Question 1What exactly is the “ability to think for oneself”?
I'm amazed at how once I research something on Instagram or YouTube, it's immediately reflected in advertisements and the like. Even when I shop, I feel like I'm unconsciously influenced by those advertisements, and my decisions are merely influenced by those around me. On the other hand, since entering university, I've often been told to "gain the ability to think for myself," but what kind of ability is this in the first place?
Myself? Surely there is no such entity?

The philosopher who answers
A staunch skeptic who disagrees with trends
David Hume
(England / 1711-1776)
The issue with this question is what it means to "think" for oneself. This is a major theme in philosophy, so let's explore it carefully.
French philosopher Descartes established the famous idea of "I think, therefore I am" as the starting point of modern philosophy. This theoretical thinking, which prioritizes the "thinking self" and starts from the "100% pure self," has led science and society to the present day. This is why adults are constantly chanting, "Develop the ability to think for yourself."
The British philosopher Hume disagreed with this idea that had existed since Descartes. In his book "A Treatise of Human Nature," he boldly pointed out that the mental entity that we tend to imagine as the "thinking self" is nothing more than a "bundle of perceptions." He argued that what constitutes us is information (perceptions) obtained through our eyes, ears, etc., and that the idea of a self as an entity not based on such things is something like a fiction.

This word "substance" is an important term in philosophy, and means that something exists without depending on anything else. In other words, Hume thought that "there is no such thing as an untainted self." In response to the questioner's question, he would answer, "The cause of our worries is the preconceived notion that there must be a brand new 'self'." Indeed, when we get down to it, we repeat our thoughts every day, influenced by language, culture, the family and region we grew up in, and so on. It's impossible to say that there is a "100% pure self."
So I think the questioner doesn't need to be so worried about thinking for himself. Perhaps he wants to protest the contradictions of modern society, where adults who don't think for themselves, or who don't really want people to think for themselves, educate us to "think for ourselves." In such a case, Hume's ideas may be a strong ally.
Question 2II want to be “someone” rather than just one of them.
I strongly feel that I want to become someone in the future. On the other hand, I am sometimes tempted to take the easy option of being myself. I also have a vague fear of dying as an ordinary one of them. Who should I become in this big world?
You are already "someone."

The philosopher who answers
A gentle Indian philosopher who opposes violence
Amartya Sen
(India / 1933-)
The "ordinary one of them" that the questioner refers to can also be said to be a state of losing one's identity. Let's consider the issue from the perspective of the word "identity."
Identity is a philosophical term meaning "sameness." The dictionary definition is that an individual maintains unity and uniqueness in the face of change and difference. We use the word identity in our daily lives, but there is an image that "each person has one identity." This is probably also influenced by the dictionary definition of "self-identity."
However, modern Indian philosopher Sen looks at identity from a slightly different angle. A Nobel Prize winner in economics who has also tackled issues such as poverty and violence, in his book "Identity and Violence", he uses identity to mean "identity with others". As opposed to "self-identity", "identity with others" seems quite strange, doesn't it? However, Sen's idea is that we have various "identities" with others, and we live at the center of these overlaps. You may be able to understand it if you put yourself in his shoes.
You all have multiple characteristics, such as being enrolled at Waseda University, participating in student club activities or part-time jobs, and your home country or region. The same goes for hobbies, gender, place of residence, etc. And each of these characteristics is shared by other people too. You are not the only Waseda student, right?
What was revolutionary about Sen was that he considered the overlapping of characteristics to be "individuality." And he said that the more characteristics there are and the more complex one's characteristics are, the more distinct one's individuality becomes. For example, Goethe, the man of letters, was a poet, but also a politician, natural scientist, and painter, and possessed a variety of characteristics. If Goethe were to disappear, there would be no one else who could do the same things. That is why other philosophers have argued that Goethe was individualistic.

Try applying Sen's theory of identity to yourself. The person asking the question already has many different identities and is already "someone." However, I'm sure you will not be satisfied with this answer (laughs). So I can give you two suggestions for what to do. The first is to get involved in as many things as possible and expand your range of activities. In other words, increase the number of characteristics that become your identity. The second is to strengthen your characteristics, that is, to spend time on things that you are passionate about and have a strong interest in. Dig deep into one of your many identities. This will open up new paths for you and allow you to become a powerful "someone."
Question 3: How should I deal with unfairness that arises in interpersonal relationships?
At my part-time job, I often get told off because there are people who don't follow the rules. I feel it's unfair. On the other hand, I sometimes get angry at others, and I worry that if I lose my temper, I will also become an unreasonable person. How should I deal with such situations? I would like to learn how to think about it.
Let's deal with the unreasonable things that happen in reality in the real world.

The philosopher who answers
A realist who values steady progress
Georg Wilhelm Friedrich Hegel
Georg Wilhelm Friedrich Hegel
(Germany / 1770-1831)
Generally speaking, we feel that something is unreasonable when it is something that goes against our ideals and does not make sense in the real world. In that respect, the questioner has an idealistic perspective. Here, the ideas of the realist Hegel can be helpful. His perspective may bring about a change in our way of thinking.
First, I will talk about the two major streams of thought that have existed in the world of philosophy since ancient times: idealism and realism. Idealism says, "If there is a gap between ideals and reality, then let's strive for the ideal." Representative figures of this school are Plato of ancient Greece and Kant of modern Germany. For example, Kant is a believer who thinks, "Even if there was no person in the world who never lied, humans still should not lie."
Realism, on the other hand, says, "Because anger occurs in the real world, the reasons for it are also real. Let's face it in reality." The German Hegel is a prime example of this. He was active after the French Revolution, a time when the whole of Europe was burning with idealism. At that time in France, a young man became angry and stabbed a poet suspected of colluding with Russia to death. Elimination is an extreme example of idealism, moving from an unreasonable reality to an ideal world, but at the time a growing number of people in France defended the young man. However, Hegel dismissed French public opinion as shallow. He argued that people should not resort to terrorism such as elimination, but should have confronted why problems like espionage suspicions arise and sought solutions in reality.
His famous words are, "The rational is the realistic, and the realistic is the rational." Based on this idea, he placed importance on the attitude of improving the unreasonableness without denying reality itself. He did not think of reality and ideals as separate.

If we don't get angry when something unreasonable happens, the world will not improve. For example, we can now talk about harassment as a social issue because there were people who got angry and spoke out in the past. On the other hand, things will not move forward if we only hold up our own ideals and do not face realistic solutions. Hegel teaches us this perspective. First, we must thoroughly explore the reasons why we are angry, and then improve the world through real human relationships, such as dialogue, negotiations, legal action, and elections. I think this approach is important.
Question 4Why does war never disappear from the world?
Conflicts continue to occur in the world, including Ukraine and Palestine. Despite the horrific wars that humanity has experienced in the past, why is it that world peace has not yet arrived, even in the 21st century? Is it impossible for all people in the world to get along with each other?
Does everyone getting along really lead to peace?

The philosopher who answers
An idealist who stood up for human rights
Immanuel Kant
(Germany / 1724-1804)
War and peace are the most important themes for humanity, but the point we should consider when asking this question is whether "everyone getting along" is really a condition for peace. Kant, who was mentioned earlier, gives us a hint this time.
Kant, who built the foundation of modern philosophy with his thorough logic that does not allow for contradictions, wrote a book called "Perpetual Peace" in his later years. "Perpetual peace" is a state in which there is no possibility of war ever happening again. To achieve this, he discussed not respecting the spirit of philanthropy such as "everyone getting along," but the "rights" that guarantee freedom. What does this mean?
Rights mean that "what is mine and what is yours are different." When someone tries to take something away from you, you say "no," right? The reason "everyone gets along" is not good is because the boundary between "mine" and "yours" can become blurred before you know it, and someone will try to take advantage of that situation and take away rights. Kant believed that freedom is at the very foundation of rights. He said that the distinction between "my freedom" and "your freedom" is at the core, and that various other rights exist on top of that.

In order to guarantee individual freedom, we first need a nation and laws. However, even if rights are protected within a country, the possibility of them being violated by other countries in the event of war cannot be ruled out. This is why we need international law, where nations can guarantee each other's rights. Kant believes that this is how perpetual peace will be realized.
It's a fairly systematic philosophy, but what's noteworthy is that it doesn't rely on "friendship" or "philanthropy." Even today, we see cases where countries launching wars of aggression invoke philanthropy, such as "saving our fellow man." Kant must have understood the danger of this.
Imagine this Kantian perspective. A conflict is occurring in a foreign country, the human rights of someone on Earth are being violated, and everyone is turning a blind eye to it. Living in such a world means that one day, your own human rights violations will also be overlooked. That's frightening.
Issues surrounding rights are occurring even in modern Japan, where there is currently no war. If we truly desire world peace, shouldn't we first pay attention to and confront the issue of rights that is close to us? If each individual deals with the problems in front of them and things proceed along the lines of a proper democracy, human society as a whole should also progress. Humanity repeats contradictions, and the day when there will be no wars at all may never come. Even so, we must not despair, but think about the way forward. Kant himself spoke courageously about human rights, saying, "We are all human beings," in an era when there was war, colonial rule, and slave trading. We who live in the modern age should have a lot to learn from Kant's attitude.
Question 5: I don't know what use my studies at university will be.
Even though I study at university every day, I can't imagine how it will be useful in the future. I can understand academic subjects that are directly useful for business, such as languages and programming, but I can't see the meaning in many academic subjects. In the first place, I wonder if universities have any reason to exist in society.
What you learn at university doesn't have to be useful

The philosopher who answers
A 20th century giant who philosophized about philosophy
Karl Jaspers
(Germany / 1883-1969)
In his book "The Ideals of the University," the 20th century German philosopher Jaspers argues that at the core of university learning is a "fundamental desire for knowledge." To put it in one word, it is a rather nerdy desire to "know, not for any other reason" (laughs). According to him, academics do not have to be useful in life or business. However, "The Ideals of the University" is still highly regarded as an exemplary theory on universities. Let's consider the significance of universities and academics from his perspective.
The question "What is the significance of the existence of universities in society?" is similar to the question "What is philosophy?" Imagine the world as a tree. Academic fields related to cutting-edge technology and social activities are the branches and leaves. They progress every day, growing toward the sunlight. A characteristic of these academic fields is that the results are the "answers" to "questions" such as "What is the optimal system for improving welfare?", "Why do earthquakes occur?", and "When will deflation end?".
But sometimes, we go back to the trunk or roots of the tree and ask ourselves, "What is happiness, even before we consider welfare?" This is philosophy, which is characterized by the reverse route from "answer" to "question." We can answer the question, "What time is it now?" by looking at the clock, but we delve into areas where we don't even know if the answer exists, such as, "What is time anyway?" You can't do this unless you have a lot of free time (laughs).
The role of universities is also like the trunk of a tree. Society, on the other hand, is the branches and leaves. For example, companies develop new products and cutting-edge technologies by focusing on activities in various areas such as IT, automobiles, finance, and welfare. However, as the branches and leaves continue to evolve, they also encounter challenges. For example, today, with the rise of generative AI, the question of "what role should humans play?" comes into question, and there comes a time when we must return to the roots. The same goes for economic disparity, the environment, and human rights issues. This is when the role of universities in society will be demonstrated.

If the questioner becomes a businessperson in the future, he or she will certainly pursue profits. However, one day, he or she will ask themselves, "What is the purpose of this pursuit of profit?" and answer, for example, "For the happiness of people." If we go even further, the question of "What is happiness?" will also arise. Even in the course of society, the "fundamental desire for knowledge" will not disappear. As the ancient Greek philosopher Aristotle wrote, that is what humans are. And as long as we do not stop thinking, I believe that universities, learning, and philosophy will not disappear either.
Getting into the habit of thinking from the roots will dramatically change the way you see the world
We've delved deeper into your questions with the perspectives of five philosophers.
Philosophy is an attempt to endlessly question and think for yourself. If there is anything beneficial for you, I think it is rather the process of thinking itself. If you get into the habit of thinking from the trunk or root of the tree, your horizons will undoubtedly be greatly broadened. If you think for yourself about small everyday events, your current field of expertise, your future career development, and even the act of reading novels or philosophical books, a completely different world will open up to you. Don't try to find an answer right away, but look at things calmly from various angles. And take advantage of the university environment and think things through thoroughly. Philosophers from all over the world, past and present, will be there for you and give you hints.

Welcome to the world of philosophy. Many students avoid philosophy because of its difficult image. Is this because they are forced to memorize ethics and world history in high school? Until high school, students focus only on "who said what," but in real philosophy, the most important thing is "what questions you ask." It is an activity in which you dare to ask questions directly to themes that seem obvious. Therefore, it is actually a highly flexible academic field that anyone can tackle just by thinking.
I will now introduce five questions sent in by Waseda University students. They all posed sharp questions, which is enough to be considered a subject of philosophy. This time, we will delve deeper into simple questions through the philosopher's analysis, but compared to general problems and concerns, you may feel that "there is no clear-cut solution presented!" However, the lack of answers is what makes philosophy interesting. Let's get started.
