Ethics as a sense of joy

Holy moly this looks good: Wittgenstein's Ethical Thought by Yaniv Iczkovits. According to amazon:

He has been researching and teaching Wittgenstein and early twentieth century moral philosophy for the past ten years. Iczkovits is a published writer whose books are translated to several languages, and a political activist for human and animal rights.

You can read a few pages of the book here on Google books, and in them he thanks Eli Friedlander, Anat Matar, Stephen Mulhall, Akeel Bilgrami, Alice Crary, Cora Diamond, and James Conant, among others. He ends with thanks to his wife who, he says, made him realize that ethics is "after all, no more than a sense of joy." Sounds too good to be true.
