A Buddhist-Christian Logic of the Heart explores the philosophies of Being and Nothingness as expounded in the Buddhist and Christian point of view with particular emphasis on the socioethical implication that all human beings, despite vast differences in history, language, and culture, share the cognitional, intentional makeup as emphasized by Nishida and Lonergan. The author claims that all humans are endowed with this cognitional inbuilt bridge, which can be compared to a spiritual genome or a world bridge.
