| 7719 | European philosophy consists of a series of footnotes to Plato [Whitehead] |
| Full Idea: The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato. | |
| From: Alfred North Whitehead (Process and Reality [1929], p.39) | |
| A reaction: Outsiders think this is a ridiculous remark, but readers of Plato can only be struck by what a wonderful tribute Whitehead has come up with. I would say that at least 80% of this database deals with problems which were discussed at length by Plato. |
| 10656 | With 'extensive connection', boundary elements are not included in domains [Whitehead, by Varzi] |
| Full Idea: In Whitehead's theory of extensive connection, no boundary elements are included in the domain of quantification. ...His conception of space contains no parts of lower dimensions, such as points or boundary elements. | |
| From: report of Alfred North Whitehead (Process and Reality [1929]) by Achille Varzi - Mereology 3.1 | |
| A reaction: [Varzi says we should see B.L.Clarke 1981 for a rigorous formulation. Second half of the Idea is Varzi p.21] |
| 15389 | In Whitehead 'processes' consist of events beginning and ending [Whitehead, by Simons] |
| Full Idea: There are no items in Whitehead's ontology called 'processes'. Rather, the term 'process' refers to the way in which the basic things - which are still events - come into existence and cease to exist. Whitehead called this 'becoming'. | |
| From: report of Alfred North Whitehead (Process and Reality [1929]) by Peter Simons - Whitehead: process and cosmology 'The mature' |
| 16698 | Days exist, and yet they seem to be made up of parts which don't exist [Burley] |
| Full Idea: I grant that a successive being is composed out of non-beings, as is clear of a day, which is composed of non-entities. Some part of this day is past and some future, and yet this day is. | |
| From: Walter Burley (Commentary on 'Physics' [1325], III text 11,f.65rb), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 18.3 | |
| A reaction: The dilemma of Aristotle over time infected the scholastic attempt to give an account of successive entities. A day is a wonderfully elusive entity for a metaphysician. |
| 16690 | Unlike permanent things, successive things cannot exist all at once [Burley] |
| Full Idea: This is the difference between permanent and successive things: that a permanent thing exists all at once, or at least can exist all at once, whereas it is incompatible with a successive thing to exist all at once. | |
| From: Walter Burley (Commentary on 'Physics' [1325], III txt 11,f.65rb), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 18.1 | |
| A reaction: Permanent things sound like what are now called 'three-dimensional' objects, but scholastic 'entia successiva' are not the same as spacetime 'worms' or collections of temporal stages. |
| 16719 | The primary qualities are mixed to cause secondary qualities [Burley] |
| Full Idea: Secondary qualities are caused by a mixture of primary qualities. | |
| From: Walter Burley (De formis [1330], pars post p.65), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 21.2 | |
| A reaction: Like paint. He probably has in mind hot, cold, wet and dry as the primary qualities. |
| 6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
| Full Idea: Hermarchus said that animal killing is justified by considerations of human safety and nourishment and by animals' inability to form contractual relations of justice with us. | |
| From: report of Hermarchus (fragments/reports [c.270 BCE]) by David A. Sedley - Hermarchus | |
| A reaction: Could the last argument be used to justify torturing animals? Or could we eat a human who was too brain-damaged to form contracts? |
| 15247 | Whitehead held that perception was a necessary feature of all causation [Whitehead, by Harré/Madden] |
| Full Idea: On Whitehead's view, not only is a volitional sense of 'causal power' projected on to physical events, but 'perception in the causal mode' is literally ascribed to them. | |
| From: report of Alfred North Whitehead (Process and Reality [1929]) by Harré,R./Madden,E.H. - Causal Powers 3.II | |
| A reaction: This seems to be a close relative of Leibniz's monads. 'Perception' is a daft word for it, but in some way everything is 'responsive' to the things adjacent to it. |
| 16962 | Whitehead replaced points with extended regions [Whitehead, by Quine] |
| Full Idea: Whitehead tried to avoid points, and make do with extended regions and sets of regions. | |
| From: report of Alfred North Whitehead (Process and Reality [1929]) by Willard Quine - Existence and Quantification p.93 |
