This book proposes a mathematical model of the psychological process which is integrated, holistic and systematic. Psycho-behavioural phenomena in this model do not remain disconnected and isolated, but rather exist within and in relation to the psychological process as a whole. The book proceeds logico-mathematically from premise to conclusion in a journey through the realm of psyche, making use of the mathematics of networks to represent and analyse the structure, function and evolution of the mind. Explaining and predicting a huge range of psycho-behavioural phenomena within the rubric of one model, this book has major implications for our understanding of mind, behaviour and self.
