Objectivism
Rand's name for her philosophy as a whole.
A complete philosophical system: reality exists independently of anyone's mind (metaphysics), reason is the only means of knowledge (epistemology), each person's own life and happiness is the proper aim of their actions (ethics), and laissez-faire capitalism is the social system that protects individual rights (politics). Rand also set out a theory of art.
