The present moment is beset by many complex challenges. Young people face living with the consequences of decisions being made largely without their consent or involvement. Centering youth voices may be part of the solution. But we need to go beyond liberal, individualist and rights-based models that pay insufficient attention to the enabling conditions of meaningful voice, to temporalities, or to schooling as institution and process. Seeking alternative conceptualizations of voice, this paper draws on Annemarie Mol's work on the 'logic of care' in relation to health services. She describes this as a ceaseless, ongoing, mutual process of attunement to the unpredictable nature of human existence, implicating a range of actors, technologies, resources, materials, meanings, and affects. This description better captures aspects of good -- responsive -- educational practice. It also resonates with recent feminist scholarship on the posthuman, new materialist and affective dimensions of everyday life and education. This can support innovative work related to youth voice, as exemplified by a research project aiming to 'attune, animate and amplify' what matters to young people in learning about sexuality. Such reconceptualizations may help us meet the challenges we face, not only in schools but those of life on a finite planet.
