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 |
13157 | Choose the true hypothesis, which is the most intelligible one [Leibniz] |
Full Idea: One should choose the more intelligible hypothesis, and the truth is nothing but its intelligibility. | |
From: Gottfried Leibniz (On Copernicanism and Relativity of Motion [1689], p.91) | |
A reaction: This apparently simple observation strikes me as being rather profound. Our picture of the world is shaped entirely by what is intelligible to us. An odd notion of truth, though. The age of reason. See Idea 13158. |
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. |
13158 | The Copernican theory is right because it is the only one offering a good explanation [Leibniz] |
Full Idea: The Copernican account is the truest theory, that is, the most intelligible theory and the only one capable of an explanation sufficient for a person of sound reason. | |
From: Gottfried Leibniz (On Copernicanism and Relativity of Motion [1689], p.92) | |
A reaction: The word 'intelligible' here seems to be linked to the notion of a best explanation. |
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. |
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. |
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 |
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 |
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 |
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 |
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 |
14349 | If there are no finks or antidotes at the fundamental level, the laws can't be ceteris paribus [Burge, by Corry] |
Full Idea: Bird argues that there are no finks at the fundamental level, and unlikely to be any antidotes. It then follows that laws at the fundamental level will all be strict - not ceteris paribus - laws. | |
From: report of Tyler Burge (Intellectual Norms and Foundations of Mind [1986]) by Richard Corry - Dispositional Essentialism Grounds Laws of Nature? 3 | |
A reaction: [Bird's main target is Nancy Cartwright 1999] This is a nice line of argument. Isn't part of the ceteris paribus problem that two fundamental laws might interfere with one another? |
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). |
