  McTaggart was also a dedicated interpreter and champion of Hegel, and in addition to many articles on the Hegelian philosophy, he published the following books: Studies in the Hegelian Dialectic (1896, 2nd edition printed in 1922), which contains a painstaking discussion of the nature of the dialectic as well as the results achieved by its means, many of which are conclusions that McTaggart continued to argue for throughout his career, including among them that time is unreal, that existence exhausts reality, that modal notions cannot be applied to reality as a whole, and that absolute reality contains imperfections; Studies in Hegelian Cosmology (1901, 2nd edition printed in 1918), in which cosmology is understood as the discipline that applies a priori conclusions to those entities and features that we are acquainted with via experience, such as selves, the universe, and good and evil, and in which topics ranging from the ethical status of punishment and the nature of sin to whether the absolute is a person, whether human beings are immortal, or whether Hegel is a Christian are discussed in great detail; and A Commentary on Hegel’s Logic (1910), which consists of a critical commentary on the alleged logical connections between various categories by which experience must be organized and the various transitions that lead one from Hegel’s category of Being to the category of Absolute Idea.
