What is philosophical about the practice Philosophy for Children (P4C)? In this open access book, the authors offer a surprising answer to this question: a practitioners contemplation of the potentiality to speak, or what can be called infancy. Although essential to the experience of language, this most basic and profound capacity is often taken for granted or simply instrumentalized for the educational purposes of developing critical, caring, or creative thinking skills in the name of democratic citizenship. Against this kind of instrumentalization, the authors radical reconceptualization of P4C focuses on the experience of infancy that can take place through collective inquiry. The authors Philosophy for Infancy (P4I) emerges as a non-instrumental educational practice that does not dictate what to say or how to say it but rather turns attention to the fact of speaking. Referencing critical theorist Giorgio Agambens extensive work on the theme of infancy, the authors philosophically engage the core writings of Matthew Lipman and Ann Sharp, foundational scholars in the P4C tradition, to rediscover this latent potentiality in the original P4C program that has yet to be developed. Not only does the book provide a new theoretical basis for appreciating what is philosophical in Lipman and Sharps formulations of P4C, it also provides a unique elucidation of key concepts in Agambens worksuch as infancy, demand, rules, adventure, happiness, love, and anarchywithin a collective, educational practice. Throughout, the authors offer applications of P4I that will provide anchoring points to inspire educators to return to philosophical experimentation with language as a means without end.
