'Nat') | |
| A reaction: Aristotle would like this approach, but it doesn't find many friends among modern logician/philosophers. We should go on to ask why people agree on these things. Causal powers will then come into it. |
| 23228 | The principle of activity and generation is found in a self-moving basic force [Fichte] |
| Full Idea: The principle of activity, of generation and becoming in and for itself, is purely in that force itself and not in anything outside it…; the force is not driven or set in motion, it sets itself in motion. | |
| From: Johann Fichte (The Vocation of Man [1800], 1) | |
| A reaction: A good account of primitive powers, as self-motivating forces. I can't think what else could be fundamental to nature. This whole passage of Fichte expounds a powers ontology. |
| 15729 | Uninstantiated properties must be defined using the instantiated ones [Quinton] |
| Full Idea: Properties that have no concrete instances must be defined in terms of those that have. | |
| From: Anthony Quinton (The Nature of Things [1973], 9 'Nat') | |
| A reaction: I wonder what the dodo used to smell like? |
