10 ideas
| 23367 | Even pointing a finger should only be done for a reason [Epictetus] |
| Full Idea: Philosophy says it is not right even to stretch out a finger without some reason. | |
| From: Epictetus (fragments/reports [c.57], 15) | |
| A reaction: The key point here is that philosophy concerns action, an idea on which Epictetus is very keen. He rather despise theory. This idea perfectly sums up the concept of the wholly rational life (which no rational person would actually want to live!). |
| 14767 | The demonstrations of the metaphysicians are all moonshine [Peirce] |
| Full Idea: The demonstrations of the metaphysicians are all moonshine. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.2) |
| 14764 | I am saturated with the spirit of physical science [Peirce] |
| Full Idea: I am saturated, through and through, with the spirit of the physical sciences. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.1) |
| 14768 | Infallibility in science is just a joke [Peirce] |
| Full Idea: Infallibility in scientific matters seems to me irresistibly comical. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.3) |
| 14765 | Association of ideas is the best philosophical idea of the prescientific age [Peirce] |
| Full Idea: The doctrine of the association of ideas is, to my thinking, the finest piece of philosophical work of the prescientific ages. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.2) |
| 14766 | Duns Scotus offers perhaps the best logic and metaphysics for modern physical science [Peirce] |
| Full Idea: The works of Duns Scotus have strongly influenced me. …His logic and metaphysics, torn away from its medievalism, …will go far toward supplying the philosophy which is best to harmonize with physical science. | |
| From: Charles Sanders Peirce (Concerning the Author [1897], p.2) |
| 23111 | If we say that freedom depends on rationality, the irrational actions are not free [Sidgwick] |
| Full Idea: If we say that a man is a free agent in proportion as he acts rationally, we cannot also say that it is by free choice that he acts irrationally. | |
| From: Henry Sidgwick (The Methods of Ethics (7th edn) [1874], p.511), quoted by John Kekes - Against Liberalism 7.4 | |
| A reaction: A very nice riposte. Clearly people can rationally choose to act irrationally, e.g. at a wild party. |
| 23059 | Self-interest is not rational, if the self is just a succession of memories and behaviour [Sidgwick, by Gray] |
| Full Idea: Sidgwick said self-interest is not self-evidently rational. Unless we invoke a religious idea of the soul, human personality is no more than a succession of continuities in memory and behaviour. In that case, why should anyone favour their future self? | |
| From: report of Henry Sidgwick (The Methods of Ethics (7th edn) [1874]) by John Gray - Seven Types of Atheism 2 | |
| A reaction: This sounds like Locke's account of the self, as psychological continuity. We can say that our continuous self is a fiction, the hero of our own narrative. Personally I think of the self as a sustained set of brains structures which change very little. |
| 4129 | It is self-evident (from the point of view of the Universe) that no individual has more importance than another [Sidgwick] |
| Full Idea: It is a self-evident principle that the good of one individual is of no more importance, from the point of view of the Universe, than the good of any other, ..and as a rational being I am bound to aim at good generally, not merely at a particular part. | |
| From: Henry Sidgwick (The Methods of Ethics (7th edn) [1874], III.XIII.3) | |
| A reaction: Showing that even a very empirical theory like utilitarianism has an a priori basis. Of course, the principle is false. What about animals, the senile, criminals, androids? What bestows 'importance'? |
| 20588 | Sidwick argues for utilitarian institutions, rather than actions [Sidgwick, by Tuckness/Wolf] |
| Full Idea: Sidgwick's complex version of utilitarianism urges that institutions should be set in place to maximise utility, but that individual actions people undertake might not appear to be justifiable on utilitarian terms. | |
| From: report of Henry Sidgwick (The Methods of Ethics (7th edn) [1874]) by Tuckness,A/Wolf,C - This is Political Philosophy 1 Refs | |
| A reaction: This seems to be a specifically political version of utilitarianism, but isn't cited much by political philosophers who discuss utilitarianism. |
