This paper explores relationships between environment and educationafter the Covid-19 pandemic through the lens of philosophy of educa-tion in a new key developed by Michael Peters and the Philosophy ofEducation Society of Australasia (PESA). The paper is collectively writtenby 15 authors who responded to the question: Who remembers GretaThunberg? Their answers are classified into four main themes and corre-sponding sections. The first section,‘As we bake the earth, let’s try andbake it from scratch’, gathers wider philosophical considerations aboutthe intersection between environment, education, and the pandemic.The second section,‘Bump in the road or a catalyst for structuralchange?’, looks more closely into issues pertaining to education. Thethird section,‘If you choose to fail us, we will never forgive you’, focusesto Greta Thunberg’s messages and their responses. The last section,‘Towards a new (educational) normal’, explores future scenarios anddevelops recommendations for critical emancipatory action. Theconcluding part brings these insights together, showing that resultingsynergy between the answers offers much more then the sumof articles’parts. With its ethos of collectivity, interconnectedness, andsolidarity, philosophy of education in a new key is a crucial tool fordevelopment of post-pandemic (philosophy of) education.
