Humans are biologically wired to look for patterns and causes. This drive is at the heart of our most important disciplines: causes
: Because of , since , on account of , due to , the reason for . : A necessary cause must be present for

The concept of "causes" is the engine of our reality, driving everything from the microscopic shift of a tectonic plate to the grand sweep of human history. Understanding what makes things happen allows us to predict the future and change the present. The Invisible Threads of Causality
