    «Lightning Chess - The information age
    demands a way of thinking that employs
    the full bandwidth of our senses
    by Koert van Mensvoort»



    Our traditional way of thinking is aimed at decision-making on the grounds of scarce and incomplete data. Now every day we are swamped with data. This asks for a different way of thinking. Our text-led culture is obsolete. We are flooded with visual information from television and the Internet. Important issues are increasingly decided upon by our response to imagery.

    In order to understand visual thinking we need to look at man's original natural environment. This is the origin of our modern reality and it is where the way in which we experience information is rooted [1, 2]. Our senses have developed and are finetuned to our natural surroundings. In our original natural environment there was no text and media did not exist. The natural habitat had a certain directness. Every symbol was an object. We have improved on reality by draping a layer of language and technology over our original environment. We have structured our societywith linguistic institutions like government, science and industry.

    But if we listen to Mozart today, we do so by using our hearing that was originally developed to alert us to danger and opportunities in the natural environment.

  • A crucial zone of combat straggles around the line L.
  • A great number of pieces of both camps occupy L.
