The following essays focus on consciousness, neuroscience, evolutionary biology, artificial intelligence, computer science, virtual and augmented reality, and more. Each chapter stands on its own and doesn't require prior knowledge about the subject, though having a background in philosophical and scientific thinking is a plus. These essays, with a few exceptions, were originally published in Europe on the Integral World website during the past decade. I have added a postscript to several essays to bring them up to date and add the latest insights culled from the latest research in all things related to A.I. and V.R.
