Description:

Define a Syllogism
Define Deductive and Inductive reasoning
Define a Logical Fallacy

This is the first introduction to logical thinking. We explore what a classic syllogism is by defining the parts of a logical argument. Logical fallacies are explored using the syllogism.

Syllogisms

The structure of the logical syllogism involves premise statements and a conclusion. Generally, syllogisms are made up of three statements (two premises and a conclusion). In those three statements, there are three concepts that are related (A, B, and C). The Syllogism then becomes:

Premise: A is B
Premise: C is A
Conclusion: Therefore C is B

There is also a way to introduce a negative. (Note how this changes the order of the C relationship to A and B.)
