I gave the opening lecture at Freedom Week at Sidney Sussex College in Cambridge last week. My theme was "Flux versus Stasis," and I contrasted the views of Parmenides and Heraclitus, two of the Presocratic philosophers. Parmenides took the view that nothing changes in reality; only our senses convey the appearance of change. Heraclitus, by contrast, thought that everything changes all the time, and that "we step and do not step into the same river," for new waters flow ever about us.
I divided the world between those who seek permanence (the stasis of Parmenides) and those who embrace change (the flux of Heraclitus). Those who prefer stasis resist change and innovation, and try to keep society following traditional practices, using social pressures and, if necessary, the force of law to sustain conventional norms. They include people who resist technological change and the changes it brings to employment, as well as those who urge subsidies and tariffs to sustain domestic markets against foreign competitors.
Those who accept that change happens and try to adapt to its flux follow Heraclitus. Their societies allow experiment and innovation, even knowing that some will be upset by the disturbance they bring to traditional ways. They allow markets to pulse and flow, reacting to inputs, and adapting to and coping with those changes.
Stasis societies value order and tend to entrust government to maintain their status quo. Flux societies value new ideas and look for progress toward their citizens' goals. It is the flux societies, the ones ready to embrace change and develop its positive aspects, which are most friendly to liberty and the right of people to pursue self-referring goals unimpeded by arbitrary restrictions imposed by others.
