Philosophy is the science that studies beings in their ultimate causes, reasons, and principles through the aid of human reason alone. It is concerned with understanding the fundamental reasons and principles behind all things that exist, through questioning. Philosophy attempts to understand things in a logical and critical manner. It helps develop skills like critical thinking, problem solving, and understanding different perspectives. Philosophy is important for personal development as it encourages examining one's life, beliefs, and principles. It also helps people make more reasonable moral decisions and potentially improve society.
