22358 | Scientific objectivity lies in inter-subjective testing [Popper] |
Full Idea: The objectivity of scientific statements lies in the fact that they can be inter-subjectively tested. | |
From: Karl Popper (The Logic of Scientific Discovery [1934], p.22), quoted by Reiss,J/Spreger,J - Scientific Objectivity 2.4 | |
A reaction: Does this mean that objectivity is the same as consensus? A bunch of subjective prejudiced fools can reach a consensus. And in the middle of that bunch there can be one person who is objecfive. Sounds wrong. |
22188 | Give Nobel Prizes for really good refutations? [Gorham on Popper] |
Full Idea: Popper implies that we should be giving Nobel Prizes to scientists who use severe tests to show us what the world is not like! | |
From: comment on Karl Popper (The Logic of Scientific Discovery [1934]) by Geoffrey Gorham - Philosophy of Science 2 | |
A reaction: A lovely simple point. The refuters are important members of the scientific team, but not the leaders. |
7780 | Falsification is the criterion of demarcation between science and non-science [Popper, by Magee] |
Full Idea: According to Popper, falsification is the criterion of demarcation between science and non-science. | |
From: report of Karl Popper (The Logic of Scientific Discovery [1934]) by Bryan Magee - Popper Ch.3 | |
A reaction: If I propose something which might be falsified in a hundred years, is it science NOW? Suppose my theory appeared to be falsifiable, but (after much effort) it turned out not to be? Suppose I just see a pattern (like quark theory) in a set of facts? |
16830 | We don't only reject hypotheses because we have falsified them [Lipton on Popper] |
Full Idea: Popper's mistake is to hold that disconfirmation and elimination work exclusively through refutation. | |
From: comment on Karl Popper (The Logic of Scientific Discovery [1934]) by Peter Lipton - Inference to the Best Explanation (2nd) 05 'Explanation' | |
A reaction: The point is that we reject hypotheses even if they have not actually been refuted, on the grounds that they don't give a good explanation. I agree entirely with Lipton. |
6794 | If falsification requires logical inconsistency, then probabilistic statements can't be falsified [Bird on Popper] |
Full Idea: In Popper's sense of the word 'falsify', whereby an observation statement falsifies a hypothesis only by being logically inconsistent with it, nothing can ever falsify a probabilistic or statistical hypothesis, which is therefore unscientific. | |
From: comment on Karl Popper (The Logic of Scientific Discovery [1934]) by Alexander Bird - Philosophy of Science Ch.5 | |
A reaction: In general, no prediction can be falsified until the events occur. This seems to be Aristotle's 'sea fight' problem (Idea 1703). |
6795 | When Popper gets in difficulties, he quietly uses induction to help out [Bird on Popper] |
Full Idea: It is a feature of Popper's philosophy that when the going gets tough, induction is quietly called upon to help out. | |
From: comment on Karl Popper (The Logic of Scientific Discovery [1934]) by Alexander Bird - Philosophy of Science Ch.5 | |
A reaction: This appears to be the central reason for the decline in Popper's reputation as the saviour of science. It would certainly seem absurd to say that you know nothing when you have lots of verification but not a glimmer of falsification. |
3856 | Good theories have empirical content, explain a lot, and are not falsified [Popper, by Newton-Smith] |
Full Idea: Popper's principles are roughly that one theory is superior to another if it has greater empirical content, if it can account for the successes of the first theory, and if it has not been falsified (unlike the first theory). | |
From: report of Karl Popper (The Logic of Scientific Discovery [1934]) by W.H. Newton-Smith - The Rationality of Science I.6 |
7779 | There is no such thing as induction [Popper, by Magee] |
Full Idea: According to Popper, induction is a dispensable concept, a myth. It does not exist. There is no such thing. | |
From: report of Karl Popper (The Logic of Scientific Discovery [1934]) by Bryan Magee - Popper Ch.2 | |
A reaction: This is a nice bold summary of the Popper view - that falsification is the underlying rational activity which we mistakenly think is verification by repeated observations. Put like this, Popper seems to be wrong. We obviously learn from experiences. |
3860 | Science cannot be shown to be rational if induction is rejected [Newton-Smith on Popper] |
Full Idea: If Popper follows Hume in abandoning induction, there is no way in which he can justify the claims that there is growth of scientific knowledge and that science is a rational activity. | |
From: comment on Karl Popper (The Logic of Scientific Discovery [1934]) by W.H. Newton-Smith - The Rationality of Science III.3 |
8143 | Self is the rider, intellect the charioteer, mind the reins, and body the chariot [Anon (Upan)] |
Full Idea: Know that the Self (Atman) is the rider, and the body the chariot; that the intellect is the charioteer, and the mind the reins. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Katha') | |
A reaction: This strikes me as exactly right. Even my intellectual powers are servants of the self. This suggests the view of the mind as a tool, which does not seem to occur in modern discussions. |
8147 | We have an apparent and a true self; only the second one exists, and we must seek to know it [Anon (Upan)] |
Full Idea: There are two selves, the apparent self, and the real Self. Of these it is the real Self (Atman), and he alone, who must be felt as truly existing. To the man who has felt him as truly existing he reveals his innermost nature. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Katha') | |
A reaction: A central Hindu doctrine against which Buddhism rebelled, by denying the self altogether. I prefer the Hindu view. A desire to abandon the self just seems to be a desire for death. Knowledge of our essential self is more interesting. But see Idea 2932! |
8155 | Without speech we cannot know right/wrong, true/false, good/bad, or pleasant/unpleasant [Anon (Upan)] |
Full Idea: If there were no speech, neither right nor wrong would be known, neither the true nor the false, neither the good nor the bad, neither the pleasant nor the unpleasant. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Chandogya') | |
A reaction: This could stand as the epigraph for the whole of modern philosophy of language. However, the text goes on to say that mind is higher than speech. The test question is the mental capabilities of animals. Do they 'know' pleasure, or truth? |
1590 | The just man does not harm his enemies, but benefits everyone [Plato] |
Full Idea: First, Socrates, you told me justice is harming your enemies and helping your friends. But later it seemed that the just man, since everything he does is for someone's benefit, never harms anyone. | |
From: Plato (Clitophon [c.372 BCE], 410b) | |
A reaction: Socrates certainly didn't subscribe to the first view, which is the traditional consensus in Greek culture. In general Socrates agreed with the views later promoted by Jesus. |
8142 | The wise prefer good to pleasure; the foolish are drawn to pleasure by desire [Anon (Upan)] |
Full Idea: The wise prefer the good to the pleasant; the foolish, driven by fleshly desires, prefer the pleasant ot the good. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Katha') | |
A reaction: If you consider appropriate diet, this is too obvious to be worth saying. The complication is that it is doubtful whether a life without pleasure is wholly good, and even the pleasure of food is not bad. Of two good foods, prefer the pleasant one. |
8151 | Let your teacher be a god to you [Anon (Upan)] |
Full Idea: Let your teacher be a god to you. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Taittiriya') | |
A reaction: Yes indeed. The problem in the west is that we are committed to encouraging a critical and questioning attitude. A high value for knowledge must precede a high value for a teacher. |
8153 | By knowing one piece of clay or gold, you know all of clay or gold [Anon (Upan)] |
Full Idea: By knowing one lump of clay, all things made of clay are known; by knowing a nugget of gold, all things made of gold are known. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Chandogya') | |
A reaction: I can't think of a better basic definition of a natural kind. There is an inductive assumption, of course, which hits trouble when you meet fool's gold, or two different sorts of jade. But the concept of a natural kind is no more than this. |
8154 | Originally there must have been just Existence, which could not come from non-existence [Anon (Upan)] |
Full Idea: In the beginning there was Existence, One only, without a second. Some say that in the beginning there was non-existence only, and that out of that the universe was born. But how could such a thing be? How could existence be born of non-existence? | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Chandogya') | |
A reaction: A very rare instance of an argument in the Upanishads, arising out of a disagreement. The monotheistic religions have preferred to make God the eternal element, presumably because that raises his status, but is also explains the start as a decision. |
8148 | Brahma, supreme god and protector of the universe, arose from the ocean of existence [Anon (Upan)] |
Full Idea: Out of the infinite ocean of existence arose Brahma, first-born and foremost among the gods. From him sprang the universe, and he became its protector. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Mundaka') | |
A reaction: Brahma does not have eternal (or necessary) existence. Could Brahma cease to exist? I suppose we cannot ask what caused the appearance of Brahma? Is it part of a plan, or just luck, or some sort of necessity? |
8144 | Brahman is the Uncaused Cause [Anon (Upan)] |
Full Idea: Brahman is the Uncaused Cause. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Katha') | |
A reaction: This precedes Aquinas (Idea 1430) by over two thousand years. The theological trick is to admit one Uncaused Cause, but somehow exclude further instances, such as my bicycle getting a puncture. Does this undermine the Principle of Sufficient Reason? |
8152 | Earth, food, fire, sun are all forms of Brahman [Anon (Upan)] |
Full Idea: Earth, food, fire, sun - all these that you worship - are forms of Brahman. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Chandogya') | |
A reaction: In 'Taittiriya' food is named as the "chief of all things". Pantheism seems to arise from a desire that one's god should have every conceivable good, so in addition to power and knowledge, your god must keep you warm and healthy. |
8156 | The gods are not worshipped for their own sake, but for the sake of the Self [Anon (Upan)] |
Full Idea: It is not for the sake of the gods, my beloved, that the gods are worshipped, but for the sake of the Self (Atman). | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Brihadaranyaka') | |
A reaction: There is an uneasy selfish streak in all religions, which conflicts with their exhorations to altruism, and to the love of the gods. It also occurs in the exhortation of Socrates to be virtuous. 'Pure' altruism seems only to arise in the 18th century. |
8157 | A man with desires is continually reborn, until his desires are stilled [Anon (Upan)] |
Full Idea: A man acts according to desires; after death he reaps the harvest of his deeds, and returns again to the world of action. Thus he who has desires continues subject to rebirth, but he in who desire is stilled suffers no rebirth. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Brihadaranyaka') | |
A reaction: I greatly prefer the Stoic idea (Idea 3066) that we should live according to nature, to this perverse longing to completely destroy our own nature and become something we are not. Play the cards you are dealt, which include desires. |
8159 | Damayata - be self-controlled! Datta - be charitable! Dayadhwam - be compassionate! [Anon (Upan)] |
Full Idea: The storm-clouds thunder: Da! Da! Da! Damayata - be self-controlled! Datta - be charitable! Dayadhwam - be compassionate! | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Brihadaranyaka') | |
A reaction: Compassion seems to imply charity, so it comes down to 'Be self-controlled and compassionate'. Only the wildest romantic could be against self-control. Only Nietzsche could be against compassion (Idea 4425). |
8145 | Those ignorant of Atman return as animals or plants, according to their merits [Anon (Upan)] |
Full Idea: Of those ignorant of the Self (Atman), some enter into beings possessed of wombs, others enter into plants - according to their deeds and the growth of their intelligence. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Katha') | |
A reaction: "I sigh and sigh, and wish I were a tree" wrote George Herbert. You probably need the snobbery of the Indian caste system to appreciate the horrors of low rebirth. I quite fancy being a dolphin, but a tulip would be all right. |
8149 | Charity and ritual observance distract from the highest good of religion [Anon (Upan)] |
Full Idea: Considering religion to be observance of rituals and performance of acts of charity, the deluded remain ignorant of the highest good. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Mundaka') | |
A reaction: An important reminder. In all the great religious texts the exhortation to love and charity is a minor aspect. The point is to live on a spiritual plain, attempting to relate the world of God/the gods. Daily life is either secondary or irrelevant. |
8158 | Do not seek to know Brahman by arguments, for arguments are idle and vain [Anon (Upan)] |
Full Idea: Do not seek to know Brahman by arguments, for arguments are idle and vain. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Brihadaranyaka') | |
A reaction: In the end all the religions seem to gravitate towards fideism and away from reasoned argument. The Catholic Church may be the last bastion of rational theology. Islam (10th cent), Protestantism (16th) and Judaism (17th) all rejected philosophy. |
8146 | The immortal in us is the part that never sleeps, and shapes our dreams [Anon (Upan)] |
Full Idea: That which is awake in us even while we sleep, shaping in dream the objects of our desire - that indeed is pure, that is Brahman, and that verily is called the Immortal. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Katha') | |
A reaction: That is a more helpful view of what the soul might be than anything found in Christian theology. It makes it the essence of the everyday Self. It is left with the difficulty of lacking individuality, and being of limited interest to my wider Self. |
8150 | The immortal Self and the sad individual self are like two golden birds perched on one tree [Anon (Upan)] |
Full Idea: Like two birds of golden plumage, the individual self and the immortal Self perch on the branches of the same tree. The individual self, deluded by forgetfulness of his identity with the divine self, bewildered by his ego, grieves and is sad. | |
From: Anon (Upan) (The Upanishads [c.950 BCE], 'Mundaka') | |
A reaction: Hinduism gives a much clearer and bolder picture of the soul than Christianity does. I don't see much consolation in the immortality of the wonderful Self, if my individual self is doomed to misery and extinction. Which one is me? |
