For a contemporary perspective on J.S. Mill, quite useful. Otherwise, one of those books that, if it weren't for the topic, would be buried by history. It would be amusing indeed to see his reaction to modern women's opinion about their so-called 'mental' inferiority. I'm prejudiced against him there, though, so in more fairness... I think this is a fairly good representation of the way people approached Mill and his wife during his lifetime.
