Beiser does an excellent job here giving the reading a comprehensive overview of Hegel's life, work, and major concepts. This is definitely the best introduction to Hegel that I've yet read. As you'll see if you try to read plain ol' Hegel himself, his prose is unwieldy and his translations are even worse (with a few exceptions). Simply put, a secondary source is definitely the way to approach Hegel if you're new to the field, or if life is just too short to wade through, say, his multi-volume work on aesthetics!
Beiser writes in an authoritative, but inviting voice. While he could doubtlessly run circles around readers, he choses to place emphasis on communication. That is not to say that he presents a dumbed-down version of Hegel. Just that he doesn't needlessly complicate ideas that are themselves complicated. In fact, he does a markable job untangling some of Hegel's more difficult and widely misunderstood concepts.
Beiser handles his topic in the best way possible. While adapting Hegel to current times would make him easily applicable to modern times, Beiser chooses not to put words in Hegels mouth, but to let him speak in the way that he did and on the topics that he covered. This more historical approach will require a little more effort on the part of the reader, but it is ultimately more useful.
While this book will be useful to a wide range of people, it's almost definitely not the only Hegel book you'll ever need. If you get serious, naturally you'll want to read some Hegel for yourself. Even if you intend to read Hegel directly, this is still a worthwhile purchase. I've always found reading easier if I had some idea what to look for. This introduction will allow you to key in on the important areas of Hegel while helping you avoid getting trapped in the difficult or overly wordy sections.
If you want more depth on certain issues (in my case it was Hegel's aesthetics) without necessarily reading a lot of Hegel yourself, Beiser provides plenty of references to excellent secondary sources. This is perhaps one of the best reasons to buy the book - Beiser has clearly read not only all of Hegel, but a wide range of secondary and tertiary material on Hegel.
Rather than attempt to summarize Beiser's views or, worse yet, attempt to summarize Hegel's views, I'll let you discover it for yourself. Hegel is well worth reading and this is an informative way to start.
