From diamonds that can be measured and graded to ideas that have shaped civilizations, Shailendra Srivastava explores matter, mind, technology, belief and the unanswered questions of human existence.
Featured Book
THE BIRTH OF GOD
How the Human Mind Created the Idea of God
This book does not begin by asking whether God exists. It asks a different question: How did the idea of God emerge in the human mind?
An inquiry into the historical and cognitive emergence of the God-concept — through evolution, mortality awareness, dreams, imagination, agency detection, language, culture, religion, civilization, consciousness, science and philosophy.
