What I call stupidity is not only lack of knowledge, although much of humanity could be elevated from poverty, dogma, illusions and war through traditional education. A thriving education system is the foundation for progress. But stupidity is not merely ignorance; it can also be a way of acting. If you act contrary to your own goals in life – you’re stupid.
