Abstract
When Immanuel Kant is referred to in the context of business ethics, the categorical
imperative is treated mainly. But he also argued for the importance of cosmopolitanism
in an essay entitled “Toward Perpetual Peace.” In this text, I will show that the
cosmopolitanism is associated with business ethics. First, I examine a concept called the
cosmopolitanism in terms of the thought history. Second, the Kantian cosmopolitanism
is introduced and the importance of the concept “publicity” is considered. Then, I take
notice of the space where the reason is used officially. As a result, I release the concept
“publicity” from the political philosophy and apply it to the business ethics.
