Our needs are no longer merely natural. To hunger we add the idea of how we eat. To feeling cold we add the idea of what we wear. The spiritual side wins out.

Why is this a liberation?

Because the harsh necessity of nature steps back. Now a person rather follows an opinion that he shares with others. This is a necessity too, it is true. But it is a self-made one.

The state of nature:

Some believe: In the state of nature, man was free. He had only simple needs. Nature gave him what he needed. This is a mistake. A life that sinks wholly into nature is raw and unfree. Freedom only arises when spirit sets itself apart from nature and acts back on it.

Summary: In the needs of society, the spiritual side wins out. In this lies a liberation from mere nature. The so-called free state of nature is in truth raw and unfree.
