Ambiguity and Symbolic Logic

The universal use of some system of Symbolic Logic would not only enable everybody easily to deal with exceedingly complicated arguments, but would prevent ambiguous arguments. In denying the indispensability of Symbolic Logic in the former state of things, Keynes ¹ is probably alone, against the need strongly felt by Alice when speaking to the Duchess, ² and most modern logicians. It may be noticed that the Duchess is more consistent than Keynes, for Keynes really uses the signs for logical multiplication and addition of Boole and Venn under the different shapes of the words “and” and “or.”
