Divine Command Theory, for example, argues that what’s good, and what’s not, are determined by a deity, whether that’s the God of Abraham, or a panoply of gods who come up with ethical rules by committee. And the Theory of Natural Law, as advanced by Thomas Aquinas, says that morality comes from us but only because we were made by God, who preloaded us with moral sensibilities. But many other thinkers have argued that humanity’s moral code doesn’t come from some supernatural force. 18th century German philosopher Immanuel Kant, for one, thought religion and morality were a terrible pairing, and if anything, the two should be kept apart. Instead, Kant argued, in order to determine
what’s right, you have to use reason. And a sense of consideration for other people. And – at least the way I’m teaching it
today – chom-choms. [Theme Music] Kant took morality pretty seriously, and he thought we should, too – all of us – regardless of our religious beliefs, or lack thereof. Because, he knew that if we look to religion for our morality, we’re not all going to get the same answer. But he thought morality was a constant, in
an almost mathematical sense. Two plus two equals four, whether you’re
a Christian, Buddhist, or atheist. And for Kant, the same went for moral truths. But he made a distinction between the things we ought to do morally, and the things we ought to do for other, non-moral reasons. He pointed out that, most of the time, whether or not we ought to do something isn’t really a moral choice – instead, it’s just contingent on our desires. Like, if your desire is to get money, then
you ought to get a job. If your desire is get an A in class, then
you ought to study. Kant called these if-then statements hypothetical
imperatives. They’re commands that you should follow
if you want something. But hypothetical imperatives are about prudence,
rather than morality. So, if you don’t want money, you can always
choose not to work. And if you don’t care about getting a good
grade, studying becomes totally optional! It’d be a terrible option, in my opinion
as an educator, but still: optional. But Kant viewed morality not in terms of hypothetical imperatives, but through what he called categorical imperatives. These are commands you must follow, regardless
of your desires. Categorical imperatives are our moral obligations, and Kant believed that they’re derived from pure reason. He said it didn’t matter whether you want to be moral or not – the moral law is binding on all of us. And he said you don’t need religion to determine what that law is, because what’s right and wrong is totally knowable just by using your intellect. OK, so how do you figure out what’s moral? Kant said the categorical imperative can be
understood in terms of various formulations. Basically, different ways of phrasing or looking
at the same essential idea. And he came up with four formulations of the
categorical imperative. Let me tell you about the two most popular
ones. The first formulation of the categorical imperative
is often known as the universalizability principle. And Kant phrased it this way: “Act only according to that maxim which you can at the same time will that it should become a universal law without contradiction.” OK, Kant. Pretty wordy guy.
So let’s unpack what he was saying. A maxim is just a rule or principle of action. And a universal law is something that must
always be done in similar situations. So, as a Kantian, before I act, I would ask
myself, what’s the maxim of my action? In other words, what’s the general rule that stands behind the particular action I’m considering? Let’s say you forgot your wallet in your
dorm this morning. You don’t have time to go get it between
classes, and you’re really hungry. You notice that the student working the snack kiosk in the union is engrossed in a conversation, and you could easily snag a banana and be on your way. Sorry. Chom-chom.
I mean: chom-chom. You could easily swipe that chom-chom and
be on your way. Is it ok, morally, for you to do this? Well, the particular action you’re considering – taking a chom-chom from a merchant without paying for it – is stealing. And if you approve the maxim of stealing – which you’re doing, whether you admit it or not – then what you’re actually doing is universalizing that action. You’re saying that everyone should always
steal. If you should be able to do it, then – everyone
should be able to do it. The thing is, this leads to a contradiction
– and remember: Kant’s wording specifically says that moral
actions cannot bring about contradictions. The contradiction here is: no one would say
that everyone should steal all the time. Because, if everyone should always steal,
then you should steal the chom-chom. And then I should steal it back from you, and then you should steal it back from me, and it would never end and no one would ever get to eat any chom choms. Therefore, stealing isn’t universalizable. So what Kant’s really saying is that it’s
not fair to make exceptions for yourself. You don’t really think stealing is ok, and by imagining what it would be like to universalize it, that becomes clear. Now, Kant’s view that moral rules apply
to everyone equally sounds nice and fair. But it can sometimes lead to some pretty counterintuitive results. To see how this formulation can go awry, let’s
visit the Thought Bubble for some Flash Philosophy. Let’s say, one morning, Elvira and Tony
are having breakfast. Then a stranger comes to the door and asks
where Tony is, so he can kill him. Obviously, Elvira’s impulse is to lie, and say that Tony isn’t around right now in order to protect him from this would-be murderer. But Kant says that she can’t lie – not
ever, not even to save Tony’s life. Here’s his reasoning: Suppose she’s at the front door, talking
to the stranger. At the time, she thinks Tony’s in the kitchen,
where she left him. But it turns out he was curious about the caller, so he followed her into the living room, and heard the stranger make his threats. Fearing for his life, Tony slipped out the
back door. Meanwhile Elvira, in her desire to save him, tells the stranger that Tony isn’t there, even though she thinks he is. Based on her lie, the stranger leaves, and runs into Tony as he rounds the corner heading away from the house, and kills him. Had she told the truth, the stranger might have headed into the kitchen looking for Tony, which would have given Tony time to escape. But she didn’t. Now, by Kant’s reasoning, Elvira is responsible
for Tony’s death, because her lie caused it. Had she told the truth, only the murderer would have been responsible for any deaths that might have occurred. Now, she could have refused to answer the
stranger altogether, or tried to talk him out of it. But the one thing she is never permitted to do is violate the moral law, even if others are doing so, even for a really good cause. Poor Tony. Very sad.
But thanks, Thought Bubble! So, the first formulation of the categorical imperative is about the universality of our actions. But the second formulation focuses on how
we should treat other people. And it goes this way: “Act so that you treat humanity, whether in your own person or in that of another, always as an end, and never as a mere means.” Again, we have to define some terms here to
figure out what this is all about. To use something as a “mere means” is to use it only for your own benefit, with no thought to the interests or benefit of the thing you’re using. Now, we use things as mere means all the time. I use this mug to hold my coffee, and if it would stop benefiting me – like if it got a crack in it and started leaking, I wouldn’t use it anymore. It’s perfectly fine to use things as mere
means – but not humans. This is because we are what Kant called ends-in-ourselves. We are not mere objects that exist to be used
by others. We’re our own ends.
We’re rational and autonomous. We have the ability to set our own goals,
and work toward them. Coffee mugs exist for coffee drinkers. Humans exist for themselves. So, to treat someone as an end-in-herself means to recognize the humanity of the person you’re encountering, to realize that she has goals, values, and interests of her own, and you must, morally, keep that in mind in your encounters with her. Now, Kant pointed out that we do use people,
all the time, and that’s ok. Because, most of time time, we use other people
as a means for something, but not as a mere means. We still recognize their humanity when we
use them, and they agree to being used. So, for example, you are using me right now
to get information about Kantian ethics. I am using Nick and Nicole to help me get
that information to you. Kant said that you and I, and Nick and Nicole – we all we deserve to not be used as mere means, because of our autonomy. Unlike other things in the world, we’re
self-governed. We’re able to set our own ends, to make our own free decisions based on our rational wills. We can set goals for ourselves, and take steps
to realize those goals. This imbues us with an absolute moral worth, Kant said, which means that we shouldn’t be manipulated, or manipulate other autonomous agents for our own benefit. And this means that things like lying and
deception are never OK. Because if I’m being deceived, I can’t make an autonomous decision about how to act, because my decision is based on false information. For instance, I might agree to loan you money so you can buy books for school, but I wouldn’t agree to loan you money so that you can get a new Xbox. I’m sorry, but no. So when you lie to me about what you’re gonna be doing with the money you’re asking for, you rob me of my ability to autonomously decide to help you. You’ve treated me as a mere means to accomplish your goals, with no thought to my own goals and interests. And that’s a violation of Kant’s second
categorical imperative. So! Kant argued that proper, rational application of the categorical imperative will lead us to moral truth that is fixed and applicable to all moral agents. No God required. Of course, not everyone agreed with him. So next time we’re going to check out a theory that is in many ways the antithesis of Kantianism: utilitarianism. Today we learned about Kant’s ethics. We talked about hypothetical and categorical imperatives, the universalizability principle, autonomy, and what it means to treat people as ends-in-themselves, rather than as mere means.

I don't see the example of the murderer as a sound refutation.
If we remember that Kant wants us to think of morality as equal to e.g. physical laws, then the murderer, by virtue of wanting to be murderous, has broken the fabric of moral reasoning. Therefore, any choice making that follows from that isn't logically grounded anymore. It's as if the murderer has flipped gravity and then expects you to logically build something while sticking to the usual way in which gravity works.
Why do you guys post these here, just so the sub has something to tear apart?
Did he call natural law supernatural?
Salay plz explain. Or at least ask your sister.
Wish I'd found this before I took my exams :')
What if I say that my maxim is "check all these statistics about the world and do the most utilitarian thing possible?"
Is that universalizable?
Can I say that "I can lie, if I tell everyone involved the truth later, and if I am fairly sure that the lie will cause good otherwise."?
I don't think it makes sense to completely respect murderer's own moral judgement, because it could be mental illness or something, and it's important to respect the victim's moral judgement.
Does "mere" means happen when the person didn't consent to being means? What if I could give 10,000 people freedom with one non-consenting person, by secretly using them in a trivial way?
Is the universalizability principle a formulation of the Golden Rule?
