The present Handbook pursues the ethical intention of convincing readers who are willing to procreate that it is better not to act in such a way that new human beings begin to exist. It aims to encourage readers who are critical of procreation in their antinatalist stance. To this end, the handbook offers a variety of arguments, neologisms and opinions on natality from millennia. The antinatalism we advocate is universal in that it takes into account all beings capable of suffering.
