From the article:
Science is a rigorous way of making fewer mistakes. Its not very useful to people who already know everything. Science is for stupid people who know how much they dont know.
I recall a study done on the attitudes of people with various levels of intelligence.
What struck me was this:
Stupid people were too stupid to realize that they were stupid. They thought they were smart.
Smart people were smart enough to know how limited their knowledge and intelligence were. They were humbled by how little they knew.
That truism shines throughout this marvelous essay.
