Summer 1

Deductive logic is a powerful tool which can help anyone to make persuasive arguments, be better at analytical thought, and to recognize a bad argument when they see one. The process of learning to make a deductive proof is useful for students who are preparing for graduate school, and careers in journalism or law.

Step by step, we will work from simple translations of statements into symbolic form, to testing the validity of interesting conclusions which might follow. By the end of this course, students will 1) be able to assess the soundness and validity of many kinds of deductive arguments; 2) have learned systems of symbolization and proof; and 3) have honed their critical reasoning skills.
