targets Löwith's argument that progress is the secularization of Hebrew and Christian beliefs and argues to the contrary that the modern age, including its belief in progress, grew out of a new secular self-affirmation of culture against the Christian tradition." Wolfhart Pannenberg, a student of Löwith, has continued the debate against Blumenberg. Charles Taylor in "A Secular Age" challenges what he calls 'the subtraction thesis' – that science leads to religion being subtracted from more and more areas of life. Proponents of "secularization theory" demonstrate widespread declines in the prevalence of religious belief throughout the West, particularly in Europe.Bruce, Steve. God is Dead: Secularization in the West. (2002) Some scholars (e.g., Rodney Stark, Peter Berger) have argued that levels of religiosity are not declining, while other scholars (e.g., Mark Chaves, N. J. Demerath) have countered by introducing the idea of neo-secularization, which broadens the definition of secularization to include the decline of religious authority and its ability to influence society. In other words, rather than using the proportion of irreligious apostates as the sole measure of secularity, neo-secularization argues that individuals increasingly look outside of religion for authoritative positions. Neo-secularizationists would argue that religion has diminishing authority on issues such as birth control, and argue that religion's authority is declining and secularization is taking place even if religious affiliation may not be declining in the United States (a debate still taking place). Finally, some claim that demographic forces offset the process of secularization, and may do so to such an extent that individuals can consistently drift away from religion even as society becomes more religious. This is especially the case in societies like Israel (with the ultra-Orthodox and religious Zionists) where committed religious groups have several times the birth rate of seculars. The religious fertility effect operates to a greater or lesser extent in all countries, and is amplified in the West by religious immigration. For instance, even as native whites became more secular, London, England, has become more religious in the past 25 years as religious immigrants and their descendants have increased their share of the population. Across the board, the question of secularization has generated considerable (and occasionally heated) debates in the social sciences. Regional developments United States 1870–1930. Christian Smith examined the secularization of American public life between 1870 and 1930. He noted that in 1870 a Protestant establishment thoroughly dominated American culture and its public institutions.
