This book disentangles the foundations of coopetition (i.e., concurrent competition and cooperation) by exploring in-depth the intellectual legacy of Eastern and Western perspectives. In particular, it detects the foundations of coopetition in three Chinese streams of thought; Confucianism, Taoism, and Legalism, and in five Western schools of thought; David Hume, Adam Smith, Immanuel Kant, Georg Wilhelm Frederich Hegel and Søren Kierkegaard. In such a way, it unveils four logics used to tackle the essence of coopetition, respectively either/or, both/and, both/or, and either/and.
