Synopsis
Known as the best book of Karl
Mannheim, this book has considerable relevance to current concerns about
the public role of sociology. It argues that ideologies are mental
fictions whose function is to veil the true nature of a given society.
The author uses the word "ideology" in an
almost pejorative sense, reflecting a "false consciousness" based on the
thought of those in the ruling class who strive to maintain the status
quo in society. This he contrasted with "utopia," or the thought of the
oppressed who sought to improve society.
