Before revision: Development of Universal Logic as General Theory of Logical Systems The roots of universal logic as general theory of logical systems, may go as far back as some work of Alfred Tarski in the early twentieth century, but the modern notion was first presented in the 1990s by Swiss logician Jean-Yves Béziau.The Road to Universal Logic: Festschrift for 50th Birthday of Jean-Yves Béziau Volume I, edited by Arnold Koslow and Arthur Buchsbaum 2014 Birkhäuser pp 2-10 The term 'universal logic' has also been separately used by logicians such as Richard Sylvan and Ross Brady to refer to a new type of (weak) relevant logic.Brady, R. 2006.
