‘St Martin of Messkirch?’ assesses Heidegger's relationship with Nazism and his philosophical standing. Nazism did not inform his philosophy, nor can his philosophy be applied to it. Heidegger saw Nazism in terms of its possibilities, hoping it would bring about a spiritual renewal of life. In 1933 the evils of Nazism were not fully apparent, and Heidegger's philosophy could not secure him against the manipulations of Hitler. Heidegger's philosophy did more than adopt the ideas and problems current in his immediate environment; it asked new questions and reinterpreted other philosophers. Future philosophers will need to address these questions before the merit of his thought can be properly assessed.
