An Essay on Mediæval Economic Teaching

"An Essay on Mediæval Economic Teaching" by George O'Brien is a learned work that explores the economic ideas and rules that shaped society during the Middle Ages, a time when religion and finances were closely linked. The author believes it's important to study these old economic ideas, arguing that they're the base for today's economic thinking and that we can't fully understand current money systems without knowing where they came from. The book starts by explaining why it's valuable to study these often-ignored medieval economic teachings. O'Brien stresses that economic ideas of that time were important historically, serving not just as practical skills but as moral guidelines that showed how society worked. He also points out that there aren't many complete books about this topic in English, making his own work essential. By defining what is meant by "medieval," "economic," and "teaching," O'Brien sets the stage for a deep look at economic principles that valued moral behavior and fairness in society more than simply making money.
