 The main themes of the book are as follows. Scientists and philosophers sometimes present science as a unified worldview, a monolith (or a monster, depending on one’s preferences). It is not. Science is both incomplete and quite strongly disunified. It does not speak with a single voice, therefore appeals to the abstraction ‘Science’ are out of place. The ideology known as objectivism, or scientific materialism, which takes science to be our ultimate measure of what exists, is therefore ungrounded. Its defenders, who portray themselves as the defenders of Reason, are often the kind of intellectual imperialists whose attitudes and advice in the past led, or would have led, to the destruction of first-nation communities.
