De La Cruz Introduction Preliminary Questions The book deals with devoted to three key questions concerning the relationship between complexity and natural language. Briefly, such questions are: (a) What kind of complexity for natural language? (b) Which theory of language in the perspective of complexity? (c) Whatsortsofmethodsandmodelsintheanalysisoftheobservedphenomena? All the essays in this volume show the reference to complexity as a constant element. However, the use of the singular may not be entirely appropriate. Let us see the reason why. What Does “Complexity” Mean? In the period between the end of the 1960s and the beginning of the new century, the word “complexity” was used to mean a variety of research programs aimed at different purposes, domains of investigation, and explanatory strategies; such as qualitative theory of dynamical systems, fractal geometry, physics of emergent processes, andcellular automata, to name a few. Aslightly deeper analysis on this fleeting sketch would also show that, in each of the above-mentioned fields, the internaldistinctionsoperatingwithinthekey-conceptsareresponsableforsuchbig and significant differences. The concept of emergence offers, in this sense, an exemplary case: it was introduced to manage novelty and unpredictability, which are peculiar of the so-called «systemic properties», but it was later articulated in severalotherdirections.Inparticular,wehavetomentioncomputationalemergence to indicate those types of unpredictability produced by an imperfect knowledge of the initial conditions of a given system—but precisely for this reason «tame- able», i.e. compatible with the «possibility to compute step by step»—by a given ix x Introduction model—the dynamics of the system. Instead, there has been talk of observational (or intrinsic) emergence to indicate those types of unpredictability that—far from being«tameable»inthespecifiedsense—involvea«deviation»betweentheactual behaviorofthesystemandtheonedescribedbytheadoptedmodel.Notonlythat: thetwoformsofemergences(forwhich,seeBaasandEmmeche1997;Licata2005, 2008) admit a large variety of intermediate cases. Among other things, a certain ambiguity in the terminology has increased the misunderstandings that already proliferated around the concept. Thus some authors, such as Lichtenstein (2014), haveused«computationalemergence»todenotethepatternsofinteractionthatare examinedinthecontextofArtificialLife,whileothers,asCariani(1992),usedthe expression «emergence-relative-to-a-model», instead of «observational emer- gence». In other words, this particular case (and many others, which we do not discusshere)clearlyshowsthat“complexity”referstoanetworkofplurivocaland stratifiedconcepts(such astheoneofemergence).That’swhysomecanthinkthat theuseofthesingular“complexity”isnotonlyinappropriate,butalsoincautiousin epistemological terms. Howtojustifyourchoicetoputthesingularnameinthetitle?Webelievethatit is possible to respond by advancing two reasons: the former belongs to the semisecular debate around the repertoire of concepts that has been made available bytheabove-mentioneddisciplinesandthelatter,oncontrary,belongstothedebate thatthisbookwouldlike,toacertainextent,toinaugurate.Letusstartfromthefirst one. Varieties of Complexity Accordingtothescholarsindynamicalsystems,fractals,cellularautomata,etc.,the word “complexity” represents a convenient umbrella term. The choice of the sin- gular is firstly justified primarily by a practical reason: the ability to evoke syn- thetically a plurality of different research programs and well individuated on the theoretical level. But there is more: this choice not only is the outcome of a conventionalagreementamongthemembersofoneormorescientificcommunities, but also the result of a careful reflection on the network of deep (and often unex- pected) affinities that connect the disciplines and the involved concepts. Just consider some few cases, it is worth remembering that a large portion of fractal geometry is an integral part of the qualitative theory of dynamical systems: the states of stability of certain classes of systems are instantiated from regions of the space of the phases that have fractal dimension—and which are called «strangeattractors»(or«fractalattractors»tout-court).Inaddition,significantparts of the qualitative theory of dynamic systems occupy in their turn a leading role in the formal apparatus of the physics of the emergent processes: some peculiar properties of the attractors—of all the attractors, either strange or classical—are fundamentaltodescribe/modelemergentphenomena.Amongthese,thepropertyof structuralstability(Thom1972;Stewart1993;Devaney1996)thatcaptures,onthe
