One hoped with Sigmund Freud that psychiatry would replace religion. Religion has declined, psychiatry has advanced in numbers and cost -- but nothing has changed for the better. The crazies are still out there killing and maiming; the practitioners are still flush in fees without much success to show other than financial. The miserable stay miserable. The pill-pushers have some success, but in the end the pills do more harm than whatever real or imaginary disease they are supposed to cure or control.
Perhaps it is the human condition which is the problem. And a cure? Have we ever found one? Not in religion for sure. Not in politics for sure. Perhaps global warming will cure mankind finally by destroying him.
