The second edition of Orser’s Archaeological Thinking has been significantly updated and enhanced from the 2015 edition (CH, May'15, 52-4848). It retains the first edition's focus on using archaeological examples to promote critical thinking. Orser wisely continues to use examples from pseudo-historical or pseudoscientific theories and ideas that have become part of popular culture. In this second edition, he includes examples from the Ancient Aliens TV series, which prodigiously uses archaeological sites and discoveries to bolster its dubious contentions. The Netflix documentary Ancient Apocalypse (2022) gets a timely mention as one of the book’s examples of dubious scholarship, although a detailed critique would have provided a fine demonstration of critical thinking. Another useful addition is the up-to-date and concise account of the Kennewick Man controversy which pitted Native American religious beliefs against anthropologists. The second edition contains 10 chapters, of which four are new. Two chapters from the first edition have been dropped. Orser also provides an excellent discussion of the various schools of archaeological thought in the new chapter 7. Any library looking to build up its resources on critical thinking and archaeology will want to add this new edition to its collections. Recommended. Undergraduates and graduate students
