This algebra would include rules for symbolic manipulation, what he called a " calculus ratiocinator ".
3.
Wiener used the term in reference to " calculus ratiocinator ", a calculating machine constructed by Leibniz.
4.
Hence the " characteristic ", " calculus ratiocinator ", and encyclopedia form three pillars of Leibniz's project.
5.
The 17th / 18th-century mathematician Gottfried Leibniz has been credited with being the founder of symbolic logic for his work with the calculus ratiocinator.
6.
The concept is sometimes paired with his notion of a " calculus ratiocinator " and with his plans for an encyclopaedia as a compendium of all human knowledge.
7.
What Leibniz actually intended by his " characteristica universalis " and calculus ratiocinator, and the extent to which modern formal logic does justice to calculus, may never be established.
8.
The universal " representation " of knowledge would therefore combine lines and points with " a kind of pictures " ( pictographs or logograms ) to be manipulated by means of his " calculus ratiocinator ".
9.
A classic discussion of the " calculus ratiocinator " is Couturat ( 1901 : chpts . 3, 4 ), who maintained that the " characteristica universalis " and thus the " calculus ratiocinator " were inseparable from Leibniz's encyclopedic project ( chpt . 5 ).
