I consider myself to be a grounded, rational individual. I am not excessively emotional. I like facts, data and reason as opposed to hyperbole, rhetoric and bluster. That being said, I am aware that the world is an imperfect place. Opinions are often not based upon empirical fact but personal perspective. Hence many people experience reality differently to me. They are driven by their feelings and other factors. However, despite these differences in philosophy, for most of my life the world has remained functional and over time slowly improved in subtle ways. Deference to expertise, a sense of community and basic pragmatism meant that people broadly pulled in the same direction. Of course there has always been dissent but it has been within a stable system. However, of late I feel that this era is now finally over. Things are no longer stable. We live in an uncertain world.
