In this article, we wade through the muckiness of ethics in science, teaching, and teacher education, in the form of a generative metalogue. Grounded in Sara's experience with preservice teachers learning about ethics through a case study of a high school dissection, we contend with what it means to shift away from colonial and masculinist binaries that produce particular moralistic orientations as 'wrong' or 'right.' We contemplate what it means to attempt to teach-think-feel with ethics as 'mucky,' without diminishing attention to relations of power in science and ethics. Through our own thinking--feeling process and grappling with the ways that science and education can be simultaneously oppressive and liberating in an unfinished, complex, and interdependent world (of difference), we propose: Thinking with muckiness is ethical praxis; drawing from our own embodied resources for ethical feelingthinkingdoing is central to this praxis; and (place-conscious) powered relations in science and education must be made explicit.
