Eventually three major schools of feminist political theory arose, each emphasizing a distinctive subset of issues: liberal feminism, socialist feminism, and radical feminism.
First, the theory arose that God adapts customs and rites to a pagan style in order to combat paganism itself as a concession to the human condition.
Co-author, Steve Amstrup, a retired US Geological Survey polar bear researcher now affiliated with Montana-based Polar Bears Inthenational, said the "walking hibernation" theory arose with observations of bears at Canada's Hudson Bay.
The theory arose in part as a reaction to crude biological explanations of fertility declines; it rationalized them in solely socioeconomic terms, as consequences of widespread desire for fewer children caused by industrialization, urbanization, increased literacy, and declining infant mortality.
The theory arose in 1973 based on findings suggesting that depression could be avoided by suppressing mania in bipolar disorder patients (Koukopoulos et al. 2006).
We can talk about how and when that theory arose, and how it changed over time, but in doing so we are simply talking about a representation (or perhaps a lineage of related representations).
