| 5896 | Speak the truth, for this alone deifies man [Pythagoras, by Porphyry] |
| Full Idea: Pythagoras advised above all things to speak the truth, for this alone deifies man. | |
| From: report of Pythagoras (reports [c.530 BCE]) by Porphyry - Life of Pythagoras §41 | |
| A reaction: Idea 4421 (of Nietzsche) stands in contrast to this. I am not quite sure why speaking the truth has such a high value. I am inclined to a minimalist view, which is just that philosophy is an attempt to speak the truth, as fishermen try to catch fish. |
| 3051 | Pythagoras discovered the numerical relation of sounds on a string [Pythagoras, by Diog. Laertius] |
| Full Idea: Pythagoras discovered the numerical relation of sounds on a string. | |
| From: report of Pythagoras (reports [c.530 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 08.1.11 |
| 21489 | Super-ordinate disciplines give laws or principles; subordinate disciplines give concrete cases [Peirce, by Atkin] |
| Full Idea: In Peirce's system, a super-ordinate discipline provides general laws or principles for subordinate disciplines, which in turn provide concrete examples of those general laws. | |
| From: report of Charles Sanders Peirce (works [1892]) by Albert Atkin - Peirce 1 'System' | |
| A reaction: Does he really mean that subordinate disciplines have no principles or laws? That can't be right. |
| 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. |
| 19095 | Pragmatic 'truth' is a term to cover the many varied aims of enquiry [Peirce, by Misak] |
| Full Idea: In Peirce's naturalist view of truth, it is a catch-all for the particular local aims of enquiry - empirical adequacy, predictive power, coherence, simplicity, elegance, explanatory power, a reliable guide to action, fruitfulness, great understanding. | |
| From: report of Charles Sanders Peirce (works [1892]) by Cheryl Misak - Pragmatism and Deflationism 1 | |
| A reaction: The aims I cited in my thesis on explanation. One given, for me, is that truth is an ideal, which may or may not be attainable, to varying degrees. It is just what thinking aims at. I suspect, though, that these listed items have one thing in common. |
| 19097 | Peirce did not think a belief was true if it was useful [Peirce, by Misak] |
| Full Idea: Peirce was not in the slightest bit tempted by the thought that a belief is true if it is useful. | |
| From: report of Charles Sanders Peirce (works [1892]) by Cheryl Misak - Pragmatism and Deflationism 2 | |
| A reaction: All students of the pragmatic theory of truth should start with this idea, because it rejects the caricature view of pragmatic truth, a view which is easily rebutted. James seems to have been guilty of this sin. |
| 21494 | If truth is the end of enquiry, what if it never ends, or ends prematurely? [Atkin on Peirce] |
| Full Idea: Two related worries about Peirce's account of truth are (from Royce) what are we to make of truth if enquiry never reaches an end, and (from Russell) what are we to make of truth if enquiry ends prematurely? | |
| From: comment on Charles Sanders Peirce (works [1892]) by Albert Atkin - Peirce 3 'issues' | |
| A reaction: The defence of Peirce must be that the theory is not holistic - referring to the whole Truth about absolutely everything. The discovery of the periodic table seems to me to support Peirce. In many areas basic enquiry has reached an end. |
| 21493 | Pure mathematics deals only with hypotheses, of which the reality does not matter [Peirce] |
| Full Idea: The pure mathematician deals exclusively with hypotheses. Whether or not there is any corresponding real thing, he does not care. | |
| From: Charles Sanders Peirce (works [1892], CP5.567), quoted by Albert Atkin - Peirce 3 'separation' | |
| A reaction: [Dated 1902] Maybe we should identify a huge branch of human learning as Hyptheticals. Professor of Hypotheticals at Cambridge University. The trouble is it would have to include computer games. So why does maths matter more than games? |
| 19102 | Bivalence is a regulative assumption of enquiry - not a law of logic [Peirce, by Misak] |
| Full Idea: Peirce takes bivalence not to be a law of logic, but a regulative assumption of enquiry. | |
| From: report of Charles Sanders Peirce (works [1892]) by Cheryl Misak - Pragmatism and Deflationism 2 n10 | |
| A reaction: I like this. For most enquiries it's either true or not true, it's either there or it's not there. When you aren't faced with these simple dichotomies (in history, or quantum mechanics) you can relax, and allow truth value gaps etc. |
| 7485 | For Pythagoreans 'one' is not a number, but the foundation of numbers [Pythagoras, by Watson] |
| Full Idea: For Pythagoreans, one, 1, is not a true number but the 'essence' of number, out of which the number system emerges. | |
| From: report of Pythagoras (reports [c.530 BCE], Ch.8) by Peter Watson - Ideas Ch.8 | |
| A reaction: I think this is right! Counting and numbers only arise once the concept of individuality and identity have arisen. Counting to one is no more than observing the law of identity. 'Two' is the big adventure. |
| 10352 | The real is the idea in which the community ultimately settles down [Peirce] |
| Full Idea: The real is the idea in which the community ultimately settles down. | |
| From: Charles Sanders Peirce (works [1892]), quoted by Martin Kusch - Knowledge by Agreement Ch.16 | |
| A reaction: If this is anti-realism, then I don't like it. If it is realist, then it is probably a bit on the optimistic side (if you think about cultures that are into witchcraft and voodoo). |
| 13498 | Peirce and others began the mapping out of relations [Peirce, by Hart,WD] |
| Full Idea: It was Peirce and Schröder in the nineteenth century who began a systematic taxonomy of relations. | |
| From: report of Charles Sanders Peirce (works [1892], 4) by William D. Hart - The Evolution of Logic 4 |
| 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. |
| 21491 | Peirce's later realism about possibilities and generalities went beyond logical positivism [Peirce, by Atkin] |
| Full Idea: The realism about possibilities, generalities, tendencies and habits that we find in Peirce's later maxim is something that the logical positivists would have been uncomfortable with. | |
| From: report of Charles Sanders Peirce (works [1892]) by Albert Atkin - Peirce 2 'Concl' | |
| A reaction: Atkin examines the various later statements of the earlier maxim, given here in Idea 21490. Ryle and Quine express the empiricist and logical positivist approach to dispositions. |
| 16376 | The possible can only be general, and the force of actuality is needed to produce a particular [Peirce] |
| Full Idea: The possible is necessarily general…..It is only actuality, the force of existence, which bursts the fluidity of the general and produces a discrete unit. | |
| From: Charles Sanders Peirce (works [1892]), quoted by François Recanati - Mental Files 13.1 | |
| A reaction: [Papers 4 1967:147] This was quoted by Prior, and is often cited. Recanati is interested in the notion of a singular thought being tied to actuality, by generating a mental file. |
| 19107 | Inquiry is not standing on bedrock facts, but standing in hope on a shifting bog [Peirce] |
| Full Idea: Inquiry is not standing upon a bedrock of fact. It is walking up a bog, and can only say, this ground seems to hold for the present. Here I will stay until it begins to give way. | |
| From: Charles Sanders Peirce (works [1892], CP 5.589), quoted by Gottfried Leibniz - Letter to Newton 4 | |
| A reaction: [I don't know which article this lovely quote comes from] |
| 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. |
| 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. |
| 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. |
| 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. |
| 3053 | Pythagoras taught that virtue is harmony, and health, and universal good, and God [Pythagoras, by Diog. Laertius] |
| Full Idea: Pythagoras taught that virtue is harmony, and health, and universal good, and God. | |
| From: report of Pythagoras (reports [c.530 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 08.1.19 | |
| A reaction: I like the link with health, because I consider that a bridge over the supposed fact-value gap. Very Pythagorean to think that virtue is harmony. Plato liked that thought. |
| 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. |
| 5244 | For Pythagoreans, justice is simply treating all people the same [Pythagoras, by Aristotle] |
| Full Idea: Some even think that what is just is simple reciprocity, as the Pythagoreans maintained, because they defined justice simply as having done to one what one has done to another. | |
| From: report of Pythagoras (reports [c.530 BCE], 28) by Aristotle - Nicomachean Ethics 1132b22 | |
| A reaction: One wonders what Pythagoreans made of slavery. Aristotle argues that officials, for example, have superior rights. The Pythagorean idea makes fairness the central aspect of justice, and that must at least be partly right. |
| 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]. |
| 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? |
| 638 | Pythagoreans define timeliness, justice and marriage in terms of numbers [Pythagoras, by Aristotle] |
| Full Idea: The Pythagoreans offered definitions of a limited range of things on the basis of numbers; examples are timeliness, justice and marriage. | |
| From: report of Pythagoras (reports [c.530 BCE]) by Aristotle - Metaphysics 1078b |
| 553 | Pythagoreans think mathematical principles are the principles of all of nature [Pythagoras, by Aristotle] |
| Full Idea: The Pythagoreans thought that the principles of mathematical entities were the principles of all entities. | |
| From: report of Pythagoras (reports [c.530 BCE]) by Aristotle - Metaphysics 985b |
| 375 | When musical harmony and rhythm were discovered, similar features were seen in bodily movement [Pythagoras, by Plato] |
| Full Idea: When our predecessors discovered musical scales, they also discovered similar features in bodily movement, which should also be measured numerically, and called 'tempos' and 'measures'. | |
| From: report of Pythagoras (reports [c.530 BCE]) by Plato - Philebus 17d |
| 554 | Pythagoreans say things imitate numbers, but Plato says things participate in numbers [Pythagoras, by Aristotle] |
| Full Idea: Pythagoreans said that entities existed by imitation of the numbers, whereas Plato said that it was by participation. | |
| From: report of Pythagoras (reports [c.530 BCE]) by Aristotle - Metaphysics 987b |
| 644 | For Pythagoreans the entire universe is made of numbers [Pythagoras, by Aristotle] |
| Full Idea: For Pythagoreans the entire universe is constructed of numbers. | |
| From: report of Pythagoras (reports [c.530 BCE]) by Aristotle - Metaphysics 1080b |
| 7467 | The modern idea of an immortal soul was largely created by Pythagoras [Pythagoras, by Watson] |
| Full Idea: The modern concept of the immortal soul is a Greek idea, which owes much to Pythagoras. | |
| From: report of Pythagoras (reports [c.530 BCE]) by Peter Watson - Ideas Ch.5 | |
| A reaction: You can see why it caught on - it is a very appealing idea. Watson connects the 'modern' view with the ideas of heaven and hell. Obviously the idea of an afterlife goes a long way back (judging from the contents of ancient graves). |
