Philosophy as a Weapon — Shu Yamaguchi

I picked up this book, 'Philosophy as a Weapon,' after reading several books by Ryunosuke Fukai of Coten Radio and Shu Yamaguchi, which sparked my interest in philosophy and Yamaguchi's work.
Here are the books by Fukai and Yamaguchi.

It is a practical book that reinterprets concepts buried in the history of philosophy as tools that business professionals can use in their daily work.
Since this post is long, I will split it into two parts. First, here is the first two chapters (on 'People' and 'Organizations').

0. Summary

This book, 'Philosophy as a Weapon: 50 Key Concepts of Philosophy and Thought to Survive Life,' is written by Shu Yamaguchi, a management consultant who has been involved in corporate decision-making and organizational transformation. He presents philosophical and intellectual concepts not as 'liberal arts' but as weapons of thought that can be used in practical business.

Philosophy is often treated as a 'representative of useless academic disciplines,' but the starting point of this book is that it actually functions as a tool for business professionals to accurately gain insight into the situations before them, understand the background of irrational behavior by others or organizations, and improve the quality of their decision-making. Its greatest feature is that it does not teach the history of philosophy systematically, but rather reorganizes key concepts into a form that can be 'taken out of the drawer and used' when facing real-world challenges.

The structure consists of two parts: an introduction explaining 'why business professionals need to learn philosophy,' followed by the introduction of 50 concepts. These 50 concepts are organized into four categories: key concepts regarding people, key concepts regarding organizations, key concepts regarding society, and key concepts regarding thought. Famous concepts from the history of philosophy and thought, such as Aristotle's Logos, Ethos, and Pathos, and Hannah Arendt's 'banality of evil,' are explained alongside the perspective of 'how they can be used in business and daily life.' I think this book is suitable for business professionals who are facing situations in management or team leadership where they wonder, 'Why is this decision-making not going well?' or 'Why does the organization act this way?'

1. The Meaning of Learning Philosophy — The Danger of the Uneducated Expert

The phrase introduced at the beginning of the book, 'there is nothing more dangerous to our civilization than an uneducated expert,' left a lasting impression on me. The idea of noblesse oblige, which suggests that those in positions of power are expected to have education and ethics, has spread to ordinary business professionals who do not hold high status, now that anyone can post on social media and the internet. I believe that as more people gain influence, the responsibility to post with education and ethics has expanded accordingly.

Another interesting perspective Yamaguchi raises is that what one gains from learning philosophy is a model for critical thinking. The history of philosophy is a cumulative process where each generation has continued to cast doubt on the thinking of their predecessors, so patterns for critical thinking have accumulated there. I also felt that the book's framework of analyzing philosophers not by their
output—what they thought—but by the process—what they thought about, what questions they started from, and what background led them there—is in itself a highly educational way of breaking things down.

2. What Drives People — Logos, Ethos, and Pathos

Among the key concepts regarding people, the first one that impressed me was Aristotle's Logos, Ethos, and Pathos. This is the idea that to persuade and move people, one needs logic (Logos), ethics (Ethos), and passion (Pathos). While Logos tends to be emphasized today, the importance of Pathos is often discussed in the startup world. I think the forms required for Logos and Ethos change with the times, but I felt that Pathos is the only one that requires the same kind of energy in every era.

In addition, the paradox of Calvin's predestination—that the fact that things are 'predetermined' actually creates motivation—and the point that John Locke's tabula rasa (blank slate) leads to an attitude of always relearning from zero—what we now call unlearning and relearning—were points that resonated across time.

3. Masks and True Faces, Choosing to be Subjective

Jung's concept of the persona was thought-provoking. It is the idea that everyone wears a mask, but people lose track of where the mask ends and their true face begins. I also feel that the mask I wear changes depending on the community I belong to. Thinking that the community where I can take off my mask the most might be closest to my true self gives me a new way of seeing myself. I felt that I want to keep asking myself where I wear a mask and where I take it off, using the people around me who I think are 'always natural' as models.

Another concept that resonated with me was Sartre's engagement. It is the idea that there are no coincidences in the world and that one should proactively involve oneself in everything as if it were one's own business. Looking back at myself, I am aware that I am easily swayed by external stimuli and the cheers of others. I felt this was similar to the sense of choosing to 'not choose' discussed in Kaho Miyake's 'Why You Can't Read Books When You're Working.' I feel that being proactive, as described in the first habit of 'The 7 Habits of Highly Effective People', and making proactive choices myself is the next big challenge for me.

Another thing that made me think was Hannah Arendt's banality of evil. Using the Eichmann trial as a subject, it introduces the idea that evil is not something extraordinary caused by special people, but rather that ordinary people who uncritically accept a system are the ones who commit evil. If time passes without questioning the current system and without the ability or thought to try to change it, I think there are times when it can look completely like 'evil' from the outside when viewed in retrospect. If I don't cultivate my sense of ethics, I am likely to be dyed in the colors of the organization I belong to, so I felt that this is something I must be very careful about myself.

4. Actions create intentions — Cognitive dissonance and the responsibility of division of labor

Festinger's cognitive dissonance was also an interesting perspective. It points out that intentions do not determine actions, but rather intentions are created after the fact by actions; in other words, humans are creatures that justify their actions after the fact. There are many parts of this that I can relate to, and knowing that this has been discussed since Festinger's time not as a mere personal habit, but as a tendency common to all Homo sapiens, I feel that being able to re-examine myself as a general theory is the very meaning of learning meta-cognition and the humanities. Just like with engagement, if I can reframe it not as 'this is just how I am' but as 'this is something all of humanity is subject to,' I think I can proactively face this characteristic.

From the famous Milgram experiment, I was struck by the point that division of labor creates a passing of the buck and a dilution of responsibility. In the context of capitalism and the Industrial Revolution, division of labor has been discussed as a keyword for efficiency, but if sharing responsibilities also lightens the sense of responsibility of each individual, then I realized that if one does not approach it with a sense of ethics, there is a danger that one will only be able to see the scope of one's own role.

5. Balancing challenge and ability — Flow and management

Regarding Csikszentmihalyi's flow, among the conditions introduced in this book, I found 'immediate feedback on actions,' 'a balance between challenge and ability,' and 'distorted sense of time' to be particularly interesting. Among them, 'immediate feedback' is a keyword that is both practical and impressive, as it is also positioned as an important role in game theory. Immediate feedback and the balance between challenge and ability can be intentionally created as an environment. I think that not only for myself to enter a flow state, but

giving quick feedback to team members is a trick for management and team building that allows those around you to enter a flow state.

6. Leadership resides in context and dialogue — Machiavellianism and the devil's advocate

Among the key concepts regarding organizations, Machiavelli's Machiavellianism left an impression on me. It is a book I touched upon in MBA leadership theory, but Shu Yamaguchi's take that leadership is context-dependent was convincing once again. It's not that Machiavelli was wrong, but that it was the optimal leadership for that era, and I think the form of leadership required changes depending on the environment in which I work and live today. This topic is discussed in detail in Shu's 'Context Leadership.' I haven't posted a book review yet, so I will upload it later.

And the most interesting part this time was John Stuart Mill's Devil's Advocate. The "Devil's Advocate" was originally a traditional role in the Catholic Church.
In my work, when a discussion went in a circle and returned to the original conclusion, I used to feel that the discussion was a waste of time. However, recently, I have come to feel that the more an argument survives after being exposed to critical opinions, the more its rationale is refined and strengthened. This happens because discussions are polished within a more diverse group, so I think it is a way of thinking that is
highly compatible with diversity and GI. Even in the 1-on-1 meetings I have been consciously holding recently, I have started to come up with counterarguments just by being exposed to various opinions. I think this is one of the reasons for studying philosophy.

7. Change that begins from the end, and the strength of accumulation

Kurt Lewin's unfreeze, change, refreeze is a concept that often appears in MBA organizational theory as a way to restructure organizations. The idea of unfreezing, that "something must end for a beginning to occur," is particularly interesting, and I believe you cannot start something new without ending something first. I felt that it means you cannot move forward unless you unlearn and let go of something.

Regarding Max Weber's charisma, in his classification of the three ways to dominate an organization: 1) traditional authority, 2) charismatic authority, and 3) legal-rational authority, it was refreshing to see that charisma is not just popularity or an innate quality, but rather something that is intentionally and artificially constructed. I have recently felt that the accumulation of actions visible to those around you is what builds a person's charisma.

From Robert King Merton's Matthew effect, I was made to think that the seeds of the next success or activity lie precisely on top of what I have already accumulated. Rather than "standing on the shoulders of giants," in my case, living while carrying the IT, AI, and business experience I have built up is closer to the image of
standing on the shoulders of my past self.

Finally, Taleb's Antifragility was a particularly interesting concept among the key concepts this time. Unlike "robustness," which simply means enduring external pressure or shocks without breaking, antifragility refers to the property of actually improving performance when exposed to external pressure, stress, and volatility. It was a concept I didn't have before, and I read it with great interest as an organizational theory, learning that there is a way of being that turns change and adversity itself into strength, on a completely different axis from the idea of aiming not to fail or get hurt. I understand that the decisive difference from robustness is not just being tough or having many failures, but that the performance is boosted by those very blows and failures. I feel this is a way of thinking that also connects to
Hōsei Hōkigi's "Negative Capability" which I read previously.

Summary

Through "Philosophy as a Weapon," I realized that the thoughts of philosophers can be used not as knowledge in history, but as tools to re-examine the decision-making and human relationships right in front of us.
In situations like 1-on-1 feedback and team building, I want to create an environment where not only I but also those around me can proactively demonstrate their strengths, while keeping concepts like flow and the devil's advocate in mind.

Next time, I will introduce Chapter 3 (Society) and Chapter 4 (Thinking).
