THE DISCIPLINED MIND In The Disciplined Mind, Howard Gardner argues that K-12 education should strive for a deep understanding of three classical principles: truth, beauty, and goodness. Such an understanding requires mastery of the major disciplines that human beings have created over the centuries. As powerful examples of his approach, Gardner describes an education that illuminates the theory of evolution, the music of Mozart, and the lessons of the Holocaust. Far from the standardized test mentality that has gripped both policy makers and the public, Gardner envisions an education that preserves the strengths of a traditional humane education while preparing younger generations for the challenges of the future.
