Writing Deductive Arguments

Deductive arguments begin with a general principle and reach a specific conclusion. They develop that principle with logical arguments that are supported by evidence—facts, observations, the opinions of experts, and so on. Keep in mind that no single structure is suitable for all deductive (or inductive) arguments. Different issues and different audiences will determine how you arrange your ideas.

In general, deductive essays can be structured in the following way:

INTRODUCTION Presents an overview of the issue States the thesis
BODY Presents evidence: point 1 in support of the thesis
Presents evidence: point 2 in support of the thesis
Presents evidence: point 3 in support of the thesis
Refutes the arguments against the thesis
CONCLUSION Brings argument to a close Concluding statement reinforces the thesis
