Study Notes

Introduction to Statements and Logical Connectives

In logic, we deal with statements. A statement is a declarative sentence that is definitively either true or false, but not both. It's not a question, a command, or an opinion.

  • "The sky is blue." (This is a statement; it's true.)
  • "Close the door." (Not a statement; it's a command.)
  • "What time is it?" (Not a statement; it's a question.)
  • "Chocolate ice cream is the best." (Not a statement; it's an opinion, and its truth value isn't universal.)
