'In this work he is concerned with reducing the number of undefined terms to a minimum ... It was in this article that he introduced the symbol (left-facing E) for existence ... This paper also contains remarks on Frege's mathematical logic ...' (Kennedy, Life and works of Giuseppe Peano, p.68-69.) Frege and Peano worked independently on many of the same subjects in mathematical logic using each their own symbolism. Frege used a cumbrous two-dimensional system. It was Peano's notation which survived and was used in the 'Principia Mathematica'.
