Is This An Overview? History becomes meaningful when compared to changes made through time. Changes that provide information on what was effective and what was harmful. Knowledge derived from that information can be used to prevent further errors of judgment. Knowledge derived is always biased, always selective. Knowledge is a tool, that can be used to harm humankind but also improve the human condition. How that knowledge is used is part of the social contract that enables individuals to cooperate effectively as a collective. Liberal values enable people to become aware of their biases, to challenge the views of others, and improve society through the competition of differences.
Caveats? This book is about liberalism. How liberal values are effective, and the contradictions that liberal values produced. Correcting for the contradictions. The claims and assumptions are based on the author’s liberal bias, which makes liberalism seem as the favored social ideology. There is validity to various claims made, but the claims might not be generalizable.
