| 17260 | Imagination is just weakened sensation [Hobbes] |
| Full Idea: Imagination is nothing else but sense decaying or weakened by the absence of the object. | |
| From: Thomas Hobbes (De Corpore (Elements, First Section) [1655], 4.25.07) | |
| A reaction: This sounds more like memory than imagination. He needs to say something about unusual combinations of memories, I would have thought. |
| 9088 | Skill comes from a general assumption obtained from thinking about similar things [Aristotle] |
| Full Idea: A skill arises when from the many cases of thinking in experience a single general assumption is formed in connection with similar things. | |
| From: Aristotle (Metaphysics [c.324 BCE], 0981a04) | |
| A reaction: [He gives the administration of appropriate medicine as the example of a 'skill'] Note that it is 'thinking in' experience, rather than just the raw having of experiences. This is the intellectualist version of empirical abstractionism. I like it. |
| 16153 | Aristotle distinguishes two different sorts of generality - kinds, and properties [Aristotle, by Frede,M] |
| Full Idea: Aristotle counts as general not only properties but also the kinds, into which objects fall, i.e. the genera, species, and differentiae of substances; and these are to be differentiated strictly from properties. | |
| From: report of Aristotle (Metaphysics [c.324 BCE], kind) by Michael Frede - Individuals in Aristotle Intro | |
| A reaction: I take properties to be prior, since the kind of a thing is presumably decided by its properties. I'm increasingly thinking that 'general', 'generality' and 'generalisation' are far more useful words in philosophy than other words in that area. |
| 9791 | Science is more accurate when it is prior and simpler, especially without magnitude or movement [Aristotle] |
| Full Idea: A scientific subject will possess more accuracy (i.e. simplicity) the more that it is about conceptually prior and simpler things, and so it will be more accurate without than with magnitude being involved, and above all being without movement. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1078a10) | |
| A reaction: Aristotle is especially concerned to show how we can achieve accuracy, even while abstracting away from the details of the objects we are studying. Frege should have studied Aristotle more closely. |
| 19373 | A 'conatus' is an initial motion, experienced by us as desire or aversion [Hobbes, by Arthur,R] |
| Full Idea: Hobbes' notion of 'conatus' is a 'beginning of motion' - a motion through a point of space in an instant of time. In a human subject this is experience as desire or aversion. It thus forms a bridge between physics and psychology. | |
| From: report of Thomas Hobbes (De Corpore (Elements, First Section) [1655], p.178) by Richard T.W. Arthur - Leibniz 3 'Worlds' | |
| A reaction: This sounds rather like the primitive concept of a power which I like, but the term seems to be used very vaguely, and never discussed carefully. The idea provoked Leibniz to connect physical force with mental life. |
