14 ideas

1. Philosophy / A. Wisdom / 2. Wise People
A wise man is not subservient to anything [Seneca]
     Full Idea: I do not call any man wise who is subservient to anything.
     From: Seneca the Younger (On the Happy Life [c.60], §11)
     A reaction: At the very least, a wise man should be subservient to a wiser man.
1. Philosophy / C. History of Philosophy / 4. Later European Philosophy / b. Seventeenth century philosophy
Most philosophers start with reality and then examine knowledge; Descartes put the study of knowledge first [Lehrer]
     Full Idea: Some philosophers (e.g Plato) begin with an account of reality, and then appended an account of how we can know it, ..but Descartes turned the tables, insisting that we must first decide what we can know.
     From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.2)
1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
You cannot demand an analysis of a concept without knowing the purpose of the analysis [Lehrer]
     Full Idea: An analysis is always relative to some objective. It makes no sense to simply demand an analysis of goodness, knowledge, beauty or truth, without some indication of the purpose of the analysis.
     From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.7)
     A reaction: Your dismantling of a car will go better if you know what a car is for, but you can still take it apart in ignorance.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / a. Idealistic ethics
The supreme good is harmony of spirit [Seneca]
     Full Idea: The highest good is harmony of spirit.
     From: Seneca the Younger (On the Happy Life [c.60], §08)
     A reaction: This idea is straight from Plato's Republic.
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / c. Motivation for virtue
I seek virtue, because it is its own reward [Seneca]
     Full Idea: You ask what I seek from virtue? Virtue herself. For she has nothing better, she is herself her own reward.
     From: Seneca the Younger (On the Happy Life [c.60], §09)
     A reaction: Presumably this is the source of the popular saying that 'virtue is its own reward'. The trouble is that this doesn't seem a very persuasive thing to say to a sceptic who doubts whether being virtuous is worth the trouble.
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / j. Unity of virtue
Virtue is always moderate, so excess need not be feared [Seneca]
     Full Idea: In the case of virtue excess should not be feared, since in virtue resides moderation.
     From: Seneca the Younger (On the Happy Life [c.60], §13)
     A reaction: This seems to imply that all of the virtues are unified in the one achievement of the virtuous state. It leaves the notion of 'virtue' a bit thin in content, though.
23. Ethics / C. Virtue Theory / 3. Virtues / a. Virtues
It is shameful to not even recognise your own slaves [Seneca]
     Full Idea: Why, to your shame, are you so careless that you do not know your handful of slaves by sight?
     From: Seneca the Younger (On the Happy Life [c.60], §17)
23. Ethics / C. Virtue Theory / 4. External Goods / c. Wealth
Why does your wife wear in her ears the income of a wealthy house? [Seneca]
     Full Idea: Why does your wife wear in her ears the income of a wealthy house?
     From: Seneca the Younger (On the Happy Life [c.60], §17)
If wealth was a good, it would make men good [Seneca]
     Full Idea: Wealth is not a good; for it it was, it would make men good.
     From: Seneca the Younger (On the Happy Life [c.60], §24)
     A reaction: An immediately attractive argument, but should we assume that anything which is good will enhance our personal goodness? If goodness is a habit, then continual pursuit of wealth is the test case to examine. Seneca is right!
There is far more scope for virtue if you are wealthy; poverty only allows endurance [Seneca]
     Full Idea: What doubt can there be that the wise man has greater scope for displaying his powers if he is rich than if he is poor, since in the case of poverty only one kind of virtue exists - refusal to be bowed down and crushed.
     From: Seneca the Younger (On the Happy Life [c.60], §22)
     A reaction: It is against this view that I see Jesus proposing poverty as central to virtue. But then he has the surprising view (to Seneca) that humility is a virtue. What Nietzsche calls the slaves' inversion of values.
24. Political Theory / D. Ideologies / 5. Democracy / f. Against democracy
Unfortunately the majority do not tend to favour what is best [Seneca]
     Full Idea: Human concerns are not so happily arranged that the majority favours the better things.
     From: Seneca the Younger (On the Happy Life [c.60], §02)
     A reaction: On the whole Seneca is unimpressed by democracy, as people are rushed into decisions by the crowd, and live to regret them.
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / b. Fields
Fields can be 'scalar', or 'vector', or 'tensor', or 'spinor' [Baggott]
     Full Idea: Fields can be 'scalar', with no particular direction (pointing, but not pushing or pulling); or 'vector', with a direction (like magnetism, or Newtonian gravity); or 'tensor' (needing further parameters); or 'spinor' (depending on spin orientation).
     From: Jim Baggott (Farewell to Reality: fairytale physics [2013], 2 'Quantum')
     A reaction: [compressed] So the question is, why do they differ? What is it in the nature of each field the result in a distinctive directional feature?
A 'field' is a property with a magnitude, distributed across all of space and time [Baggott]
     Full Idea: A 'field' is defined in terms of the magnitude of some physical property distributed over every point in time and space.
     From: Jim Baggott (Farewell to Reality: fairytale physics [2013], 2 'Quantum')
     A reaction: If it involves a 'property', normal usage entails that there is some entity which possesses the property. So what's the entity? Eh? Eh? You don't know! Disappointed...
27. Natural Reality / B. Modern Physics / 4. Standard Model / b. Standard model
The current standard model requires 61 particles [Baggott]
     Full Idea: The current model requires 61 particles: three generations of two leptons and two flavours of quark, in three different colours (making 24); the anti-particles of all of these (48); 12 force particles (photon, W1, Z0, 8 gluons), and a Higgs boson.
     From: Jim Baggott (Farewell to Reality: fairytale physics [2013], 6 n)
