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. |
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) |
15785 | Our commitments are to an 'ontology', but also to an 'ideology', or conceptual system [Hintikka] |
Full Idea: We must distinguish between what we are committed to existing in the actual world or a possible world ('ontology'), and what we are committed to as a part of our ways of dealing with the world conceptually, as a part of our conceptual system ('ideology'). | |
From: Jaakko Hintikka (Semantics for Propositional Attitudes [1969], p.95), quoted by William Lycan - The Trouble with Possible Worlds 02 | |
A reaction: I think this is the most illuminating idea I have read on the subject of ontological commitment. I'm fighting for the idea that what we think is true should be kept separate from what we think exists. Ideology is a nice addition to the mix. |
15786 | Commitment to possible worlds is part of our ideology, not part of our ontology [Hintikka] |
Full Idea: Quantification over members of one particular world is a measure of ideology, quantification that crosses possible worlds is often a measure of ideology. | |
From: Jaakko Hintikka (Semantics for Propositional Attitudes [1969], p.95), quoted by William Lycan - The Trouble with Possible Worlds 02 | |
A reaction: I like this. See Idea 15785 for the underlying distinction. It leaves the question open of what we might mean by 'ideological commitment'. |
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) |
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) |
6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
Full Idea: Hermarchus said that animal killing is justified by considerations of human safety and nourishment and by animals' inability to form contractual relations of justice with us. | |
From: report of Hermarchus (fragments/reports [c.270 BCE]) by David A. Sedley - Hermarchus | |
A reaction: Could the last argument be used to justify torturing animals? Or could we eat a human who was too brain-damaged to form contracts? |
