Book excerpt: In his previous bestseller Memorize the Faith!, Kevin Vost rediscovered a memory method invented by the ancient Greeks and perfected by medieval scholars, and showed twenty-first-century Catholics how to use it to recall everything from the Ten Commandments to the Seven Deadly Sins. Now, in Memorize the Reasons!, Dr. Vost shows you how to remember information you need to explain and defend the Catholic Faith. Often when we're challenged by non-Catholics -who always seem to be able to quote chapter and verse -we stumble, and later think regretfully of what we might have said.
