On the Fourfold Root of the Principle of Sufficient Reason, and On the Will in Nature: Two Essays (revised edition)

"On the Fourfold Root of the Principle of Sufficient Reason, and On the Will in Nature: Two Essays (revised edition)" by Arthur Schopenhauer is a philosophical examination from the 1800s into why everything happens for a reason. The book puts forward the Principle of Sufficient Reason, which says that there's always a cause behind every event, and examines how this shows up in different areas of understanding. Schopenhauer values a step-by-step way to dealing with philosophy and builds the basis for his larger philosophical ideas. The initial parts of the book show why considering the Principle of Sufficient Reason is important as it relates to the basics of learning and science. Referencing philosophers like Plato and Kant, Schopenhauer emphasizes how important it is to be super clear when explaining principles of reasoning. He wants to separate the different uses of the principle and argues against previous interpretations, pushing for a more complex understanding of the principle. This gives way to a more thorough look into how the principle affects many different kinds of questions, pointing out how important it is to really get at philosophical truths.
