Have you ever wonder, how this universe exists? How did the universe start from nothing?This work explores the question of why there is something instead of nothing. Several responses to this question are possible, but only some of them address the question seriously, respecting its emotional aspects as well as its cognitive dimension. It can be argued that the existence of the world has no explanation at all, or that there is a necessary being whose existence is self-explanatory, or that the world exists because it has value.Incorporating aspects of both the "analytical" and "continental" traditions, this book also responds to several historical philosophers concerned with these questions, including Plato, Leibniz, Kant, and Nietzsche.
