I tell you what, when I started my philosophy journey I really did think philosophy books were going to be closer to mystical self-help guides than they really are. The average polymath white dude Thinker TM of the last few centuries produced a work that’s a combination of apologetic letter to the sponsors for the gap in content, grammatical lexicon (what are words?), and legal statement. There’s a whole swathe of this book that’s all about wills, are they legal? It felt like a chapter of a lawyer’s textbook had been printed by mistake. But that’s OG text philosophy for ya! The ‘good life’ involves listening to God pronounce the judgements of your conscience court, not being happy about colonialism but finding the extermination of illegitimate kids tolerable, and wondering if haircuts are self-mutilation. Fun times.
Here be my notes.
Preface
There’s only one human reason, and so only one philosophy, one virtue, and one doctrine of virtue.
A doctrine’s ability to withstand ridicule signals its truth.
Introduction to the Metaphysics of Morals
Science has a priori principles.
Morals hold if they are SEEN to be based on a priori morality, not experience.
Only experience teaches us what brings joy; it cannot be reasoned beforehand.
Reason commands how to act without examples; its authority is based on purported advantages.
Moral anthropology deals with conditions that hinter or help in fulfilling the metaphysics of morals. It should not be confused with them.
Pleasure is a subjective feeling; it is only in relation to the subject.
Pleasure that precedes desire is inclination. Desire that precedes pleasure is intellectual pleasure.
Choice is the ability to fulfil a desire. A wish is an inability to fulfil a desire.
The will is the faculty of desire that lies within reason.
Choice isn’t pure but can be determined by the will.
Freedom is a purely rational concept; it cannot come from any possible experience.
Moral laws are imperatives; actions are either permitted or forbidden.
A fault is an unintentional transgression, while a crime is an intentional transgression.
Justice dictates right according to external laws.
Natural laws exist a priori and are obligatory without external lawgiving.
The categorical imperative says that you must act upon a maxim that can also hold as a universal law.
Legality is the conformity of an action with the law of duty.
Morality is the conformity of the maxim of an action with a law.
A maxim is a subjective principle of action and a principle of duty. Reason prescribes how you ought to act.
A law has a proposition that contains a command.
A priori binding laws come from a supreme lawgiver.
There is more merit if great natural obstacles and less moral obstacles block your actions.
Keeping promises is a duty of right not virtue, as this can be coerced.
Introduction to the Doctrine of Right
The doctrine of right are laws for which external lawgiving is possible.
A positive right exists if there has been actual lawgiving about it.
Right has to do with people’s relations to each other: choices not wishes.
Any action is right if it can coexist with everyone’s freedom in accordance with a universal law.
Everyone must pay debts: this is a coercion that coexists with the freedom of all.
The doctrine of right wants to be sure what belongs to all has been determined, while the doctrine of virtue has space for exceptions.
Thread of an uncertain ill (capital punishment) isn’t outweighed by a certain ill (drowning).
The duties of right are: be a means and an end for others; do not wrong anyone; let others keep their stuff.
Rights are: natural and a priori; positive/statutory if legislated; innate if belonging to everyone; acquired if it requires an external action.
Freedom is an innate equality which is beyond reproach.
The duties of right can have lawgiving while the duties of virtue cannot.
We know our own freedom through the moral imperative.
The moral imperative commands duty, from which you can then derive the capacity to put others under obligation.
Our relations to other humans involve rights and duties; to animals no rights or duties; to god, only duties, no rights.
The state of nature is not opposed to social but to civil conditions.
Private Right
If something is rightfully mine, I would be harmed if it used without my consent. This is called possession.
Rational possession is of an object external to me.
Empirical possession is of an object in another location.
Intelligible possession: I’m not holding it, but it’s still mine.
Do I possess another’s choice? Is his promise included in my belongings, independent of temporality or empirical possession?
Rights are a priori propositions sine they are laws of reason.
Permissive law is where others cannot have my stuff because I got there first.
Intuition re: empirical possession must be removed in order to extend the concept to: ‘it’s mine if I control it’.
Empirical holding v the concept of possession.
That is mine which I bring under my control, can use, and will to be mine.
Property Right
You don’t own things; otherwise you’d be their guardian spirit and have an obligation to objects.
The right to a thing is actually the right to the private use of a thing that’s originally owned in common, against others who also possess it in common.
The original possession in common precedes any acts of establishing rights.
Acquisition of an object is by unilateral will. However the capacity of the common will to bind recognition of possession is valid even if unilateral.
The condition in which the will of all is united for law is the civil condition.
Coercion is necessary to leave the state of nature for the civil condition, which makes acquisition provisional not conclusive. Provisional acquisition needs law to determine its limits. Leaving the state of nature is based on duty.
Kant is against colonialism!
If I am wronged, I can demand what is mine but not more.
Under a promise, you are enriched by an obligation on the freedom of another person.
Rights of Persons
Sexual union is the reciprocal use of sex organs. It can be natural or unnatural (!!).
Marriage is in accordance with law.
Sex work is making yourself a thing.
Husbands are the natural superiors in promoting the household’s interest … lol.
Children have an innate right to care. They are made without their consent, on their parents’ initiative. Thus the parents have an obligation to make the child content. You cannot destroy a child like a piece of property.
Division of Rights acquired by Contract
Division according to a priori principles is dogmatic
Money represents all goods. It is only indirect.
The nation’s wealth is the sum of the industry humans pay each other.
On Acquisition
A contract to make a gift should not be coerced.
If you loan something and its damaged, you are liable unless you specifically said not to do that beforehand.
You can never prove who first owned a thing, thus there’s no such thing as a ‘secure’ acquisition.
How do you know oaths are real? By presuming religion is real and relying on spiritual coercion.
Public Right
Individuals living in a civil condition is a state.
The difference between this and the state of nature is that laws for distributive justice can be put into effect.
The legislative authority of the state only belongs to the united will of the people.
A legislator cannot be a rule because the ruler is subject to the law.
There cannot be an authority to resist a supreme leader because that would make resistance stronger than the supreme leader so he isn’t supreme any more. Thus a state has no right to rebel. Reform can only be introduced by a sovereign. If a king is overthrown you can’t blame him for any acts he did as a supreme leader because he was the supreme law at the time.
By killing a king the state commits suicide, a truly unforgiveable act.
The government is authorized to constraint the wealthy to help maintain those who aren’t.
He suggests taxing childless people to support orphans! Thank you next.
Churches cannot hinder progress as this is anti-humanity.
You cannot bequeath merit to your descendants (anti-hereditary nobility yay).
Laws of punishment should not teach lessons or cause reparations: just punish the crime. Nor should punishment involve experiments. Justice isn’t justice if it can be bought.
Apparently an honourable man would prefer to be hung for murder than do hard labour – it would be more punishing to live and do hard labour.
Illegitimate children are like contraband that’s smuggled into the country! You can ignore their ‘annihilation’!!!
The overthrow of a civil constitution by revolution is a dissolution of democracy, because the united people are the sovereign.
The Right of Nations
The rights of states are all about war.
All states are in a condition of war with others at all times.
Apparently wars can’t be punitive, or carried out for extermination or subjugation. Er, what?
Cannot use in your state’s defense: spies, snipers, assassins, fake news, or plunder.
States have no right to seek compensation or make colonies after a war, because that suggests the war was unjust.
You can take any measures against an unjust enemy … but what is an unjust enemy?
Perpetual peace is unachievable. However, even so, we should act like it is and work towards it.
Cosmopolitan Right
Marriage is a way of preventing sex from being dehumanizing.
Children incur obligations from their parents.
Power should belong to laws and not humans; this is what metaphysics is.
Doctrine of Virtue
Ethics are duties that don’t come under external laws.
Duty is a constraint, either external or self imposed.
Virtue is the capacity and resolve to withstand an unjust opponent.
Ends that are also duties: one’s own perfection and the happiness of others.
Adversity, pain, and want are temptations to violate duty.
The greatest perfection is to do your duty from duty.
Benevolence is unlimited; it is harder to do good.
Self love can’t be separated from our need for love, hence we make ourselves an end for others.
There are no limits to what we should do for others; we definitely shouldn’t tempt them to do things that will later pain them.
Strength of virtue is measured by the obstacles overcome.
Obstacles include our natural inclinations, so constraint is self imposed.
The unconditional end of virtue is to be its own end and its own reward (versus holiness, because a holy person is never tempted).
We can enhance the moral incentive by contemplation.
Moral feeling is an awareness that our actions are constrained by duty; it isn’t created but cultivated.
Conscience is an unavoidable fact, but it is possible to ignore its verdict. We can work to enlighten ourselves as to what is our duty.
Through doing good to others you may learn to love your neighbour ‘as yourself’.
Respect for your own being forms the basis of your duty to yourself.
Duties to Oneself
Suicide goes against the duty of self preservation and violation of one’s duty to others.
Self mutilation is also undutiful. (Depends if you’re ill though, and he’s unsure about haircuts. Also vaccines.)
‘Unnatural’ sex is worse though because suicide requires courage and some self-respect, but bad sex deprives you of ALL RESPECT.
Is having sex with an infertile woman morally wrong, Kant wonders.
Sexual pleasure is not moral pleasure.
Gluttony and drunkenness basically make you an animal (weirdly I am on board with this hot take).
Perfect Duties to Oneself
Regarding lies: the doctrine of right says they’re only harmful if they hurt others. Ethics says no authorization is derived from harmlessness.
An external lie is contemptible to others, an internal lie is contemptible to oneself.
Conscience is an internal court. You can refuse to heed it but not to hear its verdict. God is the judge.
God doesn’t provide an empirical experience and we should act as if he exists.
Imperfect Duties to Oneself
Duty to cultivate natural powers. The powers of the spirit are exercised through reason not experience eg maths. The powers of the soul are memory and imagination. The powers of the body is looking after the body’s matter.
Duties of Virtue to Others
Love is a benevolence that results in beneficience.
Respect is limiting our self esteem by the dignity of others.
Sympathy is pleasure at another’s joy.
Envy is greeting another’s wellbeing with distress.
We have a duty to respect every human being and that is why torture is bad.
Failure to do so is vice.
The Methods of Ethics
A good example isn’t a model; it shows us what we ought to be.
A Stoic puts up with misfortune and learns how to do without superfluous pleasure.
An Epicurean has a cheerful heart.
Doing duty is meritorious only if done cheerfully.
Ethics cannot extend beyond the limits of humans’ duties to each other; God is too complicated to count.
