We need liberty to think, to plan, to create, and to fulfill our potential. Liberty is as much a requirement of our psychological nature, as food and air are requirements of our biological nature. Without liberty, economics stagnate, culture deteriorates, science declines, and we lose our humanity. Liberty is so powerful and important that even brutal dictatorships invoke it.
Tyranny always fails because it is coercive, and coercion is incompatible with human nature.
Liberty is the ability to control your own mind, body and life, without interference by others. Liberty, is one of the primary social conditions necessary for a moral and practical way of life. Liberty is also the recognition by members of society that to be happy and prosper, people must not coerce others. Force should be used only in self-defense. Liberty includes the right to acquire, control, use and dispose of property.
