This chapter focuses on theoretical pluralism and theoretical agnosticism as useful principles in my Constructivist Grounded Theory (CGT) research. In collaboration with a research team in Sweden, I have investigated student teachers’ perspectives on emotional challenges and coping. I gathered the data and was responsible for and took the lead in the analysis. In this chapter, I argue that theoretical pluralism and theoretical agnosticism are useful principles when engaging with literature and theories following a CGT approach. These concepts exemplify how grounded theories are dependent upon the researcher’s ability to make connections with multiple theories and remain open to and critical about possible connections. In this sense, research is not a neutral or value-free endeavour, but dependent upon the researcher’s contextual position, training, knowledge of the field, and experience of the phenomenon under study. In this chapter, I describe how theoretical pluralism and theoretical agnosticism have been used in my studies during different phases of a CGT study.
