This is a journal of philosophical thought, selected from the notes author Reza Saberi has kept over the past eleven years. Many existential and metaphysical questions have been examined, analyzed, and answered in this book. Examples include: What is reality? What is my relationship to the world? How do I know that which I know? How do I know that I know? Is there any meaning to human life? What is the purpose of life? What is the purpose of human existence? What is the purpose of the existence of this universe? How does the universe work? Did the universe have a creator? Insights and Intuitions is of special interest to students of philosophy, but everyone who cogitates upon the nature of existence can benefit from it. The book does not offer a system of philosophy or a systematic philosophy, but rather incites the reader's mind to explore the reality of existence from different angles.
