This work is to honour Professor Peter M. Allen, a seminal figure in the 
    foundation and development of Complexity Science in human systems. 
    From before the time of his joining Nobel Prize winner Ilya Progogine’s 
    pioneering group at the Université libre de Bruxelles in 1967, Peter had 
    started publishing on what was then known as Prigogine Theory in Physics. 
    But it was only after this that his own pioneering work in Complexity 
    Science showed the importance of its applications in evolutionary and 
    human sciences. Since then he has been an influential and guiding figure in 
    this field. 
                
  
    The works collected are by admiring colleagues, friends and collaborators, 
    all leaders in their fields, influenced by his seminal ides, and gathered from 
    across a gamut of fields in human systems. This makes this a valuable and 
    unique work, a veritable reader in the influence Complex Systems theory 
    has on a wide and diverse range of fields; from archaeology, city design, 
    international banking, economics, policy studies and more.
