David Hume is widely recognised as the greatest philosopher to have written in the English language. His Treatise on Human Nature is one of the most important works of moral philosophy ever written. Hume on Morality introduces and assesses * Hume's life and the background of the Treatise * The ideas and text in the Treatise * Hume's continuing importance to philosophy
I found just reading the Hume a better introduction to his thought than this book, though it provided helpful background for understanding Hume's attacks on his contemporaries (Clarke, e.g.) who thought that reason could be the foundation of morals.
