Logic is the study of arguments. By arguments, I don’t mean bickering. The word argument came from the Latin word argumentum, which meant evidence. An argument was originally the evidence you used to prove or disprove something. Logic is the study of how to use evidence to prove or disprove conclusions.
Before you can study logic, you need to know some basic grammatical concepts. That’s because grammar is the study of the structure of meaningful sentences, and arguments are made up of sentences. Yesterday, I gave a link to an excellent resource for studying English grammar. Today, I’m posting a link to an Internet resource for people who want to study logic. It’s from Lander University in Greenwood, South Carolina. I strongly recommend that people go through the grammar review before they start studying logic!
