Leo Strauss's correspondence with German philosopher Gerhard Krüger is an invaluable source for those who seek to understand Strauss's complex and debated thought. Dating mostly from the early 1930s—a period in which Strauss went through a decisive "reorientation"—the exchange deals with several important themes and overall has a lively and straightforward style that proves to be extremely useful for the interpreter who wishes to grasp the guiding ideas of each of them.
