So little in so many words? It's the complete opposite. When Peterson use words like: Order, Chaos, God, Meaning, Sacrifice, Self etc, they have multiple meanings - yet when you add the context, the meaning is exact and says a lot in just a few words.
For instance, the idea of the highest values of the intrinsic* principles that humans have can be summarized by the figure of Christ.
*Neurology, Darwinism and the very fashion that our eyes look at things imply that humans naturally assign more or less value to everything
Order and Chaos can mean the left and right hemispheres of the brain, which makes connections between concepts using logic/unlikely connections between concepts respectively; at the same time Order can mean when our expectations are met and what we know; Chaos is the opposite but it's also the potential for growth.
With only one word, Peterson can imply a complete philosophy with several different ideas and values.
"Humans are protected by something invisible from something that they can't comprehend", the first something is culture - with every meaning relevant to the context, the latter something is Chaos, with every meaning relevant to the context
This phrase has so much meaning and implications that one could read a complete book about it.
