Function Levels

I am making the argument that Carl Jung's four psychological functions (Intuition, Sensing, Feeling, and Thinking) originate as developmental levels.


  • Intuition has similarities to how people experience the world in infancy;

  • Sensing has similarities to how people experience the world in childhood;

  • Feeling has similarities to how people experience the world in adolescence; and

  • Thinking has similarities to how people experience the world in late adolescence and adulthood.


I don't have any formal education or training in psychology. I have an amateur interest in Jungian psychology, and the blog is written from a layman's perspective.

This blog is an amateur project and is still a work in progress. I have completed the chapter on Intuition, and I'm two-thirds of the way through the chapter on Sensing. I will be posting more essays to the Sensing chapter in February - March 2024.
