The human person is called a rational being because humans have the ability to think, reason, and make logical decisions. Unlike animals that act mostly on instinct, people can analyze situations, understand cause and effect, and solve problems using their intellect. This rationality allows humans to learn, plan for the future, create laws, and develop systems of knowledge such as science, philosophy, and art.Being rational also means humans can reflect on their actions and make moral choices. We can think about what is right or wrong, weigh different options, and choose the best course of action based on reason rather than just emotion. This ability to reason is what sets humans apart from other living beings and is a key part of our identity as persons.
