Study these obligations now:
On his deathbed, I promised my father to take care of the garden he planted.
Every time they ask for blood donors, I feel the obligation to go to donate blood.
Although I was alone when I found the wallet, I have an obligation to return it.
We all have an obligation to take care of the environment.
Who imposes these obligations upon us? To whom do we have these obligations?
When can we escape from them? What are the consequences of not complying with them?
Faced with the obligations imposed by others (other people, the society, the authorities), there are also obligations that we put on ourselves (they are self-imposed). This is one of the two essential conditions of moral obligations.
What are our moral obligations? How to know what our moral obligations are?
Kant's answer is related to the time in which he lived. Kant is an Enlightenment thinker. The 18th century is called "The Age of Enlightenment" because in the 18th century the light of human reason is relied upon to illuminate humanity's path towards progress. This confidence in human reason means that our moral obligations cannot be imposed on us:
Quite the contrary, our moral obligations have to be:
Our own : we impose them on ourselves. They are obligations that arise from the will of each one.
Rational : they are the result of rationally analyzing our options. And human reason is one, the same for all people.
If our obligations have to come out of our own reason, then we have to put aside personal benefit (selfishness) and the likes of each one (inclinations). This agrees with the above: goodwill excludes selfishness and personal taste.
In addition, if we took into account personal interests and preferences, then the obligations of each of us would be different from those of others, each would have theirs. That is why the second fundamental characteristic of moral obligations is that they have to be universal: the same for all rational beings. If we base ourselves solely on reason, the obligations will be common to all rational beings, that is, they will be the same for all of us.
Therefore, the key to knowing what our moral obligations are these two characteristics:
Moral obligations arise from our own will, we autoimpose them upon us.
Moral obligations are universal, the same ones for everyone. When we think we are acting morally right, we want all people to act like us.
When we ask ourselves whether we should carry out a certain action or its opposite, for example if we can give an excuse when it suits us or if we should not do so, Kant proposes the following way of reasoning :
Imagine first that we all took the first alternative: make excuses whenever you want.
Imagine then that everyone took the second alternative: never make excuses.
Now reason about the possibility or the impossibility of both alternatives:
if both alternatives are impossible, then you cannot choose either.
If one of them is impossible, then you are morally obliged to choose the other alternative.
If both alternatives are possible, then you are not morally obliged to follow either of them, it is not a moral decision. Perhaps there are other types of obligations or pressures on this decision, but it is not of a moral obligation.
Examples of moral reasoning
Example 1: Lying to get out of a hurry or not telling lies even if it suits you.
Let's imagine that no one lied when they were in a hurry. It is difficult for this to happen because we are all inclined to lie, but it is possible that this will happen.
Imagine that we all lied whenever we were in a hurry. In that situation, no one would believe anyone who was in a hurry, because we would all think "if I were in the same trouble, I would also lie." Therefore, it is impossible for all of us to lie, since the lie loses its purpose.
In conclusion, the only possible option is not to lie to get out of a hurry. We are morally obligated not to lie in a pinch. If we lie, we will not be doing our duty.
Example 2: Wear your hair long or wear it short.
Let's imagine we all had short hair. We may not like it (or we do), but this may happen.
Let's imagine that we all had long hair. We may not like it (or we do), but this may happen.
Since both options are possible, it is not a moral obligation to do one or the other, both are morally allowed according to Kant's theory.
Kant's ethical theory shows that, starting from the principle that moral obligations must be universal, they must be able to be followed by all of us, we can deduce many concrete moral obligations.
In general, we can reason and show that moral obligations (that is, obligations that we should place on ourselves) are all those that prohibit us from taking advantage of others for our own benefit, such as:
To lie
Steal
Falsify
Enslave people
Defraud the Treasury
All these concrete obligations respond to a general principle that Kant expresses in different ways, although he understands that they all express the same idea:
The categorical imperative
What is an imperative? An imperative is an order. But if we talk about morals, we are talking about orders that a person gives to himself . That is, we order ourselves to do certain things.
What does "categorical" mean? Something is categorical when it is not "hypothetical." And something is hypothetical when it includes a hypothesis or condition . For instance:
I must eat less if I want to lose weight. I mean, if I don't want to lose weight, I can eat as much as I want. Only those people who accept the condition of wanting to lose weight have to eat less.
I must not be late if I want to keep my job . I mean, if I don't want to keep my job, I can arrive any time I want. Only those people who accept the condition of wanting to keep their job have to worry about their arrival time at work.
Thus, a hypothetical imperative is an order that includes a condition: only those who accept the condition included in the imperative must obey the order.
However, a categorical imperative has no conditions. These are orders that a person gives himself without setting any initial conditions:
I must try to help others. Regardless of the situation, of whom you ask for help, of the possible benefit that you get. I must try to help.
I must not have slaves. Regardless of the time and the country in which I live, how I treat them, the possible benefit that I get. I must not have slaves.
Earlier we said that moral norms are norms that must be valid for all people. Regardless of the particular conditions of each one of us, the moral standards must be the same for all. Therefore, moral norms must be expressed as categorical imperatives. This is why Kant sums up his theory of moral norms like this:
Act in such a way that you can want that every rational being to act the same as you.
Since talking about hypothetical and categorical imperatives is complex and potentially confusing, and since Kant wants his message to reach everyone, he sometimes expresses his theory in other words: means and ends.
Something is a means when it is an instrument, an intermediate step towards something we really want, the end, the goal. Sometimes we can use a person as a means to our ends. For instance:
Win the friendship of my partner to get him to lend me his mobile. I am using my partner as a means to the end I really want: mobile.
Be nice to my neighbor to get his help later. I am using my neighbor to get his help.
These behaviors are not typical of someone who deserves to be called a good person. Using other people for personal gain is, according to Kant, a sign that we are acting immorally. For this reason, Kant also sums up his ethical theory in other words:
Do not treat others as a means to your purposes, but as ends in themselves.
Do not use others for your own benefit.
Justification of this general principle
Imagine that we all try to take advantage of others for our own benefit. If we all have that intention, who could we take advantage of? No one would be used because we would all be trying. Therefore, it is impossible for all of us to try to take advantage of others. It is a contradiction to want to take advantage of others and pretend that this is the norm that we all must follow. The alternative of not taking advantage of others is the only alternative from a moral point of view.
With these reasoning, Kant shows us a way of reasoning to know what our moral obligations are. Naturally, knowing what our moral obligations are is not the same as fulfilling them: we remain free and each of us must decide whether to fulfill them or whether we prefer to take advantage of others when we have a chance.
