This book is a journey through the cosmos in search of consciousness. We think consciously of what we think, feel and decide with our brain, but is our consciousness really unique? This theme takes us along an interesting journey through cosmology, relativity, particle physics, quantum physics, chaos theory, information theory, brain science, evolution, intelligent design, the origin and history of religion, the theory of the self, free will, and much more. The main theme of this book is the pantheism of Spinoza, our great compatriot. The scientific results of our time fully vindicate him, 300 years after his death. The book is a gesture of the natural sciences to the metaphysical without becoming too woolly.
