3067 | A philosopher should have principles ready for understanding, like a surgeon with instruments [Aurelius] |
Full Idea: As physicians have always their instruments and knives ready for cases which suddenly require their skill, so should you have principles ready for the understanding of things divine and human. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 3.13) | |
A reaction: Nice. Philosophy is the training ground where wisdom and good living are made possible, but it cannot be a substitute for living. |
7662 | Romanticism is the greatest change in the consciousness of the West [Berlin] |
Full Idea: Romanticism seems to me the greatest single shift in the consciousness of the West that has occurred. | |
From: Isaiah Berlin (The Roots of Romanticism [1965], Ch.1) | |
A reaction: Far be it from me to challenge Berlin on such things, but I think that the scientific revolution of the seventeenth century (though acting more slowly and less dramatically than romanticism) may well be more significant in the long run. Ideas filter down. |
11211 | If a sound conclusion comes from two errors that cancel out, the path of the argument must matter [Rumfitt] |
Full Idea: If a designated conclusion follows from the premisses, but the argument involves two howlers which cancel each other out, then the moral is that the path an argument takes from premisses to conclusion does matter to its logical evaluation. | |
From: Ian Rumfitt ("Yes" and "No" [2000], II) | |
A reaction: The drift of this is that our view of logic should be a little closer to the reasoning of ordinary language, and we should rely a little less on purely formal accounts. |
11210 | Standardly 'and' and 'but' are held to have the same sense by having the same truth table [Rumfitt] |
Full Idea: If 'and' and 'but' really are alike in sense, in what might that likeness consist? Some philosophers of classical logic will reply that they share a sense by virtue of sharing a truth table. | |
From: Ian Rumfitt ("Yes" and "No" [2000]) | |
A reaction: This is the standard view which Rumfitt sets out to challenge. |
11212 | The sense of a connective comes from primitively obvious rules of inference [Rumfitt] |
Full Idea: A connective will possess the sense that it has by virtue of its competent users' finding certain rules of inference involving it to be primitively obvious. | |
From: Ian Rumfitt ("Yes" and "No" [2000], III) | |
A reaction: Rumfitt cites Peacocke as endorsing this view, which characterises the logical connectives by their rules of usage rather than by their pure semantic value. |
3072 | Everything is changing, including yourself and the whole universe [Aurelius] |
Full Idea: All things are changing; and you yourself are in continuous mutation and in a manner in continuous destruction, and the whole universe too. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 9.19) |
11214 | We learn 'not' along with affirmation, by learning to either affirm or deny a sentence [Rumfitt] |
Full Idea: The standard view is that affirming not-A is more complex than affirming the atomic sentence A itself, with the latter determining its sense. But we could learn 'not' directly, by learning at once how to either affirm A or reject A. | |
From: Ian Rumfitt ("Yes" and "No" [2000], IV) | |
A reaction: [compressed] This seems fairly anti-Fregean in spirit, because it looks at the psychology of how we learn 'not' as a way of clarifying what we mean by it, rather than just looking at its logical behaviour (and thus giving it a secondary role). |
7665 | Most Enlightenment thinkers believed that virtue consists ultimately in knowledge [Berlin] |
Full Idea: What is common to most of the main thinker of the Enlightenment is the view that virtue consists ultimately in knowledge. | |
From: Isaiah Berlin (The Roots of Romanticism [1965], Ch.2) | |
A reaction: I have always found this view (which seems to originate with Socrates) rather sympathetic. What is so frustrating about cheerful optimists who smoke cigarettes is not the weakness of will or strong desires, but their apparent failure of understanding. |
3066 | Nothing is evil which is according to nature [Aurelius] |
Full Idea: Nothing is evil which is according to nature. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 2.17) | |
A reaction: A bit hopeful. Sounds tautological. I.e. anything which is agreed to be evil is probably immediately labelled as 'unnatural'. What would he agree was evil? |
3071 | Justice has no virtue opposed to it, but pleasure has temperance opposed to it [Aurelius] |
Full Idea: In the constitution of the rational animal I see no virtue which is opposed to justice; but I see a virtue which is opposed to pleasure, and that is temperance. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 8.39) | |
A reaction: There are plenty of hideous things opposed to justice, but presumably that immediately disqualifies them from being virtues. |
3069 | The art of life is more like the wrestler's than the dancer's [Aurelius] |
Full Idea: The art of life is more like the wrestler's than the dancer's. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 7.61) |
7676 | If we are essentially free wills, authenticity and sincerity are the highest virtues [Berlin] |
Full Idea: Since (for romantics) we are wills, and we must be free, in the Kantian sense, controllable motives count more than consequences, and the greatest virtue of all is what existentialists call 'authenticity' and what romantics called 'sincerity'. | |
From: Isaiah Berlin (The Roots of Romanticism [1965], Ch.6) | |
A reaction: The case of the sincere or authentic Nazi shows the problems with this. However, I agree that sincerity is a key virtue, perhaps the crucial preliminary to all the other virtues. It is hard to imagine a flow of other virtues from an insincere person. |
7664 | The Greeks have no notion of obligation or duty [Berlin] |
Full Idea: There is an absence among the Greeks of a notion of obligation, and hence of duty, which is difficult to grasp for people who read the Greeks through spectacles partly affected by the jews. | |
From: Isaiah Berlin (The Roots of Romanticism [1965], Ch.1) | |
A reaction: This doesn't quite fit early section of 'Republic', in which morality is a mutual agreement not to do harm. Presumably the Greek word 'deon' refers to what needs to be done, rather than to anyone's obligation to do it(?). Contracts need duty? Cf. 4133 |
7677 | Central to existentialism is the romantic idea that there is nothing to lean on [Berlin] |
Full Idea: The central sermon of existentialism is essentially a romantic one, namely, that there is in the world nothing to lean on. | |
From: Isaiah Berlin (The Roots of Romanticism [1965], Ch.6) | |
A reaction: He tracks this back to Kant's view that our knowledge of the world arises out of our own minds. So what is there to lean on? Rational consistency? Natural human excellence? God? Pleasure? Anonymous duty? I like the second one. |
3065 | Humans are naturally made for co-operation [Aurelius] |
Full Idea: We are made for cooperation, like feet, like hands, like eyelids, like the rows of upper and lower teeth. To act against one another, then, is contrary to nature. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 2.1) |
7663 | Judaism and Christianity views are based on paternal, family and tribal relations [Berlin] |
Full Idea: The notion from which both Judaism and Christianity to a large degree sprang is the notion of family life, the relations of father and son, perhaps the relations of members of a tribe to one another. | |
From: Isaiah Berlin (The Roots of Romanticism [1965], Ch.1) | |
A reaction: He compares this with Plato's mathematical view of reality. Key stories would be Abraham and Isaac, and Jesus being the 'son' of God, which both touch the killing of the child. Berlin means that the universe is explained this way. |
