Interesting. Circumstantial evidence to be sure, yet no worse than the circumstantial and theoretical science pass along in all three major theories.

No man of true thought would discount one theory for lack of irrefutable fact for another with the same deficiencies.

That is truly the sign of a person with a mind closed in order to sustain a fantasy.

I am cautious about anyone- - -physicians/psychologists included who allow themselves to be considered "experts" on human behavior. Benjamin Spock's observations on child-rearing left a lot to be desired. Whether or not he abandoned one theoretical construct for another is less disturbing than the fact that his celebrity was achieved for dispensing flawed behavioral advice IMHO.
