48 ideas

2. Reason / A. Nature of Reason / 1. On Reason
1502 Parmenides was much more cautious about accepting ideas than his predecessors [Simplicius on Parmenides]
7. Existence / A. Nature of Existence / 3. Being / a. Nature of Being
448 No necessity could produce Being either later or earlier, so it must exist absolutely or not at all [Parmenides]
447 Being must be eternal and uncreated, and hence it is timeless [Parmenides]
449 Being is not divisible, since it is all alike [Parmenides]
7. Existence / A. Nature of Existence / 3. Being / d. Non-being
1503 There is no such thing as nothing [Parmenides]
445 The realm of necessary non-existence cannot be explored, because it is unknowable [Parmenides]
7. Existence / A. Nature of Existence / 3. Being / f. Primary being
21820 Parmenides at least saw Being as the same as Nous, and separate from the sensed realm [Parmenides, by Plotinus]
7. Existence / B. Change in Existence / 1. Nature of Change
452 All our concepts of change and permanence are just names, not the truth [Parmenides]
7. Existence / E. Categories / 1. Categories
17377 All descriptive language is classificatory [Dupré]
7. Existence / E. Categories / 2. Categorisation
17376 We should aim for a classification which tells us as much as possible about the object [Dupré]
8. Modes of Existence / B. Properties / 13. Tropes / a. Nature of tropes
10467 Individuals consist of 'compresent' tropes [Bacon,John]
10464 A trope is a bit of a property or relation (not an exemplification or a quality) [Bacon,John]
10465 Trope theory is ontologically parsimonious, with possibly only one-category [Bacon,John]
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
17390 Natural kinds don't need essentialism to be explanatory [Dupré]
9. Objects / D. Essence of Objects / 10. Essence as Species
17389 A species might have its essential genetic mechanism replaced by a new one [Dupré]
17388 It seems that species lack essential properties, so they can't be natural kinds [Dupré]
9. Objects / E. Objects over Time / 1. Objects over Time
1504 Something must be unchanging to make recognition and knowledge possible [Aristotle on Parmenides]
10. Modality / A. Necessity / 5. Metaphysical Necessity
444 The first way of enquiry involves necessary existence [Parmenides]
10. Modality / A. Necessity / 8. Transcendental Necessity
450 Necessity sets limits on being, in order to give it identity [Parmenides]
10. Modality / E. Possible worlds / 2. Nature of Possible Worlds / a. Nature of possible worlds
10466 Maybe possible worlds are just sets of possible tropes [Bacon,John]
11. Knowledge Aims / B. Certain Knowledge / 4. The Cogito
451 Thinking implies existence, because thinking depends on it [Parmenides]
12. Knowledge Sources / B. Perception / 1. Perception
1506 Parmenides treats perception and intellectual activity as the same [Theophrastus on Parmenides]
12. Knowledge Sources / C. Rationalism / 1. Rationalism
3058 Only reason can prove the truth of facts [Parmenides]
14. Science / A. Basis of Science / 4. Prediction
17374 The possibility of prediction rests on determinism [Dupré]
18. Thought / C. Content / 5. Twin Earth
17378 Presumably molecular structure seems important because we never have the Twin Earth experience [Dupré]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / e. The One
555 People who say that the cosmos is one forget that they must explain movement [Aristotle on Parmenides]
5081 There could be movement within one thing, as there is within water [Aristotle on Parmenides]
1509 The one can't be divisible, because if it was it could be infinitely divided down to nothing [Parmenides, by Simplicius]
20900 Defenders of the One say motion needs the void - but that is not part of Being [Parmenides, by Aristotle]
226 The one is without any kind of motion [Parmenides]
