When you give a reason supporting a claim, see if you can use that same reason as evidence against your claim. For example, if you think aliens probably don't exist because you have never seen any, then can't you say, by the same logic, that the Mashco-Piro tribe probably does not exist? (It does). Seeing this error, you then revise your reason and continue to question each revision in the same way. If the process goes well, you might get to a point where you cannot refute your own argument and are more likely to have a stronger argument than if you did not go through this process. Otherwise, you might realize that your reason for supporting a claim is a poor one and find yourself reevaluating your position on an issue because of critical thought.

If you spent your life assuming "God" was the answer to all of life's biggest questions, but can no longer believe, you might have many questions that begin with the phrase, "If there is no God..." If there is no God, how did we get here? If there is no God, what's the point of life? If there is no God, where does our morality come from"? If there is no God, won't the world collapse in anarchy with murdering, coveting thy neighbor's wife, and eating shellfish? These are just some of the common questions to which there are good answers. These courses will help you build a strong foundational secular worldview based in science and reason.
