Query: Biased

It started well, but after some pages Strathern starts to mix very reduced information about Marx's thought with personal attacks and tu quoque (hypocrisy) appeals. Worst, the attacks consist of irrelevant information about intimate details of Marx's life that may be inaccurate or mere gossips. Sure, it is perfectly right to include biographical data in a book like this one, but it is dishonest and false to use this data only to disqualify thoughts and theories.It is very clear that the author is severely biased against this social thinker. It contains some interesting information, though. If you read this book, you should look also for a counterpart from a serious scholar.
