3 ideas
| 20653 | Six reduction levels: groups, lives, cells, molecules, atoms, particles [Putnam/Oppenheim, by Watson] |
| Full Idea: There are six 'reductive levels' in science: social groups, (multicellular) living things, cells, molecules, atoms, and elementary particles. | |
| From: report of H.Putnam/P.Oppenheim (Unity of Science as a Working Hypothesis [1958]) by Peter Watson - Convergence 10 'Intro' | |
| A reaction: I have the impression that fields are seen as more fundamental that elementary particles. What is the status of the 'laws' that are supposed to govern these things? What is the status of space and time within this picture? |
| 21867 | Conatus is brain circuits seeking survival and well-being [Damasio] |
| Full Idea: Conatus is explicable as the aggregate of dispositions laid down in brain circuitry that seeks both survival and well-being. | |
| From: Antonio Damasio (Looking for Spinoza [2003], p.36) | |
| A reaction: So conatus is the motivation of my inner personal assistant, who reminds me what I am doing later today. I like the mention of dispositions, hence powers. |
| 16689 | The schools said spirits lack extension, and wonder how many could dance on a needle's point [More,H] |
| Full Idea: Many, not without reason, laugh at those ridiculous fancies of the schools, that rashly take away all extensions from spirits, whether souls or angels, and then dispute how many of them booted and spurred may dance on a needle's point at once. | |
| From: Henry More (Immortality of the Soul [1659], III.2.1), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 17.3 | |
| A reaction: This famous idea originated with William Chillingworth. More's version is the classic one. Pasnau cites Aquinas Summa 1a 52.3 as discussing the actual question (and says this couldn't happen). |
