"quando orientur controversiae, non magis disputatione opus erit inter duos philosophos, quam inter duos computistas. Sufficiet enim calamos in manus sumere sedereque ad abacos, et sibi mutuo (accito si placet amico) dicere: calculemus"
— Gottfried Leibniz

January 1, 1970

The famous calculemus of Leibniz appears in several places of his writing; this is the most frequently quoted; variants are found in the Preface to his New Essays on Human Understanding, and in Dissertatio de Arte Combinatoria (1666). See R. Chrisley, Artificial Intelligence (2000), p. 14; H. Busche, Leibniz' Weg ins perspektivische Universum (1997), p. 134.
