Dear Alex,

The problem with my analogy between medicine and an hypothetical
political science is that there exists some fundamental knowledge
about the structure and function of the human body - taught in 
anatomy, physiology, biochemistry, bacteriology and pathology courses
in medical school. If any corresponding fundamental knowledge about
sociology and social psychology exists, it's escaped my notice, and
I surmise that until such fundamental knowledge is discovered (or
invented) politicians cannot become physicians of society and will
remain - politicians.

Love Jochen
