224 | When questions are doubtful we should concentrate not on objects but on ideas of the intellect [Plato] |
Full Idea: Doubtful questions should not be discussed in terms of visible objects or in relation to them, but only with reference to ideas conceived by the intellect. | |
From: Plato (Parmenides [c.364 BCE], 135e) |
24084 | Seeing with other eyes is more egoism, but exploring other perspectives leads to objectivity [Nietzsche] |
Full Idea: Wanting to know things as they are - that alone is the good inclination: not seeing ..with other eyes; that would be merely a change of place of egoistic seeing. …Practise at seeing with other eyes, and without human relationships, hence objectively! | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 11[013]) | |
A reaction: That Nietzsche thinks we should try to see things objectively will come as a bit of a shock to those who have him catalogued among the relativists. It's clear from other writings that he thinks (rightly) that perfect objectivity is unattainable. |
232 | Opposites are as unlike as possible [Plato] |
Full Idea: Opposites are as unlike as possible. | |
From: Plato (Parmenides [c.364 BCE], 159a) |
8937 | Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic [Hegel on Plato] |
Full Idea: Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic. | |
From: comment on Plato (Parmenides [c.364 BCE]) by Georg W.F.Hegel - Phenomenology of Spirit Pref 71 | |
A reaction: It is a long way from the analytic tradition of philosophy to be singling out a classic text for its 'artistic' achievement. Eventually we may even look back on, say, Kripke's 'Naming and Necessity' and see it in that light. |
24092 | I tell the truth, even if it is repulsive [Nietzsche] |
Full Idea: As a man I tell the truth, even the repulsive ones. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 12[86]) | |
A reaction: I wonder if even Nietzsche had his limits. He is quite coy about sexual matters, for example, before Freud and various sexual revolutions. To ruthlessly tell difficult truths strikes me as a scientific approach to the world. |
13986 | Plato found antinomies in ideas, Kant in space and time, and Bradley in relations [Plato, by Ryle] |
Full Idea: Plato (in 'Parmenides') shows that the theory that 'Eide' are substances, and Kant that space and time are substances, and Bradley that relations are substances, all lead to aninomies. | |
From: report of Plato (Parmenides [c.364 BCE]) by Gilbert Ryle - Are there propositions? 'Objections' |
14150 | Plato's 'Parmenides' is perhaps the best collection of antinomies ever made [Russell on Plato] |
Full Idea: Plato's 'Parmenides' is perhaps the best collection of antinomies ever made. | |
From: comment on Plato (Parmenides [c.364 BCE]) by Bertrand Russell - The Principles of Mathematics §337 |
16150 | One is, so numbers exist, so endless numbers exist, and each one must partake of being [Plato] |
Full Idea: If one is, there must also necessarily be number - Necessarily - But if there is number, there would be many, and an unlimited multitude of beings. ..So if all partakes of being, each part of number would also partake of it. | |
From: Plato (Parmenides [c.364 BCE], 144a) | |
A reaction: This seems to commit to numbers having being, then to too many numbers, and hence to too much being - but without backing down and wondering whether numbers had being after all. Aristotle disagreed. |
229 | The one was and is and will be and was becoming and is becoming and will become [Plato] |
Full Idea: The one was and is and will be and was becoming and is becoming and will become. | |
From: Plato (Parmenides [c.364 BCE], 155d) | |
A reaction: This seems to be rhetorical, rather a precise theory, given that the One is said to be eternal and unchanging. The One is not just what we call 'reality'. |
21821 | Plato's Parmenides has a three-part theory, of Primal One, a One-Many, and a One-and-Many [Plato, by Plotinus] |
Full Idea: The Platonic Parmenides is more exact [than Parmenides himself]; the distinction is made between the Primal One, a strictly pure Unity, and a secondary One which is a One-Many, and a third which is a One-and-Many. | |
From: report of Plato (Parmenides [c.364 BCE]) by Plotinus - The Enneads 5.1.08 | |
A reaction: Plotinus approves of this three-part theory. Parmenides has the problem that the highest Being contains no movement. By placing the One outside Being you can give it powers which an existent thing cannot have. Cf the concept of God. |
221 | Absolute ideas, such as the Good and the Beautiful, cannot be known by us [Plato] |
Full Idea: The absolute good and the beautiful and all which we conceive to be absolute ideas are unknown to us. | |
From: Plato (Parmenides [c.364 BCE], 134c) | |
A reaction: These seems to thoroughly pre-empt Plato's Theory of Forms a century before he created it. Which shows (as Simone Weil says) that Plato was just part of a long tradition. |
227 | You must always mean the same thing when you utter the same name [Plato] |
Full Idea: You must always mean the same thing when you utter the same name. | |
From: Plato (Parmenides [c.364 BCE], 147d) |
223 | If you deny that each thing always stays the same, you destroy the possibility of discussion [Plato] |
Full Idea: If a person denies that the idea of each thing is always the same, he will utterly destroy the power of carrying on discussion. | |
From: Plato (Parmenides [c.364 BCE], 135c) |
210 | It would be absurd to think there were abstract Forms for vile things like hair, mud and dirt [Plato] |
Full Idea: Are there abstract ideas for such things as hair, mud and dirt, which are particularly vile and worthless? That would be quite absurd. | |
From: Plato (Parmenides [c.364 BCE], 130d) |
219 | If absolute ideas existed in us, they would cease to be absolute [Plato] |
Full Idea: None of the absolute ideas exists in us, because then it would no longer be absolute. | |
From: Plato (Parmenides [c.364 BCE], 133c) |
228 | Greatness and smallness must exist, to be opposed to one another, and come into being in things [Plato] |
Full Idea: These two ideas, greatness and smallness, exist, do they not? For if they did not exist, they could not be opposites of one another, and could not come into being in things. | |
From: Plato (Parmenides [c.364 BCE], 149e) |
211 | If admirable things have Forms, maybe everything else does as well [Plato] |
Full Idea: It is troubling that if admirable things have abstract ideas, then perhaps everything else must have ideas as well. | |
From: Plato (Parmenides [c.364 BCE], 130d) |
220 | The concept of a master includes the concept of a slave [Plato] |
Full Idea: Mastership in the abstract is mastership of slavery in the abstract. | |
From: Plato (Parmenides [c.364 BCE], 133e) |
16151 | Plato moves from Forms to a theory of genera and principles in his later work [Plato, by Frede,M] |
Full Idea: It seems to me that Plato in the later dialogues, beginning with the second half of 'Parmenides', wants to substitute a theory of genera and theory of principles that constitute these genera for the earlier theory of forms. | |
From: report of Plato (Parmenides [c.364 BCE]) by Michael Frede - Title, Unity, Authenticity of the 'Categories' V | |
A reaction: My theory is that the later Plato came under the influence of the brilliant young Aristotle, and this idea is a symptom of it. The theory of 'principles' sounds like hylomorphism to me. |
215 | If things partake of ideas, this implies either that everything thinks, or that everything actually is thought [Plato] |
Full Idea: If all things partake of ideas, must either everything be made of thoughts and everything thinks, or everything is thought, and so can't think? | |
From: Plato (Parmenides [c.364 BCE], 132c) |
212 | The whole idea of each Form must be found in each thing which participates in it [Plato] |
Full Idea: The whole idea of each form (of beauty, justice etc) must be found in each thing which participates in it. | |
From: Plato (Parmenides [c.364 BCE], 131a) |
213 | Each idea is in all its participants at once, just as daytime is a unity but in many separate places at once [Plato] |
Full Idea: Just as day is in many places at once, but not separated from itself, so each idea might be in all its participants at once. | |
From: Plato (Parmenides [c.364 BCE], 131b) |
216 | If things are made alike by participating in something, that thing will be the absolute idea [Plato] |
Full Idea: That by participation in which like things are made like, will be the absolute idea, will it not? | |
From: Plato (Parmenides [c.364 BCE], 132e) |
218 | Participation is not by means of similarity, so we are looking for some other method of participation [Plato] |
Full Idea: Participation is not by means of likeness, so we must seek some other method of participation. | |
From: Plato (Parmenides [c.364 BCE], 133a) |
217 | Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) [Plato] |
Full Idea: It is impossible for anything to be like an absolute idea, because a third idea will appear to make them alike, and if that is like anything, it will lead to another idea, and so on. | |
From: Plato (Parmenides [c.364 BCE], 133a) |
214 | If absolute greatness and great things are seen as the same, another thing appears which makes them seem great [Plato] |
Full Idea: If you regard the absolute great and the many great things in the same way, will not another appear beyond, by which all these must appear to be great? | |
From: Plato (Parmenides [c.364 BCE], 132a) |
15851 | Parts must belong to a created thing with a distinct form [Plato] |
Full Idea: The part would not be the part of many things or all, but of some one character ['ideas'] and of some one thing, which we call a 'whole', since it has come to be one complete [perfected] thing composed [created] of all. | |
From: Plato (Parmenides [c.364 BCE], 157d) | |
A reaction: A serious shot by Plato at what identity is. Harte quotes it (125) and shows that 'character' is Gk 'idea', and 'composed' will translate as 'created'. 'Form' links this Platonic passage to Aristotle's hylomorphism. |
15846 | In Parmenides, if composition is identity, a whole is nothing more than its parts [Plato, by Harte,V] |
Full Idea: At the heart of the 'Parmenides' puzzles about composition is the thesis that composition is identity. Considered thus, a whole adds nothing to an ontology that already includes its parts | |
From: report of Plato (Parmenides [c.364 BCE]) by Verity Harte - Plato on Parts and Wholes 2.5 | |
A reaction: There has to be more to a unified identity that mere proximity of the parts. When do parts come together, and when do they actually 'compose' something? |
15849 | Plato says only a one has parts, and a many does not [Plato, by Harte,V] |
Full Idea: In 'Parmenides' it is argued that a part cannot be part of a many, but must be part of something one. | |
From: report of Plato (Parmenides [c.364 BCE], 157c) by Verity Harte - Plato on Parts and Wholes 3.2 | |
A reaction: This looks like the right way to go with the term 'part'. We presuppose a unity before we even talk of its parts, so we can't get into contradictions and paradoxes about their relationships. |
15850 | Anything which has parts must be one thing, and parts are of a one, not of a many [Plato] |
Full Idea: The whole of which the parts are parts must be one thing composed of many; for each of the parts must be part, not of a many, but of a whole. | |
From: Plato (Parmenides [c.364 BCE], 157c) | |
A reaction: This is a key move of metaphysics, and we should hang on to it. The other way madness lies. |
13259 | It seems that the One must be composed of parts, which contradicts its being one [Plato] |
Full Idea: The One must be composed of parts, both being a whole and having parts. So on both grounds the One would thus be many and not one. But it must be not many, but one. So if the One will be one, it will neither be a whole, nor have parts. | |
From: Plato (Parmenides [c.364 BCE], 137c09), quoted by Kathrin Koslicki - The Structure of Objects 5.2 | |
A reaction: This is the starting point for Plato's metaphysical discussion of objects. It seems to begin a line of thought which is completed by Aristotle, surmising that only an essential structure can bestow identity on a bunch of parts. |
24089 | Essences are fictions needed for beings who represent things [Nietzsche] |
Full Idea: The true essence of things is a fiction of representing being, without which being is unable to represent. 11[330] Thinking must assert substance and identity because a knowing of complete flux is impossible. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 11[329]) | |
A reaction: I have defended (in my PhD) the thesis that the concept of essence is required for explanation. Do animals need the concept of essence in order to represent? I think people and animals ascribe essential natures to most things. |
15847 | Two things relate either as same or different, or part of a whole, or the whole of the part [Plato] |
Full Idea: Everything is surely related to everything as follows: either it is the same or different; or, if it is not the same or different, it would be related as part to whole or as whole to part. | |
From: Plato (Parmenides [c.364 BCE], 146b) | |
A reaction: This strikes me as a really helpful first step in trying to analyse the nature of identity. Two things are either two or (actually) one, or related mereologically. |
19000 | Read 'all ravens are black' as about ravens, not as about an implication [Belnap] |
Full Idea: 'All ravens are black' might profitably be read as saying not that being a raven 'implies' being black, but rather something more like 'Consider the ravens: each one is black'. | |
From: Nuel D. Belnap (Conditional Assertion and Restricted Quantification [1970], p.7), quoted by Stephen Yablo - Aboutness 04.5 | |
A reaction: Belnap is more interested in the logic than in the paradox of confirmation, since he evidently thinks that universal generalisations should not be read as implications. I like Belnap's suggestion. |
24090 | Our inclinations would not conflict if we were a unity; we imagine unity for our multiplicity [Nietzsche] |
Full Idea: How is it that we satisfy our stronger inclinations at the expense of our weaker inclinations? - In itself, if we were a unity, this split could not exist. In fact we are a multiplicity that has imagined a unity for itself. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 12[35]) | |
A reaction: Plato had the same thought, but stopped at three parts, rather than a multiplicity. What Nietzsche fails to say, I think, is that this 'imagined' unity of the mind is not optional, and obviously has a real link to the one body and the one life. |
24087 | People who miss beauty seek the sublime, where even the ugly shows its 'beauty' [Nietzsche] |
Full Idea: Whoever does not achieve the beautiful seeks the wildly sublime, because there even the ugly can show its 'beauty'. Likewise we seek the wildly sublime morality. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 11[049]) | |
A reaction: Is the 'we' here Nietzsche, or the herd? The former, I guess, since some the values he likes seem rather ugly to me. He is a fan of war, for example. I'm guessing that massive destruction is sublime but ugly. |
24091 | The sublimity of nature which dwarfs us was a human creation [Nietzsche] |
Full Idea: This beauty and sublimity of nature, before which every human being seems small, was first imposed on nature by us. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 12[38]) | |
A reaction: I was struck when I was 10 with how indifferent to a landscape I was, when my mother told me it was 'beautiful'. Five years later I saw it differently. I assume nature is not intrinsically sublime. Dwarfed by our own concept is a bit odd. |
24093 | We can aspire to greatness by creating new functions for ourselves [Nietzsche] |
Full Idea: To see the new greatness not above oneself, not outside oneself, but to make a new function from it. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 13[19]) | |
A reaction: Thus we might combine the Aristotelian and the existentialist views! Do we discover our function or invent it? Anyone who acquires an expertise is creating a new function for themselves, presumably with a high value. |
24085 | For absolute morality a goal for mankind is needed [Nietzsche] |
Full Idea: I deny absolute morality because I do not know an absolute goal of mankind. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 11[037]) | |
A reaction: Christianity dreams of union of souls with God (clustering around God like goldfish to food, according to Dante). That is an absolute goal, justifying an absolute morality. If Aristotelians could identify human nature, its flourishing might be absolute. |
24094 | Humans are vividly aware of short-term effects, and almost ignorant of the long-term ones [Nietzsche] |
Full Idea: How weakly human beings feel responsible for their indirect and distant effects! And how cruelly and exaggeratedly the closest effect that we exert pounces on us - the effect we see, for which our myopic vision is still just sharp enough! | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 15[11]) | |
A reaction: This strikes me as both accurate and important, because consequentialist ethics is largely committed to judging by a very distorted image of their own objective. |
24086 | The goal is to settle human beings, like other animals, but humans are still changeable [Nietzsche] |
Full Idea: Obviously the goal is to make human beings as steady and firm as most animal species; they have adapted to the conditions of the earth etc. and do not change essentially. The human being is still changeable - is still becoming. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 11[044]) | |
A reaction: I favour an Aristotelian view, based on the flourishing of human nature, but this thought obviously challenges such a view. Great changes to a culture can make some difference to the apparent nature of people. |
24088 | See our present lives as eternal! Religions see it as fleeting, and aim at some different life [Nietzsche] |
Full Idea: Let us press the image of eternity on our life! This thought contains more than all religions that despise this life as fleeting and taught us to look toward an unspecified different life. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 11[159]) | |
A reaction: This is the best statement of the idea of eternal recurrence I have so far found. His ideal is to design a life for ourselves which we would be happy to see endlessly repeated. A lot of thought would have to go into that! |
222 | Only a great person can understand the essence of things, and an even greater person can teach it [Plato] |
Full Idea: Only a man of very great natural gifts will be able to understand that everything has a class and absolute essence, and an even more wonderful man can teach this. | |
From: Plato (Parmenides [c.364 BCE], 135a) |
24095 | Our growth is too subtle to perceive, and long events are too slow for us to grasp [Nietzsche] |
Full Idea: The slowness of the events in the history of human beings is not suited to the human sense of time - and the subtlety and smallness of all growth defies human vision. | |
From: Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 15[41]) | |
A reaction: The only way we can study history is by 'periods'. It is as if English history has its slate wiped clean in 1066, 1485, 1603 and 1689. All historians know that the reality of it all is totally beyond our grasp. |
225 | The unlimited has no shape and is endless [Plato] |
Full Idea: The unlimited partakes neither of the round nor of the straight, because it has no ends nor edges. | |
From: Plato (Parmenides [c.364 BCE], 137e) |
233 | Some things do not partake of the One [Plato] |
Full Idea: The others cannot partake of the one in any way; they can neither partake of it nor of the whole. | |
From: Plato (Parmenides [c.364 BCE], 159d) | |
A reaction: Compare Idea 231 |
2062 | The only movement possible for the One is in space or in alteration [Plato] |
Full Idea: If the One moves it either moves spatially or it is altered, since these are the only motions. | |
From: Plato (Parmenides [c.364 BCE], 138b) |
231 | Everything partakes of the One in some way [Plato] |
Full Idea: The others are not altogether deprived of the one, for they partake of it in some way. | |
From: Plato (Parmenides [c.364 BCE], 157c) | |
A reaction: Compare Idea 233. |
234 | We couldn't discuss the non-existence of the One without knowledge of it [Plato] |
Full Idea: There must be knowledge of the one, or else not even the meaning of the words 'if the one does not exist' would be known. | |
From: Plato (Parmenides [c.364 BCE], 160d) |
