While the first abridged volume mainly discussed the rise, growth, and decline of civilizations, Toynbee’s second volume goes into depth discussing universal states, churches, and new topics like contacts between civilizations, law & freedom, etc. As with the first volume, there is a cumulative “argument” summary at the end.
Toynbee opens by discussing the belief in immortality of the universal state, with citizens evoking “their ghosts after they have proved themselves mortal by expiring” (p.6). This mirrors our contemporary attitudes in the West. He also criticizes extremely resilient civilizations like the Egyptians as being “boring and somnolent.” This likely reflects the modern emphasis on progress as opposed to stability. He viewed religion as the most important thing in life, and spends a chapter discussing how the universal church could be a higher form of society (p.94).
Heroic Ages refer to the barbarian external proletariat destroying the universal state. Barbarian power is short-lived, though, as they lack the knowledge or character to maintain complex civilization (p.136). The medieval Dark Ages was actually a creative rebirth afterwards, where they compose epic poetry based on the legends of the past.
He discusses contacts between civilizations in space and in time. The latter refers to something like the Renaissance. It’s interesting he points out that it will “occur only when an affiliated society has raised itself to the cultural level at which its predecessor was standing at the time” (p.254). He also talks about the “three-generation rule” in social cycles (~137 years), which could describe the war-and-peace cycles of Western Europe (p.284).
Throughout the book there is a strong emphasis on spirituality and philosophy, talking about people being “aloof in their hearts”, having a “deep-seated spiritual malaise”, etc, which is the mystical explanation that people like Tainter hated. The arguments are not bad in and of itself, but I read the book to gain a better sense of where we might be heading as a civilization, and how I could best prepare. To this end, I don’t think it has been very useful. Even the concluding chapters on Western Civilization seemed off the mark having been written so long ago…
For example, he falls victim to the prevailing myth of progress, where it is no longer possible “for inanimate Nature either to exterminate Mankind or even to interrupt human progress” (p.320). Though he acknowledges the possibility of decline and fall, he imagines a point where Western Civilization deals successfully with war, class-conflict, and population problems, leaving only the problem of how to spend our leisure time (p.345). Toynbee was born in 1889, and the book is a nice time-capsule of the Anglo literati of the era, including reflections on empire, the new experiment with communism, dangers of nuclear warfare, etc (written 1929 to 1955).
I read the two volume set. If you are interested in history, I would recommend a single volume edition instead. Toynbee has very flowery prose and quotes high literature, I think his works are more of literature than what we would call history today. He grew up with “Hellenic” education, though, much better than anything I had, so take my review for what it’s worth... I'll consider revisiting this work in the future when I am not so rushed for time.
