This book addresses nothingness as not only the intangible presence of an emotional, cultural, social, or even political void that is felt on an existential level, but has some solid foundations in reality. The death of a loved one, the social isolation of an individual, or the culture shock one may experience in another country are examples of situations in which an external sense of absence mirrors an internal psychological and philosophical sense of nothingness. Not much has been explicitly written on nothingness in the history of psychology. On the other hand, nothingness seems to be implicitly embedded in many scholars' work. This duality of explicitly and implicitly expressed ideas about nothingness reveals how psychology finds inspiration in philosophy, and vice versa. The book aims to illustrate how the concept of the presence of absence-nothingness-fills a void in contemporary psychological theorizing.
