| 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. |
| 21844 | The history of philosophy is an agent of power: how can you think if you haven't read the great names? [Deleuze] |
| Full Idea: The history of philosophy has always been the agent of power in philosophy, and even in thought. It has played the oppressor's role: how can you think without having read Plato, Descartes, Kant and Heidegger. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], I) | |
| A reaction: I find it hard to relate to this French 1960s obsession with everybody being oppressed in every conceivable way, so that 'liberation' is the only value that matters. If you ask why liberty is needed, you seem to have missed the point. |
| 21849 | Thought should be thrown like a stone from a war-machine [Deleuze] |
| Full Idea: Thought should be thrown like a stone by a war-machine. …Isn't this what Nietzsche does with an aphorism? | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], II) | |
| A reaction: It sounds as if philosophy should consist of nothing but aphorisms. |
| 21845 | Philosophy aims to become the official language, supporting orthodoxy and the state [Deleuze] |
| Full Idea: Philosophy is shot through with the project of becoming the official language of a Pure State. The exercise of thought thus conforms to the goals of the real State, to the dominant meanings and to the requirements of the established order. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], I) | |
| A reaction: [He cites Nietzsche's 'Schopenhauer as Educator' as the source of this] Is Karl Marx included in this generalisation, or Diogenes of Sinope? Is conservative philosophy thereby invalidated? |
| 21839 | When I meet objections I just move on; they never contribute anything [Deleuze] |
| Full Idea: Not reflection, and objections are even worse. Every time someone puts an objection to me, I want to say: 'OK, OK, let's get on to something else'. Objections have never contributed anything. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], I) | |
| A reaction: I know it is heresy in analytic philosophy, but I love this! In analytic seminars you can barely complete your first sentence before someone interrupts. It's like road range - the philosophical mind state is always poised to attack, attack. |
| 21841 | We must create new words, and treat them as normal, and as if designating real things. [Deleuze] |
| Full Idea: Let us create extraordinary words, on condition that they be put to the most ordinary use and that the entity they designate be made to exist in the same way as the most common object. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], I) | |
| A reaction: This sounds like the attitude of someone creating a computer game. A language game! The idea is to create concepts with which to 'palpitate' our conceptual scheme, in order to reveal it, and thus put it within our power. |
| 21842 | Don't assess ideas for truth or justice; look for another idea, and establish a relationship with it [Deleuze] |
| Full Idea: You should not try to find whether an idea is just or correct. You should look for a completely different idea, elsewhere, in another area, so that something passes between the two which is neither in one nor the other. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], I) | |
| A reaction: Neither relativism nor dialectic. Sounds like just having fun with ideas, but a commentator tells me it is a strategy for liberating our thought, following an agenda created by Nietzsche. |
| 21850 | Dualisms can be undone from within, by tracing connections, and drawing them to a new path [Deleuze] |
| Full Idea: It is always possible to undo dualisms from the inside, by tracing the line of flight which passes between the two terms or the two sets …and which draws both into a non-parallel evolution. At least this does not belong to the dialectic. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], II) | |
| A reaction: Deleuze disliked Hegel's version of the dialectic. Not clear what he means here, but he is evidently groping for an alternative account of the reasoning process, which is interesting. Deleuze hates rigid dualisms. |
| 21838 | Before we seek solutions, it is important to invent problems [Deleuze] |
| Full Idea: The art of constructing a problem is very important: you invent a problem, a problem-position, before finding a solution. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], I) | |
| A reaction: I get the impression that Deleuze prefers problems to solutions, so the activity of exploring the problem is all that really matters. Sceptics accuse philosophers of inventing pseudo-problems. We must first know why 'problematising' is good. |
| 20752 | For man, being is not what he is, but what he is going to be [Ortega y Gassett] |
| Full Idea: Being consists not in what it is already, but in what it is not yet, a being that consists in not-yet-being. Everything else in the world is what it is….Man is the entity that makes himself….He has to determine what he is going to be. | |
| From: José Ortega y Gassett (Toward a Philosophy of History [1941], p.112,201-2), quoted by Kevin Aho - Existentialism: an introduction 4 'Problem' | |
| A reaction: [p.112 and 201-2] This seems to be Ortega y Gasset's spin on Heidegger's concept, by adding a temporal dimension to it. |
| 21847 | Before Being there is politics [Deleuze] |
| Full Idea: Before Being there is politics. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], I) | |
| A reaction: [He says he is quoting Felix Guattari] I can only think that this is a very Marxist view - that politics permeates and dictates everything. This seems to tell me that I am forever controlled by something so deep and vast that I can never understand it. |
| 21840 | A meeting of man and animal can be deterritorialization (like a wasp with an orchid) [Deleuze] |
| Full Idea: The wasp becomes part of the orchid's reproductive apparatus at the same time as the orchid becomes the sexual organ of the wasp. …There are becomings where a man and an animal only meet on the trajectory of a common but asymmetrical deterritorialization. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], I) | |
| A reaction: [second bit compressed] The point here is to illustrate 'deterritorialization', a term which Deleuze got from Guattari. It seems to be where the margins of your being become unclear. Recall the externalist, anti-individualist view of mind. |
| 21843 | People consist of many undetermined lines, some rigid, some supple, some 'lines of flight' [Deleuze] |
| Full Idea: Things, people, are made up of varied lines, and they do not necessarily know which line they are on or where they should make the line which they are tracing pass; there is a whole geography in people, with rigid lines, supple lines, lines of flight etc. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], I) | |
| A reaction: An example of Deleuze creating a novel concept, in order to generate a liberating way of seeing our lives. His big focus is on 'lines of flight' (which, I think, are less restrained by local culture than the others). |
| 20756 | Instead of having a nature, man only has a history [Ortega y Gassett] |
| Full Idea: Man lives in view of the past. Man, in a word, has no nature; what he has is history. Expressed differently: what nature is to things, history is to man. | |
| From: José Ortega y Gassett (Toward a Philosophy of History [1941], p.217), quoted by Kevin Aho - Existentialism: an introduction 5 'Situated' | |
| A reaction: Makes explicit the existentialist denial of human nature. The foundation of ethics can only be total freedom, to choose both yourself and your actions. What is inescapable is the social and culture contexts. What is the role of the 'history'? |
| 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'. |
| 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] |
| 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. |
| 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'. |
| 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. |
| 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. |
| 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. |
| 21848 | Some lines (of flight) are becomings which escape the system [Deleuze] |
| Full Idea: There are lines which do not amount to the path of a point, which break free from structure - lines of flight, becomings, without future or past, without memory, which resist the binary machine. …The rhizome is all this. | |
| From: Gilles Deleuze (A Conversation: what is it? What is it for? [1977], II) | |
| A reaction: The binary machine enforces simplistic either/or choices. I assume the 'lines' are to replace the Self, with something much more indeterminate, active and changing. |
| 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. |
| 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. |
| 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. |
