The
problem with categorizing everyone is that it leads to pigeon hole
thinking. B.F Skinner was the father of Behavioral Psychology. He
used an apparatus called a Skinner Box to train animals. Rather than
try to stuff you in a Skinner Box, I'll assert that as we mature we
go through more than one stage of development. I will not pretend to
offer an exhaustive list, but rather list as many as I can account
for, and agree that people at large try them in the order that they
think of them, not in some programmatic tier system.
Lastly,
there is no final state or “box” of maturity, so that anyone can
just jump to the end, and be instantly mature. This book is to help
us all think more clearly about the problems we face at our various
levels of development.
