The trouble with this selection is that it just doesn't present Nietzsche as he would have presented himself
There are two reasons to buy this book: one is that it is of an aphoristic style which is not only indicative of Nietzsche's witty, ironic, deriding and even at times searingly passionate and ultimately persuasive writing style in general
another reason to buy is that reading this gives the reader not only a greater understanding of Nietzsche's philosophy, but also to be able to learn some biographical details from Nietzsche himself - not of the kind that historians might report, but moreover a psychological account of what it is like to view the events of Nietzsche's life through Nietzsche's own eyes. Much like Rousseau's 'confessions', whilst the philosophy discussed within 'ecce homo' (a part of which makes up this book) may not be substantial, it actually, by the medium of autobiography through which it is presented, it can be seen to provide a key to really getting inside the mind of this great thinker and in so doing really living out his philosophy.
Nietzsche's ability to expose so called 'ugly' truths of human nature is his lasting testament. His grim pessimism is tempered, brilliantly contrasted with, and in many ways outweighed by his boundless optimism concerning the possibilities of man in the future - of the strength and conditioning of man's soul. Nietzsche's philosophy of becoming by overcoming - the philosophy of the 'ubermensch' (superman); a great and terrifying man of 'nature' - the extension of Rousseau's 'noble savage' to the point of fault, as Nietzsche's 'ultra-man' tears free of the restraining and inhibiting factors of pity, fear, ignorance, and especially of 'common morality' and religion - is Nietzsche's lasting testament to the world, and one which led some to condemn him as the 'philosopher of fascism'. Nietzsche's books are full of fantastic metaphors and aphorisms - statements to the effect that man ought to be tested as to how much truth he could 'bear' to know. He is the man who infamously "philosophised with a hammer" (as he himself wrote in the subtitle to 'Twighlight of the Idols'), to a morally devastating effect, but always provokes a response from, challenges, and sometimes even attacks, his reader.
The reason I have gone off on such a tangent about Nietzsche's writing in general whilst supposedly writing a review of a specific product is that, if you buy this edition, this is what you are missing!
Unfortunately the edition is not only an abridgement of a longer work, but it is also one in which Nietzsche talks about himself the most: this you might think, is no bad thing since you long to know more about the man, but he is introspective and often exaggerates - pretends - to have had certain experiences, certain emotions in this text. You oughtn't to judge him just yet for falsifying his experiences, but as a one-time avid reader of Nietzsche's canon, I personally didn't enjoy ecce homo much (the work this text is extracted from), if even at all, until I had read his others, since it is those works of his mature philosophy such as Thus Spoke Zarathustra which truly provide the key which unlocks a new level of understanding of the work I am reviewing.
I am not saying that you should go out and buy the collected works, but I do have a recommendation which not only gives one a way in to Nietzsche, but also gives you an idea of his mature thought in general - I would certainly recommend 'Beyond Good and Evil', and if that is a little too long for you (around 225 pgs) then 'The Genealogy of Morality' is certainly worth a look - Nietzsche at his passionate best - no nonsense about destroying metaphysics, this book is just Nietzsche vs. common morality...
If however, you have read a brief biography (Hollingdale's is very good), or feel sufficiently acquainted with Nietzsche that you feel reading this work will benefit you as much as if you had read most of Nietzsche's books, you are probably right - but this is by no means a reason for buying this version, since it is an appropriation of two works, and it is probably best to buy the Penguin edition of 'Ecce Homo' (Hollingdale translation). Sorry but I really can't recommend this volume!
