Reading posthumanism and decolonisation diffractively towards (re)configuring an ontoepistemic approach to religion education

ABSTRACT

Student-teachers are exposed to different approaches to teaching Religion Education in South Africa. Amongst these have been the phenomenological-reflective-dialogical approach of Cornelia Roux and the empathetic-reflective-dialogical approach of Janet Jarvis. These different approaches made immeasurable contributions as they started to shift how Religion Education has been taught. The approaches are both informed by a social constructivist methodology, which riposte previous traditionalist approaches. This article questions whether these approaches, amidst the decolonial turn and the posthuman predicament, are still germane as they tend to separate ontology from epistemology. A diffractive reading of posthumanist theory and decolonial literature enabled us to bring texts in intra-action so as to problematise the colonial, capitalist and patriarchal character of existing approaches to Religion Education, both ontologically and epistemologically. This remains pivotal for a country like South Africa where colonial epistemicide prevails despite it being vehemently challenged. Our aim is to weave a text(ile), an ontoepstemic approach, to (re)configure Religion Education in support of the transformative potential of the decolonial project in South Africa. In our pursuit of ontoepistemic justice, we advocate for decolonising the Religion Education curriculum, understood as a verb, as (1) a means to critical empowerment and as (2) a complex encounter with entangled, embedded knowledges.     

“越人龙图腾祭”质疑

闻一多“越人龙图腾祭”之说根据有三 :(一 )“越人的老家本在北方” ;(二 )吴越“有关龙的节目极多” ;(三 )战国两汉有关越人崇龙的史料不少。事实上 ,土著越人并非来自北方 ,而是来自距今约 6 0 0 0年的河姆渡、良渚一带。这两地的考古发掘物中 ,鸟形物远比龙形物多得多 ,这些龙形物相对黄河中、上游 ,中国龙的发源地来说 ,其数量相对较少 ,在同一次发掘物中地位居次 ;且这些龙形物是否越器 ,龙的命名是否准确都可存疑。说到战国尤以两汉 ,那正是龙在中国逐步定型 ,被广泛认同的时代 ,近 2 0年来 ,众多的学者更附和“越人崇鸟”之说。
