Something is really wrong with our reality. It appears that our minds are being manipulated. Synchronicities and the collective unconscious are clues about the mind manipulation mechanism. This mechanism is the God effect, according to the author. The God effect implies that there is an intelligent entity controlling our minds. Who is this intelligent entity manipulating our minds? A God must be responsible for the God effect. How exactly is this God manipulating our minds in this reality that is based on the principles of materialism that we know so well through our sciences? We are unable to account for the God effect within the paradigm of materialism. Are we in a reality based on idealism, where consciousness is fundamental and an intelligent God exists in this context? Or are we living inside a computer simulation? What is the nature of our minds? In order to account for God, we have to question our understanding of our reality, and we have to ask if we are truly in control of our minds, thoughts, and actions. This is a gist of the God, mind, and reality problem that the author tries to discuss in this book. In his first book, the author wondered if a simulation accounts for the God effect. In this book, he wonders if idealism, with consciousness-first principles and an intelligent God, solves the problem.
