Dear Robert and Friends,

        Just a brief comment. I am familiar with the mentioned aspect of
Prigogine's work. But, it seems that the author of this paper should try
living as an "untouchable" within the Indian caste system! It reminds me
of his thoughts on eusocial individuals. "Specialization builds in
weakness" from Ghost in a Shell
