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) |
22137 | Observation can force rejection of some part of the initial set of claims [Duhem, by Boulter] |
Full Idea: Logic and observation alone do not force a scientist to reject a scientific claim if experimental observations so not turn out as expected. The scientist must reject something of the initial set of claims, but that is a matter of choice. | |
From: report of Pierre Duhem (The Aim and Structure of Physical Theory [1906]) by Stephen Boulter - Why Medieval Philosophy Matters 2 | |
A reaction: This is a key point against any simplified Popperian notion of falsification. Tiny observations can't kill huge well supported theories. |
18197 | Experiments only test groups of hypotheses, and can't show which one is wrong [Duhem] |
Full Idea: The physicist can never subject an isolated hypothesis to experimental test, but only a whole group of hypotheses; when the experiment is in disagreement with his predictions ...it does not designate which one should be changed. | |
From: Pierre Duhem (The Aim and Structure of Physical Theory [1906], p.187), quoted by Penelope Maddy - Naturalism in Mathematics II.2 | |
A reaction: This is the idea frequently invoked by Quine, in support of his holistic view of scientific knowledge (along with Neurath's Boat). |
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) |
7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom. | |
From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88) | |
A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate'). |
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) |
