Throughout his major works, Leo Tolstoy argues that the central problem of the modern world is its delusional character. We have become delusional about the utility of science, the effects of music, the nature of love and the divine, and the inescapable reality of death. A Prophet of Modern Delusions: Tolstoy's Critique of Modernity explores Tolstoy's arguments regarding these delusions. In so doing, it illustrates the continuing relevance of Tolstoy's writings to those who desire to understand the complexities of modernity and who wish to be roused from deeply entrenched ways of thinking that may be delusional.
