What is the meaning of life? There are so many philosophies, religious systems—who should we believe, how to understand what matters most? Does God exist, and what is the Church for? This is the level of questions that makes a person a person. Not everyone reaches it, but if it does happen, then they face questions about themselves, about the world as a whole, about being—and, of course, about God. In his book “The Last Man,” Archpriest Andrei Tkachev tries to answer all these questions.
