Both the use of logic and probability theory are
heavily applied in many, if not all, areas and industries due to what they can
offer. Logic is well known for enabling one to comprehend many things which
include intentions, behavior, beliefs, intelligence, knowledge and languages,
and to create algorithms designed to solve simple and complex problems.
Probability theory is specifically designed to address uncertainty, which
uncertainty exists everywhere. Through pairing probability theory with other disciplines
is one able to address uncertainty in other fields. Combined, logic and
probability theory enable one to address complex problems in law. This paper
will first describe logic and probability theory, then address their
application to legal reasoning. Accordingly, I argue that logic and probability
theory can be used to validate thoughts and arguments made by lawyers and
judges, allowing for better understanding of the validity, coherency,
truthfulness of their arguments, and the correctness of the statements and
decisions made by them.
