Constructivism is perhaps the most important idea that will shape the future of humanity. The ills of society are a consequence of the willful ignorance of constructivism.

There are two important definitions of constructivism, one comes from mathematics and the other from psychology. The mathematical definition leads rejects the law of excluded middle. It's relevant in understanding causation.

The psychological definition: "Humans actively construct their own knowledge, and that reality is determined by our experiences as a learner."

The models of causality that our brains invent to navigate the world is a consequence of our progressive development in the world we live in. Robert Kegan calls his theory constructive developmental theory to emphasize two important aspects of cognitive growth.

Cognitive growth is constructive as explained above. It is also developmental in the sense that our mental models of the world make abrupt changes as we grow in maturity. The symmetries in our models break and lead to new symmetries.
