Introduction.

This article, titled "Introduction," discusses the concept of splitting as a defense mechanism in psychoanalysis. The concept was first elaborated by Melanie Klein in her 1946 article, "Notes on Some Schizoid Mechanisms." Splitting refers to the separation or division of positive and negative experiences within the developing ego. Since Klein's formulation, other theorists have explored this concept in relation to borderline personality functioning, the development of endopsychic structure, and responses to unbearable experiences. The article highlights the relevance of splitting in understanding issues such as othering, whiteness, racism, and socio-cultural divides. The authors have invited various psychoanalytic thinkers to reflect on their use of the concept in clinical practice and in understanding the current world and professional communities.
