What would you expect from the title? -An explanation and summary of Darwin's work. You get that. But very lightweight. Fully a third of this tiny book is not Darwin, but Farrington. The author takes the last third to explain Darwin's inadequacies with so-called modern hindsight, but basically turns the 'flaws' in Darwin to bring the book around to almost a repudiation of Darwin's scientific method, so that muddle-mindedness and religion can creep in the back door. I looked for a quick, articulate summary of Darwin, and got Church of England stuff way after Bishop Wilberforce.
