grasping how Newton and Darwin differ.  The Newton pattern is science’s holy grail: universal laws, fixed interactions described by tightly causal equations. The Darwin pattern is fundamentally different: universal processes whose logic, applied locally, creates a looser causality, including parts with behaviors that aren’t fixed, often involving choice and change. Hence detailed outcomes aren’t as mathematically describable or predictable. - http://bigthink.com/errors-we-live-by/modeling-the-muddling-masses
