Early in my career, I was disappointed that psychoanalysis was not becoming more empirical, was not becoming more scientific. It was primarily concerned with individual patients. It wasn't trying to collect data from large groups of people who have been analyzed.
Visit a typical science classroom and you will discover far more than empirical facts being taught. The dominant worldview among scientific intellectuals is evolutionary naturalism, which holds that humans are essentially biochemical machines.
During my sojourn in ironclad atheism, the primary arsenal leveled against Christianity had been its failure on empirical grounds. Surely, enlightened reason offered a more coherent cosmos. Surely, Occam's razor cut the faithful free from blind faith. There is no proof of God; therefore, it is unreasonable to believe in God.
The wonderful thing about theater as an art form is it's a purely empirical art form. It's all about what works. And every show, every production, is created anew right from the moment you go into the rehearsal hall.
