Many educated people today dismiss free will as an illusion and instead view themselves and other people as determined by their environment and their genetics. Objectivism offers a very different view. It holds that the key to understanding yourself as a human being is that your mind functions by choice. This gives you a fundamental, delimited control over your own life and actions, which you can choose to exert or not. Further, a proper understanding of free will shapes a proper understanding of good and evil and of the nature and personal importance of justice.
