Collectivism holds that the individual has no rights, that his life and work belong to the group (to "society," to the tribe, the state, the nation) and that the group may sacrifice him at its own whim to its own interests. The only way to implement a doctrine of that kind is by means of brute force - and statism has always been the poltical corollary of collectivism.
Ayn RandLook around you and look at history. You will see the achievements of manโs mind. You will see manโs unlimited potentiality for greatness, and the faculty that makes it possible. You will see that man is not a helpless monster by nature, but he becomes one when he discards that faculty: his mind. And if you ask me, what is greatness? I will answer, it is the capacity to live by the three fundamental values of John Galt: reason, purpose, self-esteem.
