What is the author's tone in The Phenomenology of Mind by Georg Wilhelm Friedrich Hegel?

The tone of this masterpiece is predominantly educational. However it really is not educational in the style of a text book. It is designed to showcase a development. Nowadays we would call this "theory" or "high theory." From our perspective, the tone is that Hegel has taken the trouble to both prepare and espouse in this book an entire theory. It is mainly a theory of knowledge, but also involves a developmental history of mankind up to the time of his creating the work.
