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) |
23247 | The need to act produces consciousness, and practical reason is the root of all reason [Fichte] |
Full Idea: Consciousness of the real world proceeds from the need to act, not the other way around. …Practical reason is the root of all reason. | |
From: Johann Fichte (The Vocation of Man [1800], 3.I) | |
A reaction: Strongly agree with the last part. In my conceptual scheme 'sensible' behaviour (e.g. of animals) precedes, in every way, rational behaviour. Sensible attitudes to quantity and magnitude precede mathematical logic. Minds exist for navigation. |
23232 | Sufficient reason makes the transition from the particular to the general [Fichte] |
Full Idea: The principle of sufficient reason is the point of transition from the particular, which is itself, to the general, which is outside it. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: Not sure I understand this, but it seems worth passing on. Personally I would say that we have a knack of generalising, triggered when we spot patterns. |
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. |
15130 | If a property is possible, there is something which can have it [Williamson] |
Full Idea: Barcan's axiom says if there can be something that has a certain property, then there is something that can have that property. It and its converse are not obviously correct or incorrect. They claim that it is non-contingent what individuals there are. | |
From: Timothy Williamson (Laudatio: Prof Ruth Barcan Marcus [2011], p.1) | |
A reaction: Williamson defends the two Barcan formulas, but the more I understand them the less plausible they sound to me. |
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. |
23227 | Each object has a precise number of properties, each to a precise degree [Fichte] |
Full Idea: Each object has a definite number of properties, no more, no less. …Each of these objects possesses each of these properties to a definite degree. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: Quine flatly disagrees with this. Fichte offers no grounds for his claim. On the whole I think of properties as psychologically abstracted by us from holistic objects, so there is plenty of room for error. The underlying powers are real. |
23228 | The principle of activity and generation is found in a self-moving basic force [Fichte] |
Full Idea: The principle of activity, of generation and becoming in and for itself, is purely in that force itself and not in anything outside it…; the force is not driven or set in motion, it sets itself in motion. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: A good account of primitive powers, as self-motivating forces. I can't think what else could be fundamental to nature. This whole passage of Fichte expounds a powers ontology. |
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. |
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. |
23241 | I am myself, but not the external object; so I only sense myself, and not the object [Fichte] |
Full Idea: I sense in myself, not in the object, for I am myself and not the object; therefore I sense only myself and my condition, and not the condition of the object. | |
From: Johann Fichte (The Vocation of Man [1800], 2) | |
A reaction: I'm not clear why anyone would have total confidence in internal experience and almost no confidence in experience of externals. In daily life I am equally confident about both. In philosophical mode I make equally cautious judgements about both. |
21969 | Awareness of reality comes from the free activity of consciousness [Fichte] |
Full Idea: It is the necessary faith in our freedom of power, in our own real activity, and in the definite laws of human action, which lies at the root of all our consciousness of a reality external to ourselves. | |
From: Johann Fichte (The Vocation of Man [1800], p.98), quoted by A.W. Moore - The Evolution of Modern Metaphysics 06.4 | |
A reaction: I'd love to know what the 'laws of human action' are. Is it what Hume was trying to do? Moore says there is an 'element of self-creation' in Fichte's account of the source of reality. This is Descartes' dream argument biting back. |
21966 | Self-consciousness is the basis of knowledge, and knowing something is knowing myself [Fichte] |
Full Idea: The immediate consciousness of myself is the condition of all other consciousness; and I know a thing only in so far as I know that I know it; no element can enter into the latter cognition which is not contained in the former. | |
From: Johann Fichte (The Vocation of Man [1800], p.37), quoted by A.W. Moore - The Evolution of Modern Metaphysics 06.2 | |
A reaction: This strikes me as false, and a lot of intellectual contortion would be needed to believe it. Is knowing this pen is in front of me a case of knowing that I have knowledge of this pen, or is it just knowledge of this pen? [cf Kant 1781:A129] |
21967 | There is nothing to say about anything which is outside my consciousness [Fichte] |
Full Idea: Of any connection beyond the limits of my consciousness I cannot speak. ...I cannot proceed a hair's breadth beyond this consciousness, any more than I can spring out of myself. | |
From: Johann Fichte (The Vocation of Man [1800], p.74), quoted by A.W. Moore - The Evolution of Modern Metaphysics 06.3 | |
A reaction: I can't see that this is any different from the idealism of Berkeley, although they get there from different starting points. Idealist seem unable to even begin explaining consciousness. |
23231 | I immediately know myself, and anything beyond that is an inference [Fichte] |
Full Idea: Immediately I know only of myself. What I am able to know beyond that I am only able to know through inference. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: A direct descendant of the Cartesian Cogito, I assume. Personally, if I bang my head on a beam I take the beam to be a full paid-up member of reality. Is it not possible that he also knows himself through inference? Do animals infer reality? |
23246 | Faith is not knowledge; it is a decision of the will [Fichte] |
Full Idea: Faith is no knowledge, but a decision of the will to recognise the validity of knowledge. | |
From: Johann Fichte (The Vocation of Man [1800], 3.I) | |
A reaction: What matters is the grounds for the decision. Mad conspiracy theories are decisions of the will which are false. Legitimate faith is an intuition of coherence which cannot be fully articulated. |
23245 | Knowledge can't be its own foundation; there has to be regress of higher and higher authorities [Fichte] |
Full Idea: No knowledge can be its own foundation and proof. Every knowledge presupposes something still higher as its foundation, and this ascent has no end. | |
From: Johann Fichte (The Vocation of Man [1800], 3.I) | |
A reaction: A metaphor that's hard to visualise! He must have in mind a priori as well as empirical knowledge. The 'higher' levels don't seem to be God, but some region of absolute rationality, to which free minds have access. I think. |
23242 | Consciousness has two parts, passively receiving sensation, and actively causing productions [Fichte] |
Full Idea: My immediate consciousness is composed of two constituent parts, the consciousness of my passivity, the sensation; and the consciousness of my activity, in the production of an object according to the principle of causality. | |
From: Johann Fichte (The Vocation of Man [1800], 2) | |
A reaction: Kind of obvious, but unusual to make this sharp binary division. Modern neuroscience strongly militates against any and every simple binary division of brain activities. |
23240 | We can't know by sight or hearing without realising that we are doing so [Fichte] |
Full Idea: Q. Could you not perhaps know an object through sight or hearing without knowing that you are seeing or hearing? A. Not at all. | |
From: Johann Fichte (The Vocation of Man [1800], 2) | |
A reaction: A nice statement of the traditional view which seemed to be demolished by the discovery of blindsight. In the light of modern brain research, the views of the mind found in past philosophers mostly seem very naïve. |
23243 | Consciousness of external things is always accompanied by an unnoticed consciousness of self [Fichte] |
Full Idea: Q. So that constantly and under all circumstances my consciousness of things outside of me is accompanied by an unnoticed consciousness of myself? A. Quite so. | |
From: Johann Fichte (The Vocation of Man [1800], 2) | |
A reaction: He should be more cautious about asserting the existence of something 'unnoticed'. The Earth's core is unnoticed by me, but there is plenty of evidence for it. Not so sure about unnoticed self. Still, I think central control of the mind is indispensable. |
23244 | Forming purposes is absolutely free, and produces something from nothing [Fichte] |
Full Idea: My thinking and originating of a purpose is in its nature absolutely free and brings forth something from nothing. | |
From: Johann Fichte (The Vocation of Man [1800], 3.I) | |
A reaction: Modern fans of free will are more equivocal in their assertions, and would be uncomfortable bluntly claiming to 'get something from nothing'. But that's what free will is! Embrace it, or run for your life. |
23237 | The capacity for freedom is above the laws of nature, with its own power of purpose and will [Fichte] |
Full Idea: This capacity [for freedom], once it exists, is in the servitude of a power which is higher than nature and quite free of its laws, the power of purposes, and the will. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: You would think this could only refer to God, but he in fact is referring to the power of human free will. The clearest statement I have found of the weird human exceptionalism implied by a strong commitment to free will. |
23235 | I want independent control of the fundamental cause of my decisions [Fichte] |
Full Idea: I want to be independent - not to be in and through another but to be something for myself: and as such I want myself to be the fundamental cause of all my determinations. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: I think this sums up the absurdity of the concept of free will. The only reason he gives for his passionate belief in free will is that he desperately wants some imagined 'fundamental cause' for his action, and he wants full control of that chimera. |
23230 | Nature contains a fundamental force of thought [Fichte] |
Full Idea: There is an original force of thought in nature just as there is an original formative force. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: I think this idea is false, but it helps to understand Fichte. |
23233 | The will is awareness of one of our inner natural forces [Fichte] |
Full Idea: To will is to be immediately conscious of the activity of one of our inner natural forces. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: A more Nietzschean view would be that to will is to be conscious of the victor among our inner natural drives. It can't just be awareness of one force, because the will feels conflicts. |
23234 | I cannot change the nature which has been determined for me [Fichte] |
Full Idea: I cannot will the intention of making myself something other than what I am determined to be by nature, for I don't make myself at all but nature makes me and whatever I become. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: I take this to be a lot more accurate than Sartre's claim that we can re-make ourselves, but Fichte doesn't seem quite right. Don't I get any credit at all if I give up smoking, or train myself to treat someone more sympathetically? |
23239 | The self is, apart from outward behaviour, a drive in your nature [Fichte] |
Full Idea: This 'you' for which you show such a lively interest is, so far as it is not overt behaviour, at least a drive in your own peculiar nature. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: I assume this use of 'drive' is the origin of Nietzsche's picture of such things, focused on the basic will to power. I like Fichte's emphasis on active forces as the basis of nature. |
23238 | If life lacks love it becomes destruction [Fichte] |
Full Idea: Only in love is there life; without it there is death and annihilation. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: He gives not context of justification for this sudden claim. Watching from a melancholy distance the current 2022 Russian invasion of Ukraine, I take this idea to be a profound truth. If you let go of love, you float away down a dark stream. |
23236 | Freedom means making yourself become true to your essential nature [Fichte] |
Full Idea: I want to be free means: I myself want to make myself be whatever I will be. I would therefore …already have to be, in a certain sense, what I am to become, so that I could make myself be it. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: This is much closer to the existenial picture of the malleable self, which Fichte arrives out once he commits to his desperate desire to have free will. [Not sure if my gist captures what he says]. |
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) |
23229 | Nature is wholly interconnected, and the tiniest change affects everything [Fichte] |
Full Idea: Nature is an interconnected whole; …you could shift no grain of sand from its spot without thereby, perhaps invisibly to your eyes, changing something in all parts of the immeasurable whole. | |
From: Johann Fichte (The Vocation of Man [1800], 1) | |
A reaction: Sounds like idealist daydreaming, but might it actually be true with respect to gravity? |
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) |
