Morioka explores the definition and history of the term antinatalism in religion, popular media and literature. He then categorizes different types of antinatalism and lists common objections to their respective positions.

The concept of antinatalism is now becoming popular on the Internet. Many online newspaper articles deal with this topic, and numerous academic papers on antinatalism have been published over the past ten years in the fields of philosophy and ethics. The word “antinatalism” was first used in the current meaning in 2006, when the two books that justify the universal negation of procreation were published: one by David Benatar and the other by Théophile de Giraud. However, we can find various prototypes of antinatalistic thoughts in ancient Greece, ancient India, and modern Europe. You might recall the name Schopenhauer. In this paper, I briefly summarize the history of antinatalistic thoughts and propose a set of categories on antinatalism and related thoughts.
