The Unikarg empire, controlled by officials on Exora-a whole management planet run by computers (exors)-has become an inert superstructure which, despite its high technology, is incapable of producing any new discoveries, ideas, art, even humor; the stimulants of change and difference, of vitality and growth, have been running down. The only glimmer of hope is a long-forgotten massive experiment launched eons ago by the genius Zeera who, having anticipated this decline, had set up the Plan for Experimental Planets (PEP). It involved seeding genetic diversity and disorder on planexes hoping that this would yield a new breed of minds and civilizations whose dynamism would rekindle the creative spirit on Unikarg. Erdoes investigates his hunch of a major trafficking in humans, technology and resources on Trisorbe/Earth. As he left secretly for Trisorbe with young intuits, the PEP assigns two agents to discover his plan: Shari and Vris, who break into Erdoes' complex. While Vris studies the exor Sphinx' new neural structure, Shari probes its logical tools and data. Trying to get to the essentials of the logic, Shari is in fact furthering the logic's sophistication, which triggers leaps in Sphinx who, adapting to its user, becomes more and more sharp. Shari gets drawn deeper and deeper into a battle of wits with Sphinx; the more she approaches her objective-the core of the new logic-, the greater the risk of triggering the exor's third alarm which would spell her own death. Thus, Shari is now the main node in Erdoes' master-plan: in trying to discover the exor's secrets, she has boosted its powers, shaping the growth of a formidable new intelligence. The Shari-Sphinx pair tackles the rules of randomness and statistics, and derives new Logical Forms-or LogForms-to deal with meaningful coincidences and synchronicities. They use Chaos Theory's Butterfly Attractor to elaborate a complex dual processing of data according to whether the phenomena fall into the classical random category or into the synchronicities and psi category. Finally, Shari invents Synchronicity LogForm and the Observed-Observer LogForm-able to process the influence of one's interpretation of events on one's own mind. The nonlinear logic is thus able to process the most complex mental processes-shifts in states of consciousness, psi phenomena and psychokinesis, retrocausality, or the bending of random events by a mind. But the corrupt elements of the PEP are not about to allow Erdoes upset the status quo; illegal trade with the Planexes is big business. While the PEP Director schemes for Erdoes' utter disgrace, the Deputy Director leaves for Trisorbe with dark designs for Erdoes' intuits. The fight is raging in several places on Trisorbe-will Shari and Vris be able to defeat them? Butterfly Logic-a sci-fi on Artificial Intelligence (AI)-offers a fresh look on diversity, creativity, chaos, artificial intelligence, and the human mind. Quick paced, provocative and humorous, this sci-fi deals primarily with the dangers of uniformization and a too tight control on people and society, as well as with a logic enabling computers to learn exponentially, while remaining the sure allies of sapiens and humans. It interweaves several issues facing Artificial Intelligence (AI) and the philosophy of mind: What are the true differences between human and artificial intelligence? Can computers reprogram themselves, thus demonstrating a form of free will?
