Firstly, Celestina, thank you for the invitation to your closet.
Here is an article that deals with a taboo: the idea that the world has gone mad. It's written by my favourite voice in the wilderness, a man called Michael Leunig who is a master of the whimsical and poetic varieties of philosophy.
Such a primal and outrageous question [is the world mad?] is probably regarded as too general in a time of specialised empirical investigation; best left to new-age psycho-babble practitioners and to the speculations of poets and prophets - or the tattered remains of them - those traditional voices in the wilderness who cry "This way lies madness". The ordinary people, who are us, mention it in the street with gloomy or bemused resignation and it blows away in the wind.
