Philosophy is the study of big questions about life, knowledge, truth and reality. Philosophers ask questions like: What is right and wrong?, How do we know something is true?, and What makes a good life? Instead of just accepting ideas, philosophy encourages people to think carefully, ask questions, and give reasons for their opinions. In RMPS, philosophy helps us explore different viewpoints and develop our own ideas through discussion and debate. 

Perception is about how we experience and understand the world through our senses, such as sight, hearing, touch, taste and smell. Philosophers study perception because it raises important questions about knowledge and reality. For example, can we always trust what our senses tell us? Sometimes our senses can be mistaken, such as when we see optical illusions or misunderstand what we hear. Because of this, philosophers ask whether our senses give us a completely accurate picture of the world, or whether they sometimes mislead us. Studying perception helps us think more carefully about how we know things and how we understand reality. 

In philosophy, evil is the idea that some actions, choices, or events cause serious harm or suffering. Philosophers study evil by asking questions such as: Why do people do bad things? and Why does suffering exist in the world? Some philosophers focus on moral evil, which is harm caused by human choices, such as violence or cruelty. Others look at natural evil, which is suffering caused by natural events like earthquakes, diseases, or floods. Studying evil helps us think about responsibility, human behaviour, and whether it is possible to explain why suffering happens.
