A riddle or a joke? I regret having made light of both myself and the reader. However, the concept of complexity has been explored with such intensity and pedantry, has been analyzed from so many points of view – the mathematical, linguistic, physical, chemical, political, psychological, sociological, physiological, algorithmic, logical, religious, and metaphysical – that nothing, not even the title of this piece, can escape it. Indeed the situation has reached the point where we grow misty-eyed over the very thought of the discrete charms of yesterday's simplicity. Sometimes we dream that complexity itself, after having given us so much, muses – now that its task is fulfilled – of flying up miraculously into the sky, like the Virgin Mother (the Assumption); or ourselves wish to experience – for those spirits who prefer to keep their feet on the ground(!) – the “dissolution” with which entropy begins. Isn't it true that certain words, marked by the spirit of their age, are themselves in fact carried away by the spirit of the age?
