This is fascinating. I just finished A Brief History of Everything. In it, the author (Ken Wilbur) posits that one of our failings as humans is that we tend to focus on a certain aspect of development at the expense of others--so not unlike Kierkegaard's assessment .

Wilbur says everything can be reduced to four quadrants: internal individual (The "I" quadrant, which is our own personal experience and how we process it); internal group (The "We" quadrant, which is our shared beliefs, customs, rituals, ethics, etc., ); the external individual (The "it" quadrant, which is our physicality and senses that can be scientifically accessed and measured) and finally, the external group (The "its" quadrant, which is the world of matter and industry that can be seen/touched, etc.)

When any of the four quadrants are ignored (for example, when people ignore spirituality because they can't measure it scientifically) we get off balance.

So, Kierkegaard recognized that too much emphasis on external "we" stuff means that too often the internal "I" stuff gets lost.

I call this outsourcing of spirituality--letting organized religion take the place of personal spirtual development.

Sorry for the novel! I'm enjoying your writing! I just joined the Medium Master Class myself.
