Question: How many valid forms of syllogisms are there?
The ‘matematization’ of Logic
Syllogisms have been the main form of argument studied in logic for 2000 years (from Aristotle to the
19th Century).
It was believed that all arguments, even every complex ones, could ultimately be reduced to a
series/combination of syllogisms.
However, in the 19th Century, the limitations of this theory became clear and new formalisms were
developed. The idea was to handle more complicated problems, more efficiently, with the aid of
mathematical symbolism.
Propositions
In Propositional Logic, the fundamental units are statements (propositions).
Propositions might be simple or compound.
A Simple proposition does not contain any other proposition.

A Compound proposition contains at least one simple proposition.
