The contemporary academic study of religion has its roots in conceptual and theoretical structures developed in the early to mid-20th century. A particularly important example of such a structure is the concept of the “numinous” developed by the theologian and comparativist Rudolf Otto (1869–1397) in his work, The Idea of the Holy: An Inquiry into the Non-Rational Factor in the Idea of the Divine and its Relation to the Rational (1923). Building on the work of Immanuel Kant (1724–1804), Friedrich Schleiermacher (1772–1834), and Jakob Fries (1773–1843), Otto developed the concept of the numinous—a “category of value” and a “state of mind”—as a way to express what he viewed as the “non-rational” aspects of the holy or sacred that are foundational to religious experience in particular and the lived religious life in general. For Otto, the numinous can be understood to be the experience of a mysterious terror and awe (Mysterium tremendum et fascinans) and majesty (Majestas) in the presence of that which is “entirely other” (das ganz Andere) and thus incapable of being expressed directly through human language and other media. Otto conceives of the concept of the numinous as a derivative of the Latin numen, meaning “spirit,” etymologically derived from the concept of divine will and represented by a “nodding” of the head. Otto argues that understanding the numinous in a satisfactory way requires a scholar to draw upon their own experience of religious sentiments, given its non-discursive and direct nature; this becomes a point of contention among later secular scholars of religion. In later works, such as Mysticism East and West: A Comparative Analysis of the Nature of Mysticism (1932), Otto gives numerous examples of the ways in which the concept of the numinous can be applied cross-culturally to traditions beyond Christianity, such as Hinduism and Buddhism.
Otto’s theories regarding the numinous have been extremely influential in the development of the academic study of religion in the 20th and 21st centuries, as evidenced by the impact they had upon scholars such as Carl Jung, Mircea Eliade, and Ninian Smart, whose works were instrumental in the formation of religious studies as a discipline. Jung cites the concept of the numinous extensively with regard to his theories on the breakthrough of unconscious material into conscious awareness. Eliade’s work The Sacred and Profane: The Nature of Religion (1959) takes Otto’s concept of the numinous as a starting point in the development of its own theory; Eliade’s use of the category of the “sacred” might be considered derivative of Otto’s larger conception of the “holy” (das Heilige). Eliade’s work, like Otto’s, has been extensively criticized for postulating a sui generis nature of both the numinous and the sacred, which are viewed by Eliade as irreducible to other phenomena (historical, political, psychological, and so forth). Smart’s influential “dimensional analysis” theory and his scholarship on the topic of world religions is highly informed by his utilization of Otto’s theory of the numinous within the contexts of his cross-cultural reflections on religion and the development of his “two-pole” theory of religious experience. The concept of the numinous continues to be theorized about and applied in contemporary academic research in religious studies and utilized as part of a framework for understanding religion in university courses on world religions and other topics in the academic study of religion. In part through the work of Eliade, Smart, and other scholars—Otto included—who have found a popular readership, the term has been disseminated to such a degree as to find common usage in the English language and popular discourse.
The Sōka Gakkai is a lay Buddhist movement, originating in Japan, that bases its religious practice and worldview on the Lotus Sutra-centric teachings of the Kamakura-era priest Nichiren (1222–1282). Following Nichiren, members of the Sōka Gakkai consider the practice of reciting Namu-myōhō-renge-kyō—the Daimoku, or title of the Lotus Sutra—to a copy of a character mandala (Gohonzon) originally inscribed by Nichiren to be the fundamental means for attainment of enlightenment. Also modeling themselves on Nichiren, the membership takes an active interest in the social and political realities of this world. In Japan, this engagement has taken various forms, including electoral support for a political party made up largely of Sōka Gakkai members, and globally, as activities in the fields of nuclear disarmament, sustainable development, human rights education, and humanitarian assistance.
Founded in 1930, the organization was suppressed during World War II. In the postwar era, its rapid growth, driven by a campaign of aggressive proselytization, as well its ongoing involvement in politics, has generated considerable controversy within Japanese society. Even as the organization has matured institutionally, and in its relations with other faith traditions, an exclusive commitment by members to a single faith practice makes it an outlier within the Japanese religious landscape.
The Sōka Gakkai in Japan currently claims some 8.27 million member families, making it the nation’s largest and most active religious movement. Outside Japan, under the rubric of Sōka Gakkai International (SGI), official statistics give membership totals of 1.75 million in 192 countries and territories, with 94 organizations incorporated under local national laws. More than half of the membership outside Japan—slightly more than 1 million—are said to be in Asia and Oceania, with South Korea, Taiwan, Hong Kong, and Singapore among the sites of large and active memberships. Other countries with significant national movements include Brazil, the United States, India, and Italy.
While the Sōka Gakkai was originally associated with the Nichiren Shōshū sect, long-standing tensions over the respective roles of priesthood and laity came to a head in a decisive schism in 1991, since which the two groups have pursued independent paths. Following the schism, the Sōka Gakkai has given more central emphasis to the “mentor-disciple relationship,” in particular as this relates to the first three presidents of the organization: Makiguchi Tsunesaburō (1871–1944), Toda Jōsei (1900–1958) and Ikeda Daisaku (1928–).
Religion has always been a contextually based phenomenon, particularly in urban space. Cities of every size, in every period, and in every region of the country have been defined by the towers and spires of faith traditions. They have mapped cities, providing anchors to religionists who worship there, and contributing to the construction of civil society and a sense of place. Communities of faith have drawn migrants and immigrants to settle in a particular place and provided resources for adaptation and integration. Houses of worship have often defined neighborhood identities and become progenitors of social capital beyond their walls. Increasingly the physical and social forms of religion are becoming more diverse—different accents, practices, music, dress, and even scents pour into and out of houses of worship that may not be grand old structures but more modest structures built for other purposes, blending into the cityscape. Still, religion is influential in shaping its context both spatially and socially.
But the relationship is reciprocal, as context acts on the questions, meanings, and practices of faith groups as well. The city has occupied the religious imaginations of many traditions as an ambivalent symbol, seen as both the locus of depravity and of redemption. Out of these imaginaries religious questions, meanings, practices, and forms of engagement have been shaped. Further, the economic, political, social, and institutional dynamics of the urban space impact the practice and understanding of religion, and how it is expressed and lived out in everyday life.
The interaction of religions and urban space—what can be described as a dynamic synapse in a human ecology—is emerging as a focus of exploration in understanding how cities work. Although religion is often overlooked by many urban theorists, researchers, planners, developers, and governments, it is gaining fresh attention by scholars. Drawing on major schools of urban theory—particularly the modernist Chicago School and the postmodern L.A. School of Urbanism—the spatial dimension of urban religion is being analyzed in research projects from a growing number of contexts. Theoretical and empiric work is enabling a deeper understanding of the relationship of religion and cities; they cannot be considered in isolation. Religious agency cannot be exaggerated or romanticized but should be considered as what two researchers have called “one of the ensemble of forces creating the new American metropolis” (Numrich, Paul D., and Elfriede Wedam. Religion and Community in the New Urban America. New York: Oxford University Press, 2015.). In the same way, faith groups of all traditions and dimensions do not exist in isolation of their context as bubbles in city space. The intersection of space and urban religion is complex, especially as both religion and cities are in the midst of great change in the 21st century.
Thought experiments are basically imagined scenarios with a significant experimental character. Some of them justify claims about the world outside of the imagination. Originally they were a topic of scholarly interest exclusively in philosophy of science. Indeed, a closer look at the history of science strongly suggests that sometimes thought experiments have more than merely entertainment, heuristic, or pedagogic value. But thought experiments matter not only in science. The scope of scholarly interest has widened over the years, and today we know that thought experiments play an important role in many areas other than science, such as philosophy, history, and mathematics. Thought experiments are also linked to religion in a number of ways. Highlighted in this article are those links that pertain to the core of religions (first link), the relationship between science and religion in historical and systematic respects (second link), the way theology is conducted (third link), and the relationship between literature and religion (fourth link).
