sam1972's review
5.0
A quintessential argument for moral anti-realism, and a staple in the curriculum of meta-ethics. Part one is the most famous, where Mackie rejects the existence of objective ethics. Part two is dedicated to synthesizing a new, non-objective morality out of the classic theories of consequentialism, deontology, and virtue ethics. Part three then applies this newley-constructed ethical framework to modern philosophical controversies (or, at least issues that *were* modern when the book was written).
