Los Horcones is based on the science of behavior and radical behaviorism. Skinners' novel was a fictional account based on his subjective view about how behavioral principles could be applied to a community. We learn to be as we are. We are not passive in the face of our environment. We are not machines that respond to stimuli, we interact with our environment and change it.
Radical behaviorism is a humanistic philosophy.
It seeks the best for all people. See Radical Behaviorism 3. Walden Two is just Skinner's personal version of a fictional society that has applied the science of behavior to its design. It is important to remember that he wrote his novel back in 1945. From that date up to now, the science of behavior has advanced greatly.
