This book is a collection of essays on the philosophy of life’s meaning in contemporary society. Topics range from antinatalism, meaning of life, the trolley problem, to painless civilization. I am now writing a comprehensive philosophy book on those topics, but it will take several years to complete; hence, I decided to make a handy book to provide readers with an outline of the philosophical approaches to the meaning of life that I have in mind. -/- Chapter One discusses the (...) definition, history, and category of antinatalism. Antinatalism is the thought that all human beings or all sentient beings should not be born. Although I am not an antinatalist, I believe that antinatalism poses an important question about procreation and the meaning of our lives. This is why I presented an overview of antinatalistic thoughts in the past and the present and also performed an analytical examination of their arguments. -/- In Chapter Two, I take up Philosopher Thaddeus Metz’s argument on meaning in life, especially his fundamentality theory, and claim that “the heart of meaning in life,” which is the concept I propose in this chapter, cannot be compared with anything whatsoever. -/- Chapter Three deals with the concept of “birth affirmation,” which means that I can say “yes” to my having been born. I believe that birth affirmation is one of the most promising ideas that can contribute to contemporary philosophical discussions on meaning in life, and I call this approach “an affirmation-based approach to meaning in life.” The concept of birth affirmation has two dimensions: the psychological dimension and the philosophical dimension. I would like to show in this chapter that it is difficult to clarify what it actually means to say “yes” to my having been born. -/- Chapter Four discusses the relationship between the dropping of the atomic bombs and the trolley problem. I argue that the dropping of atomic bombs was a typical example of the events that contained the logic of the trolley problem in both their decision-making processes and justifications. I further argue that the trolley problem has its own unique problems, which I call “the problem of the trolley problem.” This problem has been overlooked in academic discussions of the trolley problem. I also refer to a religious aspect of this problem. -/- In Chapter Five, I talk about the “philosophy of life” as an academic discipline. We have the philosophy of language, the philosophy of religion, and the philosophy of history, but why don’t we have the philosophy of life in the field of philosophy? Of course, we have Lebensphilosophie, but it does not cover philosophical discourses in ancient worlds, nor current analytical approaches to the concepts of life and death. A new research field is required to advance contemporary philosophy. -/- In Chapter Six, I illustrate an outline of my “painless civilization” theory, a criticism of contemporary civilization that deprives us of a joy of life in exchange for eliminating pain and suffering. I also discuss the concept of “fundamental sense of security,” which is considered indispensable for us to be able to live a life without regret. (shrink)

This paper asks three inter-related questions, proceeding chronologically through a divorcee’s experience: is it responsible and rational to make an unconditional marital vow in the first place? does divorce break that unconditional marital vow? And the main question: can the divorcee make a second unconditional marital vow in all moral seriousness? To the last question I answer yes. I argue that the divorce process is so disorienting – to use Amy Harbin’s term – as to transform the divorcee and therefore (...) partly release her from the original vow. Arguing this will require a specific understanding of personal identity and change. (shrink)

How can we rationally make peace with our past moral failings, while committing to avoid similar mistakes in the future? Is it because we cannot do anything about the past, while the future is still open? Or is it that regret for our past mistakes is psychologically harmful, and we need to forgive ourselves in order to be able to move on? Or is it because moral mistakes enable our moral growth? I argue that these and other answers do not (...) properly resolve the problem of temporal asymmetry in our attitudes toward moral imperfection, and I defend an alternative response, centered on our personal attachments and our biographical identity.
