I am reminded of the story of the man who jumped off a 20-story building. I am also left very thoughtful about social versus political movements. Take holistic health for example. It started small and to the mainstream seemed strange and marginal. As positive results began to happen, there was more interest.
Journals appear to promote professional debate as well as publicize small scale successes.
At some point, merchandisers entered the fray, peddling products to doctors and to the general public. Eventually, pressure was put on the system to change the rules so that holistic treatment could be insured, administered in those standard allopathic palaces called hospitals, etc. Sustainable agriculture is going through a similar process. I believe that the simplicity branch of our family is cooking along famously and is starting to hit the limits of what slow diffusion can do. Systemic changes may be coming soon.
