Book description This book treats the challenge of general survival, which emerged in the middle of the 20th century, from the standpoint of applied philosophy. For the first time in human history there is a clearly recognisable danger, already obvious through the possibility of nuclear warfare, which can threaten the existence of all communities together. Accordingly, it takes up the theme developed over the past century of linking reason and emotions together, instead of assuming they are antagonists. Despite the complexity of our notion of reason (rationality in modern usage), it might be a protection if supported by a range of emotions from fear to empathy. Owing to the problems of traditional just war theory, both in terms of the ambiguity of the concept of innocence underpinning between combatants and non-combatants and the general blurring of boundaries between civilian and military, practices of nonviolence may offer better prospects. The model of sport and games could be useful if that could be ramped up to a scale relevant for political affairs.
