Taking steroids is only natural...

...according to Alva Noe in this Salon article. One of the central points undergirding the view Noe expresses is as follows:

Human beings are and always have been a technological animal. Ours is a history of shared technological innovation. Sharpened stones and cave paintings show up 80,000 years ago in the archaeological record. We are natural by design; we are designed by nature and culture. Once this basic fact about ourselves is clearly in focus, we are forced to acknowledge that using of steroids or other performance-enhancing drugs does not cross a bright line when it comes to personal responsibility. The athlete's reliance on steroids is no different in principle from a reliance on training techniques, newly designed footwear, sunglasses, mitts, nutrition or the computer-graphic analysis of plays. We are what we do and are never entirely self-sufficient in determining the scope of what we can do.

Noe also makes the argument at the end of the article that steroids are not sufficient for the skill required to hit a homerun in MLB, or have the kind of career that high-profile players accused of doping have had. Their talent is not dependent on the performance-enhancing substances.

I am a purist, I suppose, and think the bans on steroids and other similar substances are justified. I think that steroids are different in principle from sunglasses, mitts, and good nutrition.
