Objectivism is a philosophy introduced by Ayn Rand that is based on a logical process using metaphysics, epistemology, and ethics. It holds that objective reality exists independent of consciousness, knowledge is gained through reason using concepts derived from reality, and ethics is based on rational self-interest and the pursuit of one's own happiness. In politics, Objectivism supports capitalism and limited government as the most moral social system that protects individual rights while avoiding the use of force. The philosophy aims to provide a framework for understanding existence and guiding one's choices and actions in life.
