This paper is inspired by, and constructed around, a number of fundamental questions that are relevant to teacher educators working within the context of the government policy initiatives and implementations that are influencing Higher Education in the UK at the present time. Using teacher education practices as sites of inquiry, and a number of figures from the work of Deleuze, the paper investigates approaches to teaching and learning that are described as having an aesthetic and ethically sensitive character. Mindful of such approaches and of the pervasiveness of policy influences, the paper also encourages a careful and thorough re-thinking of the theory and practice of teacher education as a terrain of complexity, multiplicity and interconnectedness.
