‎Exceedingly scarce first edition, off-print with own pagination also, of this very important article by one of the four greatest logicians ever, the Polish-American Alfred Tarski.Tarski's theory of definability, which he presents in this article, belongs to one of his main contributions to logic. Tarski here distinguishes between groups of concepts within the methodology of the deductive sciences: 1) concepts such as ""axiom"", ""theorem"", ""rule of inference"", ""proof"", and 2) ""primitive (undefined) concept"" (or ""primitive term""), ""definable concept"", ""rule of definition"", ""definition"". ""A far-reaching parallelism can be established between the concepts of the two groups: The primitive concepts correspond to the axioms, the defined concepts to the derivable sentences, the process and rules of definition to the process and rules of proof."" (English translation of the article, 1956, p. 296). Until this article was written, nothing on the subject of methodology of deductive sciences had primarily dealt with the concepts of the first group, but, as Tarski himself states, ""in considering the second group of concepts many interesting and important problems force themselves upon us, some of which are quite analogous to those which arise in connection with the first group."" (Introduction, English translation, 1956, p. 296). Two problems are discussed within this domain: the problem of the definability and the mutual independence of concepts, as well as the problem of the completeness of concepts of an arbitrary deductive theory.Tarski (1901-1983) has contributed seminally to the fields of mathematics and logic in a number of ways, and together with Frege, Russell and Gödel, he now ranks as the most important contributor to the field of logic. He is thus considered one of the four greatest logicians of all times. ‎

‎Order into Action. How Large-Scale Concepts of World-Order determine Practices in the Premodern World‎

‎, Brepols, 2022 Hardback, 332 pages, Size:156 x 234 mm, Illustrations:5 b/w, 16 col., Language: English. ISBN 9782503590462.‎

‎Summary The construction and application of models that order complex phenomena such as 'the world' is not a 'neutral' activity: theoretical models and ideas help us to perceive and categorize the information conveyed by experience and tradition alike; in turn, they also influence the behaviour and actions of individuals and groups. Collecting a global series of case studies on premodern societies, this volume proposes new approaches to research into premodern models of world-order and their effects. With its focus on the period between c. 1300 and 1600, it seeks to open up fresh perspectives for premodern Global History and the analysis of phenomena of transcultural contact and exchange. Focussing on religious, political, and geographical ideas and models, the contributions explore whether and how large-scale concepts influenced or even determined concrete actions. The examples include socio-religious concepts (Christianity, terra paganorum, d?r al-?arb), political concepts (empire) and geographical notions. A special section is dedicated to comparative insights into societies in Sub-Saharan Africa, Australia, and pre-Columbian America. Taken together, the contributions underline the importance and effects of historically shaped cultural traits in the long term.

‎Book of Colour Concepts. 45th Ed.‎

‎, Taschen, 2024 Hardcover, 512 pages, 15.6 x 21.7 cm, Multilingual (English, French, German).The Book of Colour Concepts. 45th Ed. ISBN 9783754401248.‎

‎The human history of color, The earliest forms of human creativity in carvings, markings, and cave paintings bear witness to humanity's engagement with color. Almost as old as these examples is the desire to assign structure, order, and meaning to this universal yet elusive concept, and it is this fascination that unites the works compiled in this expansive edition. Gathering over 65 rare books and manuscripts from a wealth of institutions, including the most distinguished color collections worldwide, The Book of Colour Concepts takes the reader on a chromatic odyssey across four centuries and over 1,000 images of luscious wheels and globes, painstakingly collated charts, and meticulous diagrams, many of them newly photographed exclusively for this edition. Some of these concepts provide exhaustive taxonomies of color, while others reflect upon the relationship of color and music, or the affinities between color and human emotions. Seminal works of color theory, such as Isaac Newton's Opticks and Johann Wolfgang von Goethe?s hugely significant Zur Farbenlehre, are shown alongside rare and unfamiliar contributions, including the theosophical color systems of Charles Webster Leadbeater and Annie Besant, the comprehensive color dictionary of Aloys John Maerz and Morris Rea Paul, and the patchwork combinations of the Japanese costume designer and artist Sanz Wada. also bring many intriguing and often overlooked works by women into the spotlight, including the radically inventive color ?blots? of the English flower painter Mary Gartside and a botanical notebook by the pionieering spiritualist Hilma af Klint. The color systems that make up this edition are contextualized by introductory essays from editor Alexandra Loske and co-author Sarah Lowengard, while authoritative texts from the editor on the works reproduced set out each concept in further detail. Illuminating the history of color in all its shapes and forms, The Book of Colour Concepts offers a chromatic chronology unparalleled in scope.‎
