1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / a. Philosophy as worldly
Ideals and metaphysics are practical, not imaginative or speculative [Green,TH, by Muirhead]
     Full Idea: To T.H. Green an ideal was no creation of an idle imagination, metaphysics no mere play of the speculative reason. Ideals were the most solid, and metaphysics the most practical thing about a man.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State I
     A reaction: This is despite the fact that Green was an idealist in the Hegelian tradition. I like this. I see it not just as ideals having practical guiding influence, but also that ideals themselves arising out of experience.
1. Philosophy / G. Scientific Philosophy / 1. Aims of Science
Science is in the business of carving nature at the joints [Segal]
     Full Idea: Science is in the business of carving nature at the joints.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 5)
2. Reason / A. Nature of Reason / 8. Naturalising Reason
Psychology studies the way rationality links desires and beliefs to causality [Segal]
     Full Idea: A person's desires and beliefs tend to cause what they tend to rationalise. This coordination of causality and rationalisation lies at the heart of psychology.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 5.3)
3. Truth / D. Coherence Truth / 1. Coherence Truth
Truth is a relation to a whole of organised knowledge in the collection of rational minds [Green,TH, by Muirhead]
     Full Idea: When we speak of anything as true or false, we do so on the ground of its relation to a whole of organised knowledge existing actually in no human mind, but prefigured in every mind which is possessed of reason.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State I n1
     A reaction: This seems to be the super-idealist view of the coherence account of truth. I have no idea what 'prefigured' means here.
10. Modality / A. Necessity / 5. Metaphysical Necessity
Is 'Hesperus = Phosphorus' metaphysically necessary, but not logically or epistemologically necessary? [Segal]
     Full Idea: It is metaphysically necessary that Hesperus is Phosphorus, but not logically necessary, since logical deduction could not reveal its truth, and it is not epistemologically necessary, as the ancient Greeks didn't know the identity. (Natural necessity?)
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 1.6)
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / b. Conceivable but impossible
If claims of metaphysical necessity are based on conceivability, we should be cautious [Segal]
     Full Idea: Since conceivability is the chief method of assessing the claims of metaphysical necessity, I think such claims are incautious.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 1.6)
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / d. Absolute idealism
All knowledge rests on a fundamental unity between the knower and what is known [Green,TH, by Muirhead]
     Full Idea: All knowledge is seen on ultimate analysis to rest upon the idea of a fundamental unity between subject and object, between the knower and that which there is to be known.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State III
     A reaction: I don't really understand this thought, but I think it embodies the essence of Hegelian idealism. If I know a tree in the wood, any 'unity' between us strikes as merely imaginary. If the tree isn't separate, what does 'knowing' it mean?
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / a. Coherence as justification
The ultimate test for truth is the systematic interdependence in nature [Green,TH, by Muirhead]
     Full Idea: Systematic interdependence in the world of nature is the ultimate test of truth.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State II
     A reaction: Green (or Muirhead) drifts between coherence as the nature of truth and coherence as the nature of justification. He it is the 'test' for truth, which was Russell's view.
Knowledge is secured by the relations between its parts, through differences and identities [Green,TH, by Muirhead]
     Full Idea: What gives reality and stability to our knowledge is the reality and stability of the relations established between its parts..…by the differences and identities with other things which have similarly achieved comparative fixity and substantiality.
     From: report of T.H. Green (Lectures on the Principles of Political Obligation [1882]) by John H. Muirhead - The Service of the State I
     A reaction: Although I don't sympathise with Green's idealist metaphysics, and nevertheless think that this internalist account of knowledge is correct.
14. Science / D. Explanation / 3. Best Explanation / c. Against best explanation
The success and virtue of an explanation do not guarantee its truth [Segal]
     Full Idea: The success and virtue of an explanation do not guarantee its truth.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 2.2)
18. Thought / A. Modes of Thought / 4. Folk Psychology
Folk psychology is ridiculously dualist in its assumptions [Segal]
     Full Idea: Commonsense psychology is a powerful explanatory theory, and largely correct, but it seems to be profoundly dualist, and treats minds as immaterial spirits which can transmigrate and exist disembodied.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 2.2)
     A reaction: Fans of folk psychology tend to focus on central normal experience, but folk psychology also seems to range from quirky to barking mad. A 'premonition' is a widely accepted mental event.
18. Thought / C. Content / 5. Twin Earth
If 'water' has narrow content, it refers to both H2O and XYZ [Segal]
     Full Idea: My view is that the concepts of both the Earth person and the Twin Earth person refer to BOTH forms of diamonds or water (H2O and XYZ).
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 1.7)
     A reaction: Fair enough, though that seems to imply that my current concepts may actually refer to all sorts of items of which I am currently unaware. But that may be so.
Humans are made of H2O, so 'twins' aren't actually feasible [Segal]
     Full Idea: Humans are largely made of H2O, so there could be no twin on Twin Earth, and (as Kuhn noted) nothing with a significantly different structure from H2O could be macroscopically very like water (but topaz and citrine will do).
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 2.1)
     A reaction: A small point, but one that appeals to essentialists like me (see under Natural Theory/Laws of Nature). We can't learn much metaphysics from impossible examples.
Externalists can't assume old words refer to modern natural kinds [Segal]
     Full Idea: The question of what a pre-scientific term extends over is extremely difficult for a Putnam-style externalist to answer. …There seems no good reason to assume that they extend over natural kinds ('whale', 'cat', 'water').
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 5.1)
     A reaction: The assumption seems to be that they used to extend over descriptions, and now they extend over essences, or expert references. This can't be right. They have never changed, but now contain fewer errors.
18. Thought / C. Content / 6. Broad Content
Externalism can't explain concepts that have no reference [Segal]
     Full Idea: Empty terms and concepts provide the largest problem for the externalist thesis of the world dependence of concepts.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 2.2)
     A reaction: A speculative concept could then become a reality (e.g. an invention). The solution seems to be to say that there is an internal and an external component to most concepts.
If content is external, so are beliefs and desires [Segal]
     Full Idea: If we accept Putnam's externalist conclusion about the meaning of a word, it is a short step to a similar conclusion about the contents of the twins' beliefs, desires and so on.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 2.1)
     A reaction: This is the key step which has launched a whole new externalist view of the nature of the mind. It is one thing to say that I don't quite know what my words mean, another that I don't know my own beliefs.
Must we relate to some diamonds to understand them? [Segal]
     Full Idea: Is a relationship with diamonds necessary for having a concept of diamonds?
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 1.4)
     A reaction: Probably not, given that I have a concept of kryptonite, and that I can invent my own concepts. Suppose I was brought up to believe that diamonds are a myth?
Maybe experts fix content, not ordinary users [Segal]
     Full Idea: Putnam and Burge claim that there could be two words that a misinformed subject uses to express different concepts, but that express just one concept of the experts.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 3.2)
     A reaction: This pushes the concept outside the mind of the user, which leaves an ontological problem of what concepts are made of, how you individuate them, and where they are located.
Concepts can survive a big change in extension [Segal]
     Full Idea: We need to think of concepts as organic entities that can persist through changes of extension.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 3.3)
     A reaction: This would be 'organic' in the sense of modifying and growing. This is exactly right, and the interesting problem becomes the extreme cases, where an individual stretches a concept a long way.
Maybe content involves relations to a language community [Segal]
     Full Idea: It has been argued (e.g. by Tyler Burge) that certain relations to other language users are determinants of content.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 1.4)
     A reaction: Burge's idea (with Wittgenstein behind him) strikes me as plausible (more plausible than water and elms determining the content). Our concepts actually shift during conversations.
18. Thought / C. Content / 7. Narrow Content
If content is narrow, my perfect twin shares my concepts [Segal]
     Full Idea: To say that contents of my belief are narrow is to say that they are intrinsic to me, hence that any perfect twin of mine would have beliefs with the same contents.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 5)
     A reaction: I personally find this more congenial than externalism. If my twin and I studied chemistry, we would reach identical conclusions about water, as long as we remained perfect twins.
18. Thought / C. Content / 10. Causal Semantics
If thoughts ARE causal, we can't explain how they cause things [Segal]
     Full Idea: If we identify a psychological property with its causal role then we lose the obvious explanation of why the event has the causal role that it has.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 4.1)
     A reaction: This pinpoints very nicely one of the biggest errors in modern philosophy. There are good naturalistic reasons to reduce everything to causal role, but there is a deeper layer. Essences!
Even 'mass' cannot be defined in causal terms [Segal]
     Full Idea: We can't define mass in terms of its causal powers because massive objects do different things in different physical systems. …What an object (or concept) with a given property does depends on what it interacts with.
     From: Gabriel M.A. Segal (A Slim Book about Narrow Content [2000], 4.1)
     A reaction: This leaves an epistemological problem, that we believe in mass, but can only get at it within a particular gravitational or inertial system. Don't give up on ontology at this point.
19. Language / B. Reference / 1. Reference theories
The Electra: she knows this man, but not that he is her brother [Eucleides, by Diog. Laertius]
     Full Idea: The 'Electra': Electra knows that Orestes is her brother, but not that this man is Orestes, so she knows and does not know her brother simultaneously.
     From: report of Eucleides (fragments/reports [c.410 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Eu.4
     A reaction: Hence we distinguish 'know of', 'know that' and 'know how'. Hence Russell makes 'knowledge by acquaintance' fundamental, and descriptions come later.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / a. Idealistic ethics
The good life aims at perfections, or absolute laws, or what is absolutely desirable [Green,TH]
     Full Idea: The differentia of the good life …is controlled by the consciousness of there being some perfection which has to be fulfilled, some law which has to be obeyed, something absolutely desirable whatever the individual may for the time desire.
     From: T.H. Green (Prolegomena to Ethics [1882], p.134), quoted by John H. Muirhead - The Service of the State II
     A reaction: The 'perfection' suggests Plato, and the 'law' suggests Kant. The idea that something is 'absolutely desirable' is, I suspect, aimed at the utilitarians, who don't care what is desired. I'm no idealist, but have some sympathy with this idea.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
What is distinctive of human life is the desire for self-improvement [Green,TH, by Muirhead]
     Full Idea: All that is distinctively human in the life of man springs not from the desire to possess this or that object, and so far to realise a better, but to be something more and better than he is.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State II
     A reaction: An example of Victorian optimism, I think. I'm guessing that people who are not motivated by this impulse are not behaving in a way that is 'distinctively human'. That said, this is an interesting aspect of human nature.
22. Metaethics / C. The Good / 1. Goodness / b. Types of good
The chief good is unity, sometimes seen as prudence, or God, or intellect [Eucleides]
     Full Idea: The chief good is unity, which is known by several names, for at one time people call it prudence, at another time God, at another intellect, and so on.
     From: Eucleides (fragments/reports [c.410 BCE]), quoted by Diogenes Laertius - Lives of Eminent Philosophers 02.9.2
     A reaction: So the chief good is what unites and focuses our moral actions. Kant calls that 'the will'.
23. Ethics / A. Egoism / 2. Hedonism
Hedonism offers no satisfaction, because what we desire is self-betterment [Green,TH, by Muirhead]
     Full Idea: Hedonism failed because it offered as an end of human aspiration an object in which the human spirit, pledged by its own nature to self-betterment, …could never find satisfaction.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State II
     A reaction: It is always both sad and amusing to see that 150 years ago someone wrote of a doctrine that is still with us that it has 'failed'. Nowadays they try to say the same of physicalism. His objection rests on optimism about humanity.
24. Political Theory / B. Nature of a State / 2. State Legitimacy / a. Sovereignty
States only have full authority if they heed the claims of human fellowship [Green,TH]
     Full Idea: The claim of the state is only absolutely paramount on the supposition that in its commands and prohibitions it takes account of all the claims that arise out of human fellowship.
     From: T.H. Green (Lectures on the Principles of Political Obligation [1882], §146), quoted by John H. Muirhead - The Service of the State III
     A reaction: He rejects the idea of the general will in ordinary political activity, so it is not clear how this condition could ever be met in practice. Hideous governments just pay lip service to 'human fellowship'. How could you tell whether they believe it?
24. Political Theory / B. Nature of a State / 2. State Legitimacy / d. General will
Politics is compromises, which seem supported by a social contract, but express the will of no one [Green,TH]
     Full Idea: Where laws and institutions are apparently the work of deliberate volition, they are in reality the result of a compromise, which while by a kind of social contract it has the acquiescence of all, expresses the will of none.
     From: T.H. Green (works [1875]), quoted by John H. Muirhead - The Service of the State III
     A reaction: Politicians who claim to be enacting the 'will of the people' (e.g. when they won a referendum 52-48) are simply lying. Committees usually end up enacting one person's will, but often without realising what has happened.
24. Political Theory / B. Nature of a State / 4. Citizenship
The ideal is a society in which all citizens are ladies and gentlemen [Green,TH]
     Full Idea: With all seriousness and reverence we may hope and pray for a condition of English society in which all honest citizens will recognise themselves and be recognised by each other as gentlemen.
     From: T.H. Green (works [1875]), quoted by John H. Muirhead - The Service of the State IV
     A reaction: Call me old fashioned but, as long as we expand this to include ladies, I like this thought. Chaucer's knight (in his Prologue) should be our national role model. The true gentleman is an Aristotelian ideal.
Enfranchisement is an end in itself; it makes a person moral, and gives a basis for respect [Green,TH]
     Full Idea: Enfranchisement of the people is an end in itself. …Only citizenship makes the moral man; only citizenship gives that respect which is the true basis of the respect for others.
     From: T.H. Green (works [1875], iii:436), quoted by John H. Muirhead - The Service of the State IV
     A reaction: Should people respect their betters? If so, that is a sort of deferential respect which is different from the mutual respect between equals. That said, I wholly approve of this idea.
24. Political Theory / D. Ideologies / 6. Liberalism / a. Liberalism basics
The good is identified by the capacities of its participants [Green,TH, by Muirhead]
     Full Idea: The modern idea of the good has developed in respect of the range of persons who have the capacity and therefore the right to participate in this good.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State II
     A reaction: Green is a notable Victorian liberal, starting from an idealist metaphysics. This is an intriguing view of liberal values. The concept of the good should be what suits persons with full capacity. Having the capacity bestows the right of access to it. Hm.
24. Political Theory / D. Ideologies / 6. Liberalism / b. Liberal individualism
A true state is only unified and stabilised by acknowledging individuality [Green,TH, by Muirhead]
     Full Idea: In so far as society commits itself to the principle of individuality of its citizens does it realise the unity and stability that constitute it a true 'State'.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State II
     A reaction: This asserts the liberal vision of a state, rather than asserting a fact. A state consistently mostly of slaves still seems to be a state, and may achieve a lot.
24. Political Theory / D. Ideologies / 6. Liberalism / c. Liberal equality
People are improved by egalitarian institutions and habits [Green,TH]
     Full Idea: Man has bettered himself through institutions and habits which tend to make the welfare of all the welfare of each.
     From: T.H. Green (Prolegomena to Ethics [1882], p.180), quoted by John H. Muirhead - The Service of the State II
     A reaction: I like this a lot. We underestimate how the best social values are promoted by the existence of enlightened institutions, rather than by preaching and teaching. Schools, law courts and churche embody their values.
24. Political Theory / D. Ideologies / 6. Liberalism / d. Liberal freedom
Equality also implies liberty, because equality must be of opportunity as well as possessions [Green,TH]
     Full Idea: Liberty was essential, not only as a means to equality, but as part of it. …because the opportunity which was to be equalised was not merely to have and to be happy, but to do and to realise. It was 'the right of man to make the best of himself'.
     From: T.H. Green (Lectures on the Principles of Political Obligation [1882]), quoted by John H. Muirhead - The Service of the State IV
     A reaction: This nicely identifies the core idea of civilised liberalism (as opposed to the crazy self-seeking kind). I think 'give people the right to make the best of themselves' makes a good slogan, because it implies ensuring that they have the means.
24. Political Theory / D. Ideologies / 6. Liberalism / e. Liberal community
All talk of the progress of a nation must reduce to the progress of its individual members [Green,TH]
     Full Idea: Our ultimate standard of worth is an ideal of personal worth. All other values are relative to personal values. To speak of any progress of a nation or society or mankind except as relative to some greater worth of persons is to use words without meaning.
     From: T.H. Green (Prolegomena to Ethics [1882], p.193), quoted by John H. Muirhead - The Service of the State II
     A reaction: Note that, pre-verificationism, a Victorian talks of plausible words actually being meaningless. This is a good statement of the core doctrine of liberalism.
24. Political Theory / D. Ideologies / 7. Communitarianism / a. Communitarianism
People only develop their personality through co-operation with the social whole [Green,TH, by Muirhead]
     Full Idea: In so far as the individual commits himself to the principle of co-operation in a social whole does he realise his end as individual personality.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State II
     A reaction: This makes for a very communitarian type of liberalism. The question is whether we create insitutions which suck our free citizens into a communal way of life, or whether that is a matter of their own initiative.
The highest political efforts express our deeper social spirit [Green,TH, by Muirhead]
     Full Idea: Political effort in all its highest forms is the expression of a belief in the reality of the social spirit as the deeper element in the individual.
     From: report of T.H. Green (Lectures on the Principles of Political Obligation [1882]) by John H. Muirhead - The Service of the State I
     A reaction: Although Green is rather literally spiritual, if we express it as a central aspect of human nature, this idea strikes me as correct. Writing in 2021, I am totally bewildered by the entire absence of any 'higher' forms of political expression.
24. Political Theory / D. Ideologies / 9. Communism
Communism is wrong because it restricts the freedom of individuals to contribute to the community [Green,TH, by Muirhead]
     Full Idea: Green condemned pure communism, not in the name of any abstract rights of the individual, but of the right of the community itself to the best that individuals can contribute through the free and spontaneous exercise of their powers of self-expression.
     From: report of T.H. Green (Lectures on the Principles of Political Obligation [1882]) by John H. Muirhead - The Service of the State IV
     A reaction: Interesting. In a very authoritarian communist state it does seem that citizens are less able to contribute to the general good. But extreme liberty seems also to undermine the general good. Hm.
Original common ownership is securing private property, not denying it [Green,TH, by Muirhead]
     Full Idea: Common ownership in early societies is not the denial of a man's private property in the products of his own labour, but the only way under the circumstances of securing it.
     From: report of T.H. Green (Lectures on the Principles of Political Obligation [1882], §218) by John H. Muirhead - The Service of the State III
     A reaction: This is announced with some confidence, but it is very speculative. I think there is some truth in Locke's thought that putting work into a creation creates natural ownership. But who owns the raw materials? Why is work valued highly?
24. Political Theory / D. Ideologies / 14. Nationalism
National spirit only exists in the individuals who embody it [Green,TH, by Muirhead]
     Full Idea: A national spirit cannot exist apart from the individuals who embody it.
     From: report of T.H. Green (Lectures on the Principles of Political Obligation [1882]) by John H. Muirhead - The Service of the State II
     A reaction: We see this in football supporters. They are thrilled by the glory of a great victory, but the reality is just the thrill of the players, and the exuberance in each supporter's mind. There is no further entity called the 'glory'. Green was a liberal.
25. Social Practice / C. Rights / 4. Property rights
The ground of property ownership is not force but the power to use it for social ends [Green,TH, by Muirhead]
     Full Idea: It is not the power of forcible tenure but the power of utilisation for social ends that is the ground of the permanent recognition that constitutes a right to property.
     From: report of T.H. Green (Lectures on the Principles of Political Obligation [1882]) by John H. Muirhead - The Service of the State III
     A reaction: Tell that to the aristocratic owners of British grouse moors! This just seems to be wishful thinking. Does that mean that I have no right to property if my ends are not 'social'?
Property is needed by all citizens, to empower them to achieve social goods [Green,TH]
     Full Idea: The rationale of property is that every one should be secured by society in the power of getting and keeping the means of realising a will which in possibility is a will directed to social good.
     From: T.H. Green (Lectures on the Principles of Political Obligation [1882], §220), quoted by John H. Muirhead - The Service of the State III
     A reaction: An interesting argument. If you want free citizens in a liberal society to be capable of achieving social good, you must allow them the right to acquire the means of doing so.
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / a. Final purpose
If something develops, its true nature is embodied in its end [Green,TH]
     Full Idea: To anyone who understands a process of development, the result being developed is the reality; and it is its ability to become this that the subject undergoing development has its true nature.
     From: T.H. Green (works [1875], iii: 224), quoted by John H. Muirhead - The Service of the State II
     A reaction: Although this contains the dubious Hegelian idea that development tends towards some 'end', presented as fixed and final, it still seems important that anything accepted as a 'development' is the expression of some natural potential.
28. God / A. Divine Nature / 1. God
God is the ideal end of the mature mind's final development [Green,TH]
     Full Idea: God is a subject which is eternally all that the self-conscious subject as developed in time has the possibility of becoming.
     From: T.H. Green (works [1875]), quoted by John H. Muirhead - The Service of the State I
     A reaction: [Ethics p.197] Reminiscent of Peirce's account of truth, as the ideal end of enquiry. If God is a human ideal, we either limit God, or exaggerate our powers of idealisation.
28. God / C. Attitudes to God / 4. God Reflects Humanity
God is the realisation of the possibilities of each man's self [Green,TH]
     Full Idea: God is identical with the self of every man in the sense of being the realisation of its determinate possibilities.…In being conscious of himself man is conscious of God and thus knows that God is, but only in so far as he knows what he himself really is.
     From: T.H. Green (works [1875], iii:226-7), quoted by John H. Muirhead - The Service of the State II
     A reaction: Does this, by the transitivity of identity, imply the identity of all individual men? Do we all contain identical possibilities, which converge on a unified concept of God? I always take the monotheistic God to far exceed mere human possibilities.
