Theories
The coupled breakdown of economic, cultural and social institutions with ecological relationships is perhaps the most common feature of collapse. The most accessible and thorough discussions of the subject are the review of the scientific anthropology literature by J.A. Tainter and the popular but thorough book of similar title by Jared Diamond. According to Jared Diamond's theory, there are five interconnected occurrences that may reinforce each other: non-sustainable exploitation of resources, climate changes, diminishing support from friendly societies, hostile neighbors, and inappropriate attitudes for change.
Joseph Tainter theorizes that societies essentially exhausted their own designs, and were unable to adapt to natural diminishing returns for what they knew as their method of survival. It matches closely Toynbee's idea that "they find problems they can't solve".

Famous quotes containing the word theories:
“We do not talk—we bludgeon one another with facts and theories gleaned from cursory readings of newspapers, magazines and digests.”
—Henry Miller (1891–1980)
“Generalisation is necessary to the advancement of knowledge; but particularly is indispensable to the creations of the imagination. In proportion as men know more and think more they look less at individuals and more at classes. They therefore make better theories and worse poems.”
—Thomas Babington Macaulay (1800–1859)
“It takes twenty or so years before a mother can know with any certainty how effective her theories have been—and even then there are surprises. The daily newspapers raise the most frightening questions of all for a mother of sons: Could my once sweet babes ever become violent men? Are my sons really who I think they are?”
—Mary Kay Blakely (20th century)
