It seems in some of the discussions, that some people are less aware of the degree to which we are shackled by our biological heritage than I am. [Or they may simply want to believe this.]
I realized in reading an pharma-industry newsletter (Emerging Pharmaceuticals) tonight, that one reason for this may simply be that I've been somewhat immersed in the Biotech/Pharma industry for many years and have information sources that reach the public later or in a much distilled or distorted form.
So, I thought I would throw out a few tidbits from the Sept. 1999 issue of the newsletter:
So, we have "cravings", "wakefullness", "appetite" and "body rhythms" under the control of these little molecules. I believe that I may have mentioned in a previous post that leptin appears to be the hormone for triggering sexual maturation.
Since we have only scratched the tip of the iceberg, I think the people who want to believe "I *am* my own master", have their work cut out for them in defending, what I predict will be an ever shrinking set of characteristics, behaviors, desires, motivations, etc. of which they are the master. Yes, we can modify ourselves, but our degrees of freedom are *limited*, until we have the technologies to change the hardware.
