Many things in life are a product of dualisms like chaos and order, yin and yang, hot and cold, change and preservation. Unlike with good vs. evil, these are not simple opposites, but principles that need to be integrated. The right balance is not a static one for all time, but depends upon the needs of the time. I discuss this principle using immigration as a case study.  Immigration is not a matter of simply good or bad, but finding the right balance of dynamism and rootedness for the times.
