30 ideas
There is no greater good for a warrior than to fight in a just war [Anon (Bhag)]
     Full Idea: There is no greater good for a warrior than to fight in righteous war.
     From: Anon (Bhag) (The Bhagavad Gita [c.500 BCE], 2.31)
     A reaction: What worries me now is not the urging to fight, as long as a good cause can be found, but the idea that someone should see his social role as 'warrior'. The modern 'soldier' is ready to fight, but a traditional 'warrior' is obliged to fight.
For Aquinas a war must be in a just cause, have proper authority, and aim at good [Aquinas, by Grayling]
     Full Idea: Aquinas argued that on three conditions war can be justified: first, that there is a just cause; second, that it is begun on proper authority; and third, that it is waged with right intention, for 'the advancement of good, or the avoidance of evil'.
     From: report of Thomas Aquinas (Summa Theologicae [1265], II) by A.C. Grayling - Among the Dead Cities Ch.6
     A reaction: But see also Idea 7292. Nowadays we are rightly suspicious of all three conditions. Evil people seem to think their cause is just; authority has often been seized by violence, or is being abused; and people seem confused about what is good or evil.
A desire to conquer, and men who do it, are always praised, or not blamed [Machiavelli]
     Full Idea: It is very natural and normal to wish to conquer, and when men do it who can, they always will be praised, or not blamed.
     From: Niccolo Machiavelli (The Prince [1513], Ch.3)
     A reaction: This view seems shocking to us, but it seems to me that this was a widely held view up until the time of Nietzsche, but came to a swift end with the invention of the machine gun in about 1885, followed by the heavy bomber and atomic bomb.
Only Utopians fail to see glory in warfare [More,T]
     Full Idea: Utopians are practically the only people on earth who fail to see anything glorious in war.
     From: Thomas More (Utopia [1516], Bk 2)
     A reaction: A refreshing thought for such an early date. Whatever dubious behaviour is nowadays attributed to Thomas More, you have to admire someone who writes this during the reign of Henry VIII.
The only just cause for a war is a wrong received [Vitoria]
     Full Idea: There is a single and only just cause for commencing a war, namely, a wrong received.
     From: Francis de Vitoria (On the Law of War [1525], p.170), quoted by Michael Walzer - Just and Unjust Wars 04
     A reaction: Walzer affirms this as one the principles of international law. In particular, mere differences of religion or politics cannot justify a war. The tricky bit is when the participants don't agree on the severity of the wrong.
Leaders can only attack foreigners who have done wrong (as with their own subjects) [Vitoria]
     Full Idea: A political leader cannot have greater authority over foreigners than over his own subjects; but he may not draw the sword against his own subjects unless they have done wrong; therefore he can only do so against foreigners in the same circumstances.
     From: Francis de Vitoria (On the Law of War [1525], p.303), quoted by Jeff McMahan - Killing in War 1.4
     A reaction: The question would then be whether they have 'done some wrong' against this leader, or against some other people (such as their fellow citizens). That would be the 'intervention' justification. Are they engaged in the wrong, or responsible for it?
The people (who have to fight) and not the head of state should declare a war [Kant]
     Full Idea: Each state must be organised so that the head of state, for whom the war costs nothing (for he wages it at the expense of the people) must no longer have the deciding vote on whether war is to be declared or not, for the people who pay for it must decide.
     From: Immanuel Kant (True in Theory, but not in Practice [1792], 3)
     A reaction: I would guess that he has Louis XIV particularly in mind. Imagine if Kant's proposal had been implemented in 1914. A referendum takes ages, and the people would need the facts (from the intelligence agencies).
Wars add strength to a nation, and cure internal dissension [Hegel]
     Full Idea: Not only do peoples emerge from wars with added strength, but nations troubled by civil dissension gain internal peace as a result of wars with their external enemies.
     From: Georg W.F.Hegel (Elements of the Philosophy of Right [1821], 324 add)
     A reaction: I suspect that Hegel quite likes wars because they accelerate the development of history. I don't think he would have written nonsense like this after WW1 and WW2. Leaders facing internal dissent like small external wars.
Modern wars arise from the study of history [Nietzsche]
     Full Idea: The great wars of our day are the effects of the study of history.
     From: Friedrich Nietzsche (Dawn (Daybreak) [1881], 180)
     A reaction: The Prussians reacted to Napoleon. The Nazis reacted to Versailles. But now the study of history reveals to us dreadful wars based on simplistic accounts of history. Be wise about history, not ignorant of it.
People will enthusiastically pursue an unwanted war, once sacrifices have been made [Nietzsche]
     Full Idea: All things for which we have made sacrifices are in the right. This explains why, just as soon as sacrifices are made, people continue with enthusiasm a war that was begun against their wishes.
     From: Friedrich Nietzsche (Human, All Too Human [1878], 229)
To renounce war is to renounce the grand life [Nietzsche]
     Full Idea: One has renounced grand life when one renounces war.
     From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.3)
     A reaction: Nietzsche was a medical orderly in the 1870 Franco-Prussian war, so he had seen it at first hand. I think the machine gun and the heavy bomber would have changed his attitude to warfare. He sounds a bit silly now. Nostalgia for the Iliad.
Modern wars are fought in the name of empty words which are given capital letters [Weil]
     Full Idea: For our contemporaries the role of Helen in the Trojan War is is played by words with capital letters. …When empty words are given capital letters, then, on the slightest pretext, men will begin shedding blood for them and piling up ruin in their name.
     From: Simone Weil (The Power of Words [1934], p.241)
     A reaction: This seems particularly true of the 1930s, where specific dogmatic ideologies seemed to grip and divide people. Simple aggressive nationalism seems to be the cause of current wars, now the fear of Communism has diminished.
The State requires self-preservation, but the war-machine desires destruction [Deleuze]
     Full Idea: There will always be a tension between the State apparatus with its requirement for self-preservation, and the war-machine in its undertaking to destroy the State, to destroy the subjects of the State, and even to destroy itself.
     From: Gilles Deleuze (Many Politics [1977], p.106)
     A reaction: This seems to fit WWI quite well, but the desire of the war-machine to destroy the State which pays for it sounds unlikely. Nevertheless war is appalling for the state, but it is the whole point of the war-machine, which gets restless.
Even non-violent intrusive acts between states count as aggression, if they justify resistance [Walzer]
     Full Idea: Every violation of an independent state is called aggression, which fails to differentiate between a seizure or imposition, and an actual conquest. …But what they have in common is that all aggressive acts justify forceful resistance.
     From: Michael Walzer (Just and Unjust Wars [1977], 04)
     A reaction: [compressed] Walzer concedes that this makes 'aggression' rather imprecise, and small acts can be used as an excuse for desired violent resistance. Each entrant in August 1914 seems to have had a slightly different motive.
The only good reason for fighting is in defence of rights [Walzer]
     Full Idea: The defence of rights is a reason for fighting. I want now to stress again, and finally, that it is the only reason.
     From: Michael Walzer (Just and Unjust Wars [1977], 04)
     A reaction: Walzer states at the beginning, without discussion, that his moral assumptions are based on the notion of rights. This is tricky because rights are assigned by some people to other people, and claims of rights can be challenged.
States can rightly pre-empt real and serious threats [Walzer]
     Full Idea: States can use force in the face of threats of war, if there is a serious risk to territory or independence. They are then forced to fight, and are the victims of aggression.
     From: Michael Walzer (Just and Unjust Wars [1977], 05)
     A reaction: [compressed] He uses this to justify Israeli pre-emptive strikes against Palestinians. I don't think his confident assertion of this principle is justified. It is open to massive abuse. There are, though, clearly situations where he is right.
Just wars are self-defence, or a rightful intercession in another's troubles [Walzer]
     Full Idea: Just wars may not be self-defence, if they are to help an independence struggle, or it is to save another country being invaded, or to prevent enslavement or massacre.
     From: Michael Walzer (Just and Unjust Wars [1977], 06)
     A reaction: [summary] Modern wars support some examples of these, but also suggest that without a long-term plan, or an understanding of the country they are entering, such intercessions may worsen the situation.
The aim of reprisals is to enforce the rules of war [Walzer]
     Full Idea: The purpose of reprisals is not to win the war or prevent defeat, but simply to enforce the rules [of war].
     From: Michael Walzer (Just and Unjust Wars [1977], 13)
     A reaction: That may be wishful thinking, since reprisals are often vastly more ruthless than the original offence, and there is often injustice in the nature of the reprisals, since they cannot be precise.
Reprisal is defensible, as an alternative to war [Walzer]
     Full Idea: Reprisal is the first resort of force. It is an alternative to war, and that description is an important argument in its favour.
     From: Michael Walzer (Just and Unjust Wars [1977], 13)
     A reaction: Enduring wrongs with dignity might be another alternative. Successful reprisals may be acceptable, but how do you assess their prospects?
States need not endure attacks passively, and successful reprisals are legitimate [Walzer]
     Full Idea: Whenever there is some substantial chance of success, reprisals are the legitimate resort of a victim state; for no state can be required passively to endure attacks upon its citizens.
     From: Michael Walzer (Just and Unjust Wars [1977], 13)
     A reaction: My concern is whether the reprisals have any direct connection to the attacks. They killed some of ours, so we will kill some of theirs is immoral. E.g. bombing Tripoli as reprisal for crashing the Lockerbie plane.
With nuclear weapons we have a permanent supreme emergency (which is unstable) [Walzer]
     Full Idea: With nuclear weapons, supreme emergency has become a permanent condition. …[283] But supreme emergency is never a stable position.
     From: Michael Walzer (Just and Unjust Wars [1977], 17)
     A reaction: The obvious instability of balanced mutual threat is a nuclear state which finds itself losing a war.
Nuclear bombs are not for normal war; they undermine the 'just war', with a new morality [Walzer]
     Full Idea: Nuclear weapons are not designed for war at all. …They explode the idea of a just war. They are the first technological innovations that are simply not encompassable within the familiar moral world.
     From: Michael Walzer (Just and Unjust Wars [1977], 17)
     A reaction: A nuclear war can hardly lead to normal victory, if it destroys the thing you are trying to conquer. It is like bringing a machine gun to a boxing match.
War must also have a good chance of success, and be waged with moderation [Grayling]
     Full Idea: To Aquinas's three conditions for war (Idea 7291) modern theorists have added two others: that to be just a war must have a reasonable chance of success, and that the means used to conduct it must be proportional to the ends sought.
     From: A.C. Grayling (Among the Dead Cities [2006], Ch.6)
     A reaction: These two principles strike me as being much more civilized and humane than Aquinas's original contribution, suggesting that in our theoretical thinking we might be making some progress.
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.
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.
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.
Just wars: resist aggression, done on just cause, proportionate, last resort, not futile, legal [Tuckness/Wolf]
     Full Idea: Classical just war theory: resist aggression; just cause must be the real reason; must be proportionate; last resort; not futile; made by a nation's authority.
     From: Tuckness,A/Wolf,C (This is Political Philosophy [2017], 9 'Ius ad')
     A reaction: [My squashed summary of Tuckness and Wolf] A very helpful list, from Cicero, Augustine and Aquinas. So where is the sticking point for pacifists? Presumably it is never the last resort, and aggression should not answer aggression.
