Circulus (theory)

Circulus (theory) is a way of solving problems. In circulus, you start by looking at a problem and then you ask yourself questions. You keep asking questions and use logic to figure out the answer. For example, if you wanted to know why a door is locked, you could start by asking if the door was locked by someone or if it came with a lock. If it was locked by someone, you could ask who has the key. By asking questions and using logic, you can answer the question and solve the problem!
