2. Reason / A. Nature of Reason / 9. Limits of Reason
Reason leads to prudent selfishness, which overrules natural compassion [Rousseau]
     Full Idea: Reason is what engenders egocentrism ...turns man in upon himself ...and separates him from all that troubles him and afflicts him. Philosophy is what ...moves him to say at the sight of a suffering man 'Perish if you will; I am safe and sound'.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: He goes on to observe that fights in the marketplace are stopped by women, while the philosophers have all run away! This thinking leads to the sentimental movement, and then to romanticism.
11. Knowledge Aims / A. Knowledge / 1. Knowledge
No one would bother to reason, and try to know things, without a desire for enjoyment [Rousseau]
     Full Idea: We seek to know only because we desire to find enjoyment; and it is impossible to conceive why someon who had neither desires nor fears would go to the bother reasoning.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: This appears to be an echo of Hume's pessimism about the autonomy of reason. This downgrading of reason is a striking feature of the Enlightenment, which presumably culminates in the romantic movement.
15. Nature of Minds / C. Capacities of Minds / 5. Generalisation by mind
General ideas are purely intellectual; imagining them is immediately particular [Rousseau]
     Full Idea: Every general idea is purely intellectual. The least involvement of the imagination thereupon makes the idea particular.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: This thought is in Berkeley, who seemed to think that general ideas were impossible, because imagination was always required. Rousseau is certainly an improvement on that.
Only words can introduce general ideas into the mind [Rousseau]
     Full Idea: General ideas can be introduced into the mind only with the aid of words.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: Hm. How did humanity manage to invent general words. Do animals not have general thoughts, e.g. about food, shelter, predators? Roussea goes on to deny that monkeys see nuts as a 'type' of fruit.
18. Thought / D. Concepts / 5. Concepts and Language / a. Concepts and language
Language may aid thinking, but powerful thought was needed to produce language [Rousseau]
     Full Idea: If men needed speech in order to learn to think, they had a still greater need for knowing how to think in order to discover the art of speaking.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: I take language to be a consequence of the emergence of meta-thought in humanity, so I thoroughly endorse Rousseau's view. The idea that rationality, and even consciousness, are mainly facilitated by language strikes me as quite wrong.
19. Language / D. Propositions / 3. Concrete Propositions
Propositions (such as 'that dog is barking') only exist if their items exist [Williamson]
     Full Idea: A proposition about an item exists only if that item exists... how could something be the proposition that that dog is barking in circumstances in which that dog does not exist?
     From: Timothy Williamson (Necessary Existents [2002], p.240), quoted by Trenton Merricks - Propositions
     A reaction: This is a view of propositions I can't make sense of. If I'm under an illusion that there is a dog barking nearby, when there isn't one, can I not say 'that dog is barking'? If I haven't expressed a proposition, what have I done?
20. Action / C. Motives for Action / 4. Responsibility for Actions
Legal excuses are duress, ignorance, and diminished responsibility [McMahan]
     Full Idea: The common legal practice is to distinguish three broad categories of excuse: duress, epistemic limitation, and diminished responsibility.
     From: Jeff McMahan (Killing in War [2009], 3.2.1)
     A reaction: McMahan cites these with reference to soldiers in wartime, but they have general application. The third one seems particularly open to very wide interpretation. Presumably I can't be excused by just being irresponsible.
21. Aesthetics / A. Aesthetic Experience / 4. Beauty
Without love, what use is beauty? [Rousseau]
     Full Idea: Where there is no love, what use is beauty?
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: Rousseau seems to be thinking of sexual attractiveness, but the aphorism seems to have universal application.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / b. Rational ethics
Rational morality is OK for brainy people, but ordinary life can't rely on that [Rousseau]
     Full Idea: Although it might be appropriate for Socrates and minds of his stature to acquire virtue through reason, the human race would long ago have ceased to exist, if its preservation had depended solely on the reasonings of its members.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: He takes our natural compassion to be the basis of morality. Hume combines that with a natural social prudence. Apes live successfully together in groups, without a Socrates. See MacIntyre on the failure of reasoned morality.
22. Metaethics / C. The Good / 1. Goodness / h. Good as benefit
If we should not mistreat humans, it is mainly because of sentience, not rationality [Rousseau]
     Full Idea: If I am obliged not to do any harm to my fellow man, it is less because he is a rational being than because he is a sentient being.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref)
     A reaction: How should sentience and rationality be weighted here? Kant demands instrinsic respect for beings on the grounds of their rationality. What could ever justify doing needless harm to anything? An open goal for virtue theory here.
23. Ethics / B. Contract Ethics / 2. Golden Rule
The better Golden Rule is 'do good for yourself without harming others' [Rousseau]
     Full Idea: Instead of the sublime maxim of reasoned justice 'Do unto others as you would have them do unto you', pity inspires a less perfect but perhaps more useful one: 'Do what is good for you with as little harm as possible to others'.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: His revised maxim is like J.S. Mill's formula for liberalism. The first maxim seems more contractarian, the second more utilitarian.
23. Ethics / C. Virtue Theory / 3. Virtues / f. Compassion
The fact that we weep (e.g. in theatres) shows that we are naturally compassionate [Rousseau]
     Full Idea: Every day one sees in our theatres someone affected and weeping at the ills of some unfortunate person ...Nature, in giving men tears, bears witness that she gave the human race the softest hearts.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: Lovely. Of course, tears in infants are for their own misfortunes, but adults more commonly weep over the sufferings of others. But we somewhat laugh at people who easily cry over dramas about suffering.
24. Political Theory / A. Basis of a State / 1. A People / a. Human distinctiveness
Humans are less distinguished from other animals by understanding, than by being free agents [Rousseau]
     Full Idea: It is not so much understanding which causes the specific distinction of man from all other animals as it is his being a free agent.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: I'm not sure how deep Rousseau takes 'free' to go. Having little enthusiasm for free will, I would say that we are distinguished by the complexity of our decision making. But I attribute that to meta-thought, the mark of humanity.
24. Political Theory / A. Basis of a State / 1. A People / b. The natural life
Most human ills are self-inflicted; the simple, solitary, regular natural life is good [Rousseau]
     Full Idea: Most of our ills are of our own making, and we could have avoided nearly all of them by preserving the simple, regular and solitary lifestyle prescribed to us by nature.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: It is important that he is not really disagreeing with Hobbes's pessimistic view of natural life as 'nasty'. Rousseau attributes that to a later stage, when people are ineptly beginning to emerge from the state of nature. I'm an optimist here.
Is language a pre-requisite for society, or might it emerge afterwards? [Rousseau]
     Full Idea: Which was more necessary: an already formed society for the invention of languages, or an already invented language for the establishment of society?
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: Rousseau declines to attempt an answer. Ants and bees seem to do well, but have some means of communication. Ape colonies are quite sophisticated.
I doubt whether a savage person ever complains of life, or considers suicide [Rousseau]
     Full Idea: I ask if anyone has ever heard tell of a savage who was living in liberty ever dreaming of complaining about his life and of killing himself.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: Rousseau's state of nature is much too remote from any current tribal life for this to be tested. It is a nice speculation. Do apes ever attempt suicide?
Leisure led to envy, inequality, vice and revenge, which we now see in savages [Rousseau]
     Full Idea: People developed leisure pursuits, and wanted esteem, which was the first step towards inequality, and at the same time towards vice. Vanity, contempt, shame and envy were born, and acts of revenge. This is the stage of savage people we know of.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: [very compressed] This is important in understanding Rousseau, because his happier 'state of nature' is prior to what is described here, which is the violent warlike state which impressed Hobbes.
Primitive man was very gentle [Rousseau]
     Full Idea: Nothing is so gentle as man in his primitive state.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: This summarises Rousseau's view of the earliest stage of mankind, when there was little rivalry, and little motivation or opportunity for viciousness.
Our two starting principles are concern for self-interest, and compassion for others [Rousseau]
     Full Idea: One principle prior to reason makes us ardently interested in our well-being and self-preservation; the other inspires a natural repugnance to seeing any sentient being, especially our fellow man, perish or suffer.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref)
     A reaction: This is strikingly like Hume's nascent utilitarianism. These two principles are the key to Rousseau's vision of the state of nature, from which the union around a general will leads to the formation of a state. Note that animals get included here.
Savages avoid evil because they are calm, and never think of it (not because they know goodness) [Rousseau]
     Full Idea: We could say that savages are not evil because they do not know what is good; for it is neither enlightenment nor legal restraint, but the calm of the passions and the ignorance of vice which prevents them from doing evil.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: Suggests one of my favourite ideas (Idea 519). While his hopes for savages and the state of nature may be optimistic, the idea that you won't do evil if it never crosses your mind (and it won't if you are a calm person) is very powerful.
Savage men quietly pursue desires, without the havoc of modern frenzied imagination [Rousseau]
     Full Idea: Imagination, which wreaks so much havoc among us, does not speak to savage hearts; each man peacefully awaits the impetus of nature, gives himself over to it without choice, and with more pleasure than frenzy; then all desire is snuffed out.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: Interesting to identify imagination as a source of trouble. The idea that the savage lacks imagination seems implausible. Better to say that modern imagination has been poisoned by competition.
24. Political Theory / A. Basis of a State / 3. Natural Values / a. Natural freedom
A savage can steal fruit or a home, but there is no means of achieving obedience [Rousseau]
     Full Idea: A savage man could well lay hold of the fruit another has gathered, the cave that served as his shelter. But how will he ever succeed in making himself obeyed? What can be the chain of dependence among men who possess nothing?
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: You'd certainly need language to express an enduring threat, like excluding someone from all of the local caves. You need to be able to say 'I'll be back', which animals can't say. Huge muscular men must have dominated in some way.
24. Political Theory / A. Basis of a State / 3. Natural Values / b. Natural equality
In a state of nature people are much more equal; it is society which increases inequalities [Rousseau]
     Full Idea: There must be much less difference between one man and another in the state of nature than in that of society, and natural inequality must increase in the human species through inequality occasioned by social institutions.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: This is the main idea of his essay - the answer to the question set by the essay prize. Slavery is common in fairly basic societies, but that is at a much more advanced stage than Rousseau is thinking of. It's hard to disagree with him.
It is against nature for children to rule old men, fools to rule the wise, and the rich to hog resources [Rousseau]
     Full Idea: It is obviously contrary to the law of nature, however it is defined, for a child to command an old man, for an imbecile to lead a wise man, and for a handful of people to gorge themselves on superfluities while the starving multitude lack necessities.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: I wonder if gregarious animals ever starve to death during a time of plenty, because of social exclusion? I bet this idea was quoted widely in 1780s Paris. The massive inequality is not just nasty, but 'contrary to the law of nature'.
24. Political Theory / B. Nature of a State / 2. State Legitimacy / a. Sovereignty
People accept the right to be commanded, because they themselves wish to command [Rousseau]
     Full Idea: Citizens allow themselves to be oppressed only insofar as they are driven by blind ambition; ...they consent to wear chains in order to be able to give them in turn to others. It is difficult to reduce to obedience someone who does not wish to command.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: Beautiful. This produces what I call the 'military model of management', where people love tree diagrams showing chains of command, and their place in the hierarchy. Life becomes 'either give orders, or obey'. I like democratic teams.
24. Political Theory / B. Nature of a State / 5. Culture
We seem to have made individual progress since savagery, but actually the species has decayed [Rousseau]
     Full Idea: Evidence confirms that the savage state is the youth of the world, and all subsequent progress has been in appearance so many steps toward the perfection of the individual, and in fact toward the decay of the species.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: This strikes me as an attack on the new rising philosophy of liberalism, and a plea for communitarianism. We should judge humanity as a whole, and not just look at some individual lives which seem to be going well.
24. Political Theory / C. Ruling a State / 4. Changing the State / c. Revolution
Revolutionaries usually confuse liberty with total freedom, and end up with heavier chains [Rousseau]
     Full Idea: If people try to shake off a yoke, they put more distance between themselves and liberty, because in mistaking for liberty an unbridled licence which is its opposite, their revolutions usually deliver them over to seducers who make their chains heavier.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Intro letter)
     A reaction: This 'Animal Farm' thought was presumably ignored in 1789 and 1917. There must be basic rules for revolutionaries, of which priorities they must never drop from sight, and which priorities are dangerous and misleading.
24. Political Theory / D. Ideologies / 5. Democracy / b. Consultation
Plebiscites are bad, because they exclude the leaders from crucial decisions [Rousseau]
     Full Idea: I would not approve of plebiscites like those of the Romans where the state's leaders and those most interested in its preservation were excluded from the deliberations on which its safety often depended.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Intro letter)
     A reaction: I wish David Cameron had read this before 2016. This is exactly what happened with the Brexit referendum, where the people voted for an action entirely opposed to the preference of the majority of their elected representatives. Chaos ensued.
24. Political Theory / D. Ideologies / 5. Democracy / c. Direct democracy
In a direct democracy, only the leaders should be able to propose new laws [Rousseau]
     Full Idea: In order to stop ...the dangerous innovations that finally ruined Athens, no one would have the power to propose new laws according to his fancy; this right belongs exclusively to the magistrates.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Intro letter)
     A reaction: Aristotle says (somewhere!) that control of the agenda for meetings is the key issue in democracies. I assume any citizen can propose a law, but only a magistrate can put it on the agenda. Maybe a separate 'citizen's committee' could filter suggestions.
25. Social Practice / A. Freedoms / 1. Slavery
People must be made dependent before they can be enslaved [Rousseau]
     Full Idea: It is impossible to enslave a man without having first put him in the position of being incapable of doing without another.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: Ah yes. The key to running a slave plantation is not the threat of violence, but control of the shelter and food supply.
Enslaved peoples often boast of their condition, calling it a state of 'peace' [Rousseau]
     Full Idea: Enslaved peoples do nothing but boast of the peace and tranquillity they enjoy in their chains and they give the name 'peace' to the most miserable slavery.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: It seems to be a sad truth that enslaved peoples are less upset about their condition than outside observers are, especially in modern times, where slavery is usually deemed unacceptable. Slavery might be the best you can hope for.
If the child of a slave woman is born a slave, then a man is not born a man [Rousseau]
     Full Idea: The jurists who have gravely pronounced that the child of a slave woman is born a slave, have decided, in other words, that a man is not born a man.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: The hidden premise of this enthymeme is that man is born free. A key issue of liberalism is the status of children. Are the children of religious believers automatically members of that sect? Can I be born a West Ham supporter?
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
Like rich food, liberty can ruin people who are too weak to cope with it [Rousseau]
     Full Idea: Liberty is like those solid foods or full-bodied wines appropriate for strengthening robust constitutions that are used to them, but which overpower, ruin and intoxicate the weak and delicate who are not suited to them.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Intro letter)
     A reaction: Rousseau vision of a successful society involves robustly self-sufficient citizens (as in the American ideal), rather than people who are free, but easily led into dependence (in a 'nanny state').
25. Social Practice / B. Equalities / 1. Grounds of equality
Three stages of the state produce inequalities of wealth, power, and enslavement [Rousseau]
     Full Idea: Stage one gives law and property (producing inequalities of rich and poor), stage two gives a magistracy (producing weak and strong), and stage three is legitimate power becoming arbitrary (producing master and slave).
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: This is the final answer to the prize essay question (with Idea 19772). What a beautiful analysis - and he didn't even win the prize this time!
25. Social Practice / B. Equalities / 4. Economic equality
The pleasure of wealth and power is largely seeing others deprived of them [Rousseau]
     Full Idea: If one sees a handful of powerful and rich men at the height of greatness and fortune while the mob grovels in obscurity and misery, it is because the former prize the things they enjoy only to the extent that the others are deprived of them.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: This seems to be an accurate picture of ancien régime France, and it still applies to modern plutocrats. The pleasure of a nice house is not that it is very good, but that it is better than other houses. Inequality gives a lot of pleasure!
25. Social Practice / C. Rights / 1. Basis of Rights
Liberty Rights are permissions, and Claim Rights are freedom from intervention [McMahan]
     Full Idea: There are two types of right. A Liberty right is merely a permission, meaning it is not wrong to do it. But a Claim right is a right against intervention, meaning no one has a liberty right to prevent it.
     From: Jeff McMahan (Killing in War [2009], 2.3)
     A reaction: There must also be a third type of right, which requires other people to perform actions on your behalf. If you pay for a book in a shop, you must then be given the book.
25. Social Practice / C. Rights / 4. Property rights
Persuading other people that some land was 'owned' was the beginning of society [Rousseau]
     Full Idea: The first person who, having enclosed a plot of land, took it into his head to say 'this is mine' and found people simple enough to believe him, was the true founder of civil society.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: A wonderful riposte to Locke, who thought political legitimacy was based on property! Locke is way too simplistic about whether someone has a true right to their property. Highy dubious claims become ossified after a generation or two.
What else could property arise from, but the labour people add to it? [Rousseau]
     Full Idea: It is impossible to conceive of the idea of property arising from anything but manual labour, for it is not clear what man can add, beyond his own labour, in order to appropriate things he has not made.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: A thorough endorsement of Locke's labour theory of value. It is not clear to me why you have to 'add' something in order to achieve ownership. Don't you own firewood just by picking it up? Golfers give ownership of a lost ball to the first one to see it.
Land cultivation led to a general right of ownership, administered justly [Rousseau]
     Full Idea: From the cultivation of land, there necessarily followed the division of land; and from property once recognised, the first rules of justice. For in order to render everyone what is his, it is necessary that everyone can have something.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: This looks rather obviously correct. You don't plant crops if you are not protected in your right to reap what you have sown, and you would expect to re-sow from the proceeds. Other people will want you to do this.
If we have a natural right to property, what exactly does 'belonging to' mean? [Rousseau]
     Full Idea: Others have spoken of the natural right that everyone has to preserve what belongs to him, without explaining what they mean by 'belonging'.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref)
     A reaction: This is aimed at Locke. What Marxists will challenge is the legitimacy of property ownership, granted by patronage, enclosure, exploitation and conquest. These start as injustices, but that fades after a few generations. Locke has a labour-theory.
25. Social Practice / D. Justice / 2. The Law / c. Natural law
Writers just propose natural law as the likely useful agreements among people [Rousseau]
     Full Idea: Writers begin by seeking the rules on which, for the common utility, it would be appropriate for men to agree among themselves; they then give the name of 'natural law' to these rules, with no other proof than their presumed good results.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref)
     A reaction: The arguments for natural law strike me as quite good, but pinning down its content looks incredibly elusive, and at the mercy of cultural influences.
25. Social Practice / D. Justice / 3. Punishment / b. Retribution for crime
Primitive people simply redressed the evil caused by violence, without thought of punishing [Rousseau]
     Full Idea: More primitive men regarded the acts of violence that could befall them as an easily redressed evil and not as an offence that must be punished; they did not even dream of vengeance, except as a knee-jerk response.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: This may be Rousseau at his most optimistic, trying to deny a rather more aggressive streak in people, seen in children's playgrounds.
25. Social Practice / E. Policies / 1. War / a. Just wars
Wars can be unjust, despite a just cause, if they are unnecessary or excessive or of mixed cause [McMahan]
     Full Idea: Wars can be unjust despite having a just cause, because they are not actually needed, or they will cause excessive harm, or they also pursue some unjust causes.
     From: Jeff McMahan (Killing in War [2009], 1.1)
     A reaction: [compressed] The point is that older writers often think that a 'just cause' is sufficient. He is obviously right.
Just war theory says all and only persons posing a threat are liable to attack [McMahan]
     Full Idea: In mainstream just war theory (Anscombe, Nagel, Walzer) the criterion of liability to attack is simply posing a threat. Since all combatants pose a threat to each other, they are morally liable to attack; because noncombatants do not, they are not liable.
     From: Jeff McMahan (Killing in War [2009], 1.2)
     A reaction: McMahan says that the distinction between legitimate and illegitimate targets rests mostly on this basis. The problem is that a huge range of unarmed people can also pose various degrees of threat.
You (e.g. a police officer) are not liable to attack just because you pose a threat [McMahan]
     Full Idea: It is false that by posing a threat to another, one necessarily makes oneself liable to defensive action. A police officer who shoots an active murderer does not thereby by make herself liable to defensive action.
     From: Jeff McMahan (Killing in War [2009], 1.2)
     A reaction: This is one of his arguments against the moral equality of combatants. It is not morally OK to shoot all the local soldiers when you unjustly invade a territory. Sounds right to me.
The worst unjustified wars have no aim at all [McMahan]
     Full Idea: The most serious reason why a war might be unjustified is that it lacks any justifying aim at all.
     From: Jeff McMahan (Killing in War [2009], 1.1)
     A reaction: It seems that Louis XIV invaded the Netherlands in around 1674 purely to enhance his own glory. That strikes me as worse. I supposed Ghenghis Khan invaded places simply because he enjoyed fighting.
A defensive war is unjust, if it is responding to a just war [McMahan]
     Full Idea: It is possible for a defensive war to be unjust, when the defensive war to which it is a response is a just war.
     From: Jeff McMahan (Killing in War [2009], 3.3.3)
     A reaction: An example might be a state resisting an intervention from outside, when the state is in the process of exterminating some unwanted minority. Or perhaps the invaders are crossing the state's territory to achieve some admirable end.
A person or state may be attacked if they are responsible for an unjustified threat [McMahan]
     Full Idea: It is a necessary condition of liability to defensive attack that one be morally responsible for posing an objectively unjustified threat.
     From: Jeff McMahan (Killing in War [2009], 4.1.1)
     A reaction: This implies that one may not actually be doing the threatening (but merely ordering it, or enabling it). McMahan aims to have the same criteria for wartime as for peacetime. He denies Anscombe's claim that merely posing the threat is enough.
25. Social Practice / E. Policies / 1. War / b. Justice in war
Proportionality in fighting can't be judged independently of the justice of each side [McMahan]
     Full Idea: There is simply no satisfactory understanding of proportionality in war that can be applied independently of whether the acts that are evaluated support a just or an unjust cause.
     From: Jeff McMahan (Killing in War [2009], 1.3)
     A reaction: He rejects traditional just war theory, which sees both sides as morally equal in combat, and hence equally subject to the principles of proportional response. But the just can then be harsher, when their just principles should make them milder.
Can an army start an unjust war, and then fight justly to defend their own civilians? [McMahan]
     Full Idea: There is a paradox if the unjust are justified in fighting the just in order to protect their own civilians who have been endangered by the starting of an unjust war.
     From: Jeff McMahan (Killing in War [2009], 2.1)
     A reaction: [my summary of MacMahan pp.48-49] It suggests that in a war there may be local concepts of justice which are at odds with the general situation - which is the ad bellum/in bello distinction. But this is the justice of fighting, not how it is conducted.
Soldiers cannot freely fight in unjust wars, just because they behave well when fighting [McMahan]
     Full Idea: We must stop reassuring soldiers that they act permissibly when they fight in an unjust war, provided that they conduct themselve honorably on the battlefield by fighting in accordance with the rules of engagement.
     From: Jeff McMahan (Killing in War [2009], 2.8)
     A reaction: This culminates McMahan's arguments against the moral equality of combatants, and against the sharp division of justice of war from justice in war. How rare it is for philosophy to culminate in a policy recommendation!
The law of war differs from criminal law; attacking just combatants is immoral, but legal [McMahan]
     Full Idea: Unlike domestic criminal law, the law of war is designed not to protect moral rights but to prevent harm. …This means when unjust combatants attack just combatants they violate their moral rights, yet they act within their legal rights.
     From: Jeff McMahan (Killing in War [2009], 3.1.1)
     A reaction: He says we must bring the law of war much closer to the morality of war. If there is any hope of slowly eliminating war, it may lie in reforms such as these.
If the unjust combatants are morally excused they are innocent, so how can they be killed? [McMahan]
     Full Idea: If most unjust combatants are morally innocent because they are excused, and if it is wrong to intentionally kill morally innocent people, then a contingent form of pacificism may be inescapable.
     From: Jeff McMahan (Killing in War [2009], 3.3.1)
     A reaction: A very nice argument against the moral equality of combatants. If I think we are the good guys, and the opposing troops are no morally different from us, how can I possibly kill them?

You don't become a legitimate target, just because you violently resist an unjust attack [McMahan]
     Full Idea: It is hard to see how just combatants could become legitimate targets simply by offering violent resistance to unjust attacks by unjust coombatants.
     From: Jeff McMahan (Killing in War [2009], 1.3)
     A reaction: It is, however, hard to criticise a soldier who is dragged into fighting for an unjust cause, and then kills just defenders in the course of the fight. Once the bullets fly, normal morality seems to be suspended. Just survive.
If all combatants are seen as morally equal, that facilitates starting unjust wars [McMahan]
     Full Idea: It would be naïve to doubt that the widespread acceptance of the moral equality of combatants has facilitated the ability of governments to fight unjust wars.
     From: Jeff McMahan (Killing in War [2009], 1.1)
     A reaction: The point is that their armies are both compliant and seeing their actions as guiltless, which makes them perfect tools for evil. McMahan's ideal is an army which asks sharp questions about the justification of the war, before they fight it.
Volunteer soldiers accept the risk of attack, but they don't agree to it, or to their deaths [McMahan]
     Full Idea: When soldiers go to war, they undoubtedly assume a certain risk. They voluntarily expose themselves to a significant risk of being attacked. But this is entirely different from consenting to being attacked.
     From: Jeff McMahan (Killing in War [2009], 2.2.1)
     A reaction: This is his response to Walzer's thought that soldiers resemble people who volunteer for a boxing match. The sailors at Pearl Harbour obviously didn't consent to the attack, or accept the Japanese right to kill them.
If being part of a big collective relieves soldiers of moral responsibility, why not the leaders too? [McMahan]
     Full Idea: If acting as an agent of a political collective justifies the combatants fighting an unjust war, that should also release the leaders from responsibility for their role in the fighting of that war. No one ever explains why this is not so.
     From: Jeff McMahan (Killing in War [2009], 2.5)
     A reaction: At the very least there seems to be a problem of the cut off point between innocent soldiers and culpable leaders. Which rank in the army or executive triggers the blame?
If soldiers can't refuse to fight in unjust wars, can they choose to fight in just wars? [McMahan]
     Full Idea: There is a certain symmetry here. The permissibility of disobeying a command to fight in an unjust war suggests the permissibility of disobeying a command not to fight in a just war.
     From: Jeff McMahan (Killing in War [2009], 2.7)
     A reaction: The argument considered here is that since we could never allow soldiers to choose to fight in their own wars, we similarly cannot let them opt out of the official wars. Implying obedience is absolute. Soldiers don't get to 'choose' anything!
Equality is both sides have permission, or both sides are justified, or one justified the other permitted [McMahan]
     Full Idea: Moral equality means either 1) because just combatants are permitted to fight in a just way, so are the unjust , or 2) because the just are justified, so are the unjust, or 3) because the just are justified, the unjust are therefore permitted.
     From: Jeff McMahan (Killing in War [2009], 3.1.2)
     A reaction: [summary] McMahan calls 1) the weak version, and 2) the strong. He suggests that although 3) is unusual, it is what most people believe - that if the good are justified, the bad are permitted to fight back. He rejects them all.
Fighting unjustly under duress does not justify it, or permit it, but it may excuse it [McMahan]
     Full Idea: It is said that combatants are compelled to fight; they have no choice. But duress is not a justification; nor does it ground a permission - not even a subjective permission. It is, instead, an excusing condition.
     From: Jeff McMahan (Killing in War [2009], 3.1.2)
     A reaction: The 'subjective' permission is believing you are just, even if you aren't. A nice, accurate and true distinction made by McMahan, I think. It is roughly our postwar attitude to the Nazi army.
Soldiers cannot know enough facts to evaluate the justice of their war [McMahan]
     Full Idea: When soldiers are commanded to fight, they cannot reasonably be expected to have the factual knowledge necessary to evaluate the war as just or unjust.
     From: Jeff McMahan (Killing in War [2009], 2.3)
     A reaction: This is part of the 'epistemic' justification for a soldier to fight in an unjust war. Sometimes soldiers do have enoough knowledge, especially if they join up late on in a war, when they have studied and observed its progress.
25. Social Practice / E. Policies / 1. War / d. Non-combatants
Innocence implies not being morally responsible, rather than merely being guiltless [McMahan]
     Full Idea: My alternative conception is that one is 'innocent' if one is neither morally responsible for nor guilty of a wrong. Classical theory focused on guilt, but I think we should focus on moral responsibility (which is something less).
     From: Jeff McMahan (Killing in War [2009], 1.4)
     A reaction: This seems to make the supporters of evil equally liable to attack with its perpetrators. But you can observe perpetration a lot more easily than you can observe support.

A state of war remains after a conquest, if the losers don't accept the winners [Rousseau]
     Full Idea: The conqueror and conquered peoples always remain in a state of war with one another, unless the nation, returned to full liberty, were to choose voluntarily its conqueror as leader.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part II)
     A reaction: Tricky if part of the conquered nation accepts the conqueror, and the other part doesn't, as in France in 1940. In a permanent conquest the state of war seems to fade away, as in England in 1066.
Unconditional surrender can't be demanded, since evil losers still have legitimate conditions [McMahan]
     Full Idea: Achieving unconditional surrender can never be a justification for the continuation of war, since there are always conditions that a vanquished adversary, no matter how evil, can be justified in demanding.
     From: Jeff McMahan (Killing in War [2009], 3.3.1)
     A reaction: McMahan is particularly discussing Hiroshima, but this also applies to the European war in 1945. Presumably a civilised victor will grant the conditions which the losers would have demanded, and that probably happened in 1945. It's about power.
25. Social Practice / F. Life Issues / 6. Animal Rights
Both men and animals are sentient, which should give the latter the right not to be mistreated [Rousseau]
     Full Idea: Since being sentient is common to both animals and men, that should at least give the former the right not to be needlessly mistreated by the latter.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Pref)
     A reaction: This is why utilitarianism led to the founding of the RSPCA in Britain. There is a disturbing picture of people smashing up animals for fun, if they can only persuade themselves that the animals are not sentient. I've heard fishermen claim that.
26. Natural Theory / B. Natural Kinds / 2. Defining Kinds
Men started with too few particular names, but later had too few natural kind names [Rousseau]
     Full Idea: Men at first unduly multiplied the names of individual things, owing to their failure to know the genera and species, but later made too few genera and species, owing to their failure to have considered beings in all their differences.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: The fact that two leopards differ is not a good enough reason to assign them to two different general terms. Adjectives can do all the necessary modification. The single general term acknowledges something important.
27. Natural Reality / G. Biology / 3. Evolution
Small uninterrupted causes can have big effects [Rousseau]
     Full Idea: Negligible causes may have surprising power when they act without interruption.
     From: Jean-Jacques Rousseau (Discourse on the Origin of Inequality [1754], Part I)
     A reaction: A wonderfully simple observation that is a key idea of the theory of evolution. If life was created 6,000 years ago, evolution is impossible. If it appeared 500,000,000 years ago, how could evolution NOT occur? Little changes must occur.
