Throughout the history of the U.S. Navy and Marine Corps, leading officers and strategists have advocated for formal colleges and schools for naval officers but have also made the case that true naval professionalism requires a career-long dedication to learning and to self-improvement. This was the impetus behind the very founding of the U.S. Naval Institute by officers who believed that the Navy's lack of support for their education meant they needed to create their own organization for self-study and cooperative learning. Naval luminaries like admirals William Sims and Ernest King continued to campaign for self-study and the personal pursuit of professional knowledge during the twentieth century, distributing lists of suggested books for officers to read and promoting their ideas widely through speeches and published works. While recommending that officers read broadly in pursuit of individual knowledge is an important part of creating a truly educated and professional Fleet and Fleet Marine Force, it is also important for leaders in the sea services to offer mentorship and create opportunities for discourse that encourages group learning. Developing the Naval Mind serves as a how-to manual and syllabus for leaders to create and lead wardroom, ready room, and work center discussion groups across the fleet to create a more educated and professionally engaged Navy and Marine Corps.
