I think what Dr. Grump is saying is that spiritual needs are not natural or instictive, but learned.
If that's what he's saying, I disagree. I believe that we all have an instinctual longing for something greater than ourselves.
I think all mankind are born with a need to know why, and for all time that need has been filled with different beliefs, superstitions and odd practices that have satisfied that need in man.
Its a passion among some, something to grab and hold onto, answers for the unknowns in life that satisfy a need for others. Some accept that there are no answers, by or from man at least.
Joseph Campbell had a great serious on PBS years ago called the power of myth.
It was amazing how many beliefs, stories and explanations for life were similar throughout time, and seem to transcend all cultures.
Mans way of explaining the unknown, I guess.
I dont think spiritual is taught, I think religion is taught.
The "why" questions are facinating as are the "who" questions. The anwers to them must be pretty important because people sure argue about them alot.
So religion is a choice you make as a factor in fulfilling you spiritual needs?
Man was created with needs, period.
We are all born with spiritual needs, how we fulfill them depends upon what we learn during the course of our lives.
I'm not really sure but the pursuit of these answers makes life much richer in my opinion.
