Venns’s Logic of Chance (1866) was one of the earliest sustained accounts of the frequency theory of probability, since defended by von Mises and Reichcnbach. Only the frequency theory, Venn argues, can capture that range of uses of ‘probable' for which probability is something objective and measurable. His Symbolic Logic (1881) is largely derived from Boole, although the use of diagrams to illustrate the relations between sets has since become associated with Venn's name.
The later work. Inductive Logic( 1889), is largely a critical commentary on Mill. Mill’s famous methods. Venn argues, will only be applicable where the possible causes for a given effect are finite in number, and already known, which will only rarely be the case.
This line of criticism earned Venn a reputation as a sceptic about induction.
