Take a look at Meet The Skeptic here. The book is broken down into four main sections so that you can understand and learn to engage the worldviews behind the four kinds of skepticism one-at-a-time. After reading the brief opening chapters, you don’t even have to read the for main sections in order–focus on the ideas that are the most immediate for you.
Pop-culture references are included to connect worldview concepts with everyday vernacular. Use it as a quick reference guide to brief yourself for a conversation, or as a study guide to know the areas in which you need to equip yourself further.
