"for [anything] other than mathematical contents due to the potential different sociological aspects of alien receivers". Ollongren's LINCOS The concept astrolinguistics in scientific research was coined as such, also with a view towards message construction for ETI, in 2013 in the monograph Astrolinguistics: Design of a Linguistic System for Interstellar Communication Based on Logic, written by the astronomer and computer scientist Alexander Ollongren from the University of Leiden (the Netherlands). This book presents a new Lingua Cosmica totally different from Freudenthal's design. It describes the way the logic of situations in human societies can be formulated in the lingua, also named LINCOS. This astrolinguistic system, also designed for use in interstellar communication, is based on modern constructive logic – which assures that all expressions are verifiable. At a deeper, more fundamental level, however, astrolinguistics is concerned with the question whether linguistic universalia can be identified which are potentially useful in communication across interstellar distances between intelligence species. In the view of the new LINCOS these might be certain logic descriptions of specific situations and relations (possibly in an Aristotelian sense). Kadri Tinn's (Astronomy for Humans) review of Ollongren's book recognised that aspect – she wrote: See also Alien language Alien language in science fiction References Further reading LINCOS: Design of a Language for Cosmic Intercourse, Part I, by Hans Freudenthal, Professor of Mathematics and Logic, University of Utrecht, The Netherlands, 224 pp. North Holland Publishing Company, Amsterdam 1960.
