What is the difference between philosophy and psychology?

Philosophy and psychology both explore the human mind and behavior, but they differ in approach and method. Philosophy examines fundamental questions about the nature of mind, consciousness, free will, knowledge, and ethics through reasoning, logic, and argumentation. It asks questions like "What is the nature of consciousness?" or "Do humans have free will?" without necessarily relying on empirical testing. Psychology, by contrast, is an empirical science that studies human behavior and mental processes through observation, experiments, and data collection. It seeks to understand, predict, and explain how people think, feel, and behave. While philosophy laid the groundwork for psychological inquiry, psychology broke away in the late 19th century to become its own scientific discipline grounded in measurable evidence.
