If we learned anything in the 21st century, it is the very newly-founded slogan that ‘anything goes’, when it comes to morality. The idea of ‘post-modernism’ in its academic and popular forms have—as this book outlines—at once rightfully removed major ideological biases, but also leaves us with moral relativism.
