Barth can be a bit circuitous in his logic, but he makes good arguments. When I saw that this collection was only 79 dollars, I couldn't pass up the opportunity to purchase it! It is a fantastic addition to anyone's theological library.
These volumes arrived the day after I purchased them - super fast! I couldn't believe the price. Look at the sales, they fluctuate up and down. The books were in perfect condition, beautiful hardbound ivory covers and clear text.
