| 17962 | The truth-maker principle is that every truth has a sufficient truth-maker [Forrest] |
| Full Idea: Item x is said to be a sufficient truth-maker for truth-bearer p just in case necessarily if x exists then p is true. ...Every truth has a sufficient truth-maker. Hence, I take it, the sum of all sufficient truth-makers is a universal truth-maker. | |
| From: Peter Forrest (General Facts,Phys Necessity, and Metaph of Time [2006], 1) | |
| A reaction: Note that it is not 'necessary', because something else might make p true instead. |
| 9565 | Zermelo made 'set' and 'member' undefined axioms [Zermelo, by Chihara] |
| Full Idea: The terms 'set' and 'is a member of' are primitives of Zermelo's 1908 axiomatization of set theory. They are not given model-theoretic analyses or definitions. | |
| From: report of Ernst Zermelo (works [1920]) by Charles Chihara - A Structural Account of Mathematics 7.5 | |
| A reaction: This looks like good practice if you want to work with sets, but not so hot if you are interested in metaphysics. |
| 3339 | For Zermelo's set theory the empty set is zero and the successor of each number is its unit set [Zermelo, by Blackburn] |
| Full Idea: For Zermelo's set theory the empty set is zero and the successor of each number is its unit set. | |
| From: report of Ernst Zermelo (works [1920]) by Simon Blackburn - Oxford Dictionary of Philosophy p.280 |
| 16625 | In hylomorphism all the explanation of actions is in the form, and the matter doesn't do anything [Bacon] |
| Full Idea: Prime, common matter seems to be a kind of accessory and to stand as a substratum, whereas any kind of action seems to be a mere emanation of form. So it is that forms are given all the leading parts. | |
| From: Francis Bacon (Philosophical Studies 1611-19 [1617], p.206), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 07.2 | |
| A reaction: This is a very striking criticism of hylomorphism. The revolution was simple - that actually matter seems to do all the real work, and the form can take a back seat. |
| 16624 | Stripped and passive matter is just a human invention [Bacon] |
| Full Idea: Stripped and passive matter seems nothing more than an invention of the human mind. | |
| From: Francis Bacon (Philosophical Studies 1611-19 [1617], p.206), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 07.2 | |
| A reaction: Bacon seems to me to get too little credit in the history of philosophy, because he is just seen as a progenitor of science. His modern views predate most radical 17th C thought by 20 years. |
