| 20678 | The Scientific Revolution was the discovery of our own ignorance [Harari] |
| Full Idea: The great discovery of the Scientific Revolution was that humans do not know the answers to their most important question. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 14 'Ignoramus') | |
| A reaction: I think of that revolution as raising the bar in epistemology, but this idea gives a motivation for doing so. Why the discovery then, and not before? |
| 20686 | For millenia people didn't know how to convert one type of energy into another [Harari] |
| Full Idea: For millenia people didn't know how to convert one type of energy into another, …and the only machine capable of performing energy conversion was the body. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 17 'Intro') | |
| A reaction: Hence the huge and revolutionary importance of the steam engine and the electricity generator. |
| 23027 | 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. |
| 23030 | 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. |
| 21982 | I only wish I had such eyes as to see Nobody! It's as much as I can do to see real people. [Carroll,L] |
| Full Idea: "I see nobody on the road," said Alice. - "I only wish I had such eyes," the King remarked. ..."To be able to see Nobody! ...Why, it's as much as I can do to see real people." | |
| From: Lewis Carroll (C.Dodgson) (Through the Looking Glass [1886], p.189), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.7 | |
| A reaction: [Moore quotes this, inevitably, in a chapter on Hegel] This may be a better candidate for the birth of philosophy of language than Frege's Groundwork. |
| 23044 | 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? |
| 23034 | 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. |
| 23032 | 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. |
| 23033 | 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. |
| 20692 | Money does produce happiness, but only up to a point [Harari] |
| Full Idea: An interesting conclusion (from questionnaires) is that money does indeed bring happiness. But only up to a point, and beyond that point it has little significance. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 19 'Counting') | |
| A reaction: The question is whether that flattening-off point is relative to those around us, or absolute, according to the needs of living. Though these two may not be separate. |
| 20663 | If a group is bound by gossip, the natural size is 150 people [Harari] |
| Full Idea: Sociological research has shown that the maximum 'natural' size of a group bound by gossip is about 150 individuals. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 02 'Legend') | |
| A reaction: On the other hand, most of us can learn the names of a group of about 450. Maybe the 'known' group and the 'gossip' group are equally significant. Not much use for a modern state, but of interest to communitarians. |
| 20677 | Since 1500 human population has increased fourteenfold, and consumption far more [Harari] |
| Full Idea: In the year 1500 there were about 500 million Homo sapiens in the world. Today there are 7 billion. …Human population has increased fourteenfold, our production 240-fold, and energy consumption 115-fold. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 14 'Discovery') | |
| A reaction: We really need to grasp how extraordinary this is. |
| 20688 | People 300m tons; domesticated animals 700m tons; larger wild animals 100m tons [Harari] |
| Full Idea: The combined mass of homo sapiens is about 300 million tons; the mass of all domesticated farmyard animals is about 700 million tons; the mass of the surviving larger wild animals (from porcupines up) is less than 100 million tons. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 18 'Permanent') | |
| A reaction: These really are figures that deserve much wider currency. Every school entrance hall needs a board with a few of the basic dramatic statistics about human life on Earth. |
| 20674 | The Nazi aim was to encourage progressive evolution, and avoid degeneration [Harari] |
| Full Idea: The main ambition of the Nazis was to protect humankind from degeneration and encourage its progressive evolution. …Given the state of scientific knowledge in 1933, Nazi beliefs were hardly outside the pale. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Worship') | |
| A reaction: It still sounds a fairly worthy ambition, close to the heart of educationalists everywhere. The problems start with the definition of 'degeneration' and 'progress'. |
| 23045 | 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. |
| 23050 | 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. |
| 23052 | 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. |
| 20679 | We stabilise societies with dogmas, either of dubious science, or of non-scientific values [Harari] |
| Full Idea: Modern attempts to stabilise the sociopolitical order either declare a scientific theory (such as racial theories for Nazis, or economic ones for Communists) to be an absolute truths, or declare non-scientific dogmas (such as liberal values) | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 14 'Ignoramus') | |
| A reaction: [compressed] |
| 23036 | 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. |
| 23039 | 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. |
| 20690 | The state fostered individualism, to break the power of family and community [Harari] |
| Full Idea: States and markets use their growing power to weaken the bonds of family and community. They made an offer that couldn't be refused - 'become individuals' (over marriage, jobs and residence). The 'romantic individual' is not a rebel against the state. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 18 'Collapse') | |
| A reaction: [compressed] See the film 'Breaking the Waves'. An interesting slant on the Romantic movement. See Wordsworth's 'Michael'. Capitalism needs shoppers with their own money, and a mobile workforce. |
| 23038 | 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. |
| 20689 | In 1750 losing your family and community meant death [Harari] |
| Full Idea: A person who lost her family and community around 1750 was as good as dead. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 18 'Collapse') | |
| A reaction: This is a very good advert for liberal individualism, and marks the downside of 'too much community'. |
| 20681 | The sacred command of capitalism is that profits must be used to increase production [Harari] |
| Full Idea: In the new capitalist creed, the first and most sacred commandment is: The profits of production must be reinvested in increasing production. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Growing') | |
| A reaction: In this sense, capitalism is less greedy than its predecessors. 17th century aristocratic monopolists simply spent the profits of their activities. See the gorgeous clothes then (and pyramids and palaces), and the quiet suits of capitalists. |
| 20682 | The main rule of capitalism is that all other goods depend on economic growth [Harari] |
| Full Idea: The principle tenet of capitalism is that economic growth is the supreme good, or at least a proxy for it, because justice, freedom, and even happiness all depend on economic growth. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Growing') | |
| A reaction: In this respect, the main opponent of captitalism is green politics, rather than marxism. |
| 20683 | The progress of capitalism depends entirely on the new discoveries and gadgets of science [Harari] |
| Full Idea: The history of capitalism is unintelligible without taking science into account. …The human economy has managed to keep on going only thanks to the fact that scientists come up with a new discovery or gadget every few years. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Growing') | |
| A reaction: For example, the desperate but unconvincing attempts to persuade us of the novelty of new models of car. Built-in obsolescence is needed once a design becomes static. |
| 20687 | In capitalism the rich invest, and the rest of us go shopping [Harari] |
| Full Idea: The supreme commandment of the rich is 'invest!', and the supreme commandment of the rest of us is 'buy!' | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 17 'Age') | |
| A reaction: Hence not only do the rich get much richer, while most of us remain roughly where we were, but there is a huge gulf between the investors and the non-investors. Encouraging small investors is a step forward. |
| 20685 | No market is free of political bias, and markets need protection of their freedoms [Harari] |
| Full Idea: There is no such thing as a market free of all political bias, …and markets by themselves offer no protection against fraud, theft and violence. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Cult') | |
| A reaction: Is this in theory, or in practice? In Sicily the free market has been a tool of the mafia. |
| 20693 | Freedom may work against us, as individuals can choose to leave, and make fewer commitments [Harari] |
| Full Idea: The freedom we value so highly may work against us. We can choose our spouses, friends and neighbours, but they can choose to leave us. With the individual wielding unprecedented power to decide her own path, we find it ever harder to make commitments. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 19 'Counting') | |
| A reaction: This is the worry of the communitarian. I take freedom to be a great social virtue - but an overrated one. |
| 20691 | Real peace is the implausibility of war (and not just its absence) [Harari] |
| Full Idea: Real peace is not the mere absence of war. Real peace is the implausibility of war. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 18 'Pax') | |
| A reaction: I have a nasty feeling that war only becomes implausible because it hasn't happened for a long time. War looked implausible for Britain in 1890. War certainly now looks implausible in western Europe. |
| 20684 | Financing is increasingly through credit rather than taxes; people prefer investing to taxation [Harari] |
| Full Idea: The European conquest of the world was increasingly financed through credit rather than taxes. …Nobody wants to pay taxes, but everyone is happy to invest. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 16 'Columbus') | |
| A reaction: This is presumably the mechanism that drives the unstoppable increase of the gulf between the rich and the poor in modern times. With investment, the rich get richer. |
| 20675 | The more you know about history, the harder it becomes to explain [Harari] |
| Full Idea: A distinguishing mark of history is that the better you know a historical period, the harder it becomes to explain why things happened one way and not another. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 13 'Hindsight') | |
| A reaction: Presumaby that means it resembles statistics. Each individual reading is perplexing, but some patterns emerge on the large scale. |
| 20676 | History teaches us that the present was not inevitable, and shows us the possibilities [Harari] |
| Full Idea: We study history not to know the future but to widen our horizons, to understand that our present situation is neither natural nor inevitable, and the we consequently have many more possibilities before us than we can imagine. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 13 'Hindsight') | |
| A reaction: On the whole winners forget history, and losers are branded through and through with it. If you don't know history, you can never understand the latter group. |
| 23040 | 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. |
| 23031 | 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. |
| 20671 | In order to explain both order and evil, a single evil creator is best, but no one favours that [Harari] |
| Full Idea: Monotheism explains order but not evil, and dualist religion explains evil but not order. One logical solution is a single omnipotent God who created the universe, and is evil - but nobody in history has had much stomach for that belief. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Battle') | |
| A reaction: Eh? Is there not also good, which also needs explaining? And there is some chaos to be explained too. Hume offers the best explanations. An inexperienced god, a team of squabbling gods, a god with shifting moods…. Study the facts first. |
| 23041 | 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. |
| 20664 | Animism is belief that every part of nature is aware and feeling, and can communicate [Harari] |
| Full Idea: Animism is the belief that almost every place, every animal, every plant and every natural phenomenon has awareness and feelings, and can communicated direct with humans. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 03 'Talking') | |
| A reaction: So does this count as a 'supernatural' belief system? It seems not, if the awareness is integral to the natural feature, and dies with it. Panpsychism is not supernatural either. A problem for anyone trying to define Naturalism. |
| 20666 | Most polytheist recognise one supreme power or law, behind the various gods [Harari] |
| Full Idea: Polytheism does not necessarily dispute the existence of a single power or law governing the entire universe. Most poytheist and even animist religions recognised such a supreme power that stands behind all the different gods, demons and holy rocks. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Benefits') | |
| A reaction: Presumably this one supreme power was always taken to be too remote for communication or worship. Are the other gods seen as slaves, or friends, or ambassadors of the Supreme One? |
| 20667 | Polytheism is open-minded, and rarely persecutes opponents [Harari] |
| Full Idea: Polytheism is inherently open-minded, and rarely persecutes 'heretics' and 'infidels'. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Benefits') | |
| A reaction: The Old Testament tells of the Jews turning on local pagans, and India was presumably tolerant Hindus encountering less tolerant Muslims. Then there's Christians in Africa. Dreadful bunch, the monotheists. Romans killed very few Christians. |
| 20665 | Mythologies are usual contracts with the gods, exchanging devotion for control of nature [Harari] |
| Full Idea: Much of ancient mythology is a legal contract in which humans promise everlasting devotion to the gods in exchange for mastery over plants and animals. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Silencing') | |
| A reaction: [He cites the first book of Genesis] So how readily do you swith allegiance, if someone else's gods are more successful? Why be loyal a loser. It should be like shopping - but I bet it wasn't. |
| 20669 | Dualist religions see everything as a battleground of good and evil forces [Harari] |
| Full Idea: Polytheism gave birth to monotheism, and to dualistic religions. Dualism explains that the entire universe is a battleground between good and evil forces, and everything that happens is part of that struggle. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Battle') | |
| A reaction: Presumably we are supposed to support the good guys, so the gods are not equals. God v Satan seems the right model, but Satan has to be beyond God's control, or else the problem of evil has to be solved. Empedocles held something like this. |
| 20670 | Dualist religions say the cosmos is a battleground, so can’t explain its order [Harari] |
| Full Idea: Dualist religions solve the problem of evil, but are unnerved by the Problem of Order. …If Good and Evil battle for control of the world, who enforces the laws governing this cosmic war? | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Battle') | |
| A reaction: You might explain it if one side was persistently winning, which is roughly God v Satan. |
| 20673 | Manichaeans and Gnostics: good made spirit, evil made flesh [Harari] |
| Full Idea: Manichaeans and Gnostics argued that the good god created the spirit and the soul, whereas matter and bodes are the creation of the evil god. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'Battle') | |
| A reaction: Hm. What motivated the evil god to do that? The evil god's achievement looks a lot more impressive. |
| 20668 | Monotheism appeared in Egypt in 1350 BCE, when the god Aten was declared supreme [Harari] |
| Full Idea: The first monotheist religion known to us appeared in Egypt c.1350 BCE, when Pharaoh Akenaten declared that one of minor deities of the Egyptian pantheon, the god Aten, was in fact the supreme power ruling the universe. | |
| From: Yuval Noah Harari (Sapiens: brief history of humankind [2014], 12 'God') | |
| A reaction: Zeus seems to have started like a tribal chief, and eventually turned into something like God. |
