Yes, there are, but they are defective. Most of the most consistent writers and answerers of questions avoid 'why' questions altogether unless they want to enter into the discipline of psychology for a moment and instead use 'how' questions that call for some kind of explanation, as in descriptive sciences or sciences of law, or even historical science.
Good points thanks.
And, I think illustrative of the limits of science. It measures, describes and creates models of the physical universe.
Very interesting and useful knowledge, but still a level below the questions posed by the article.
thanks for your reply.
