This paper employs Mikhail Bakhtin for a dialogic reading of dialectics, conceptualising how early childhood education (ECE) teachers' political dialogues are opened up and closed down. Explorations of 'political dialogue', or "how" teachers respond to issues they deem of political concern, is pertinent for teaching's inherently political nature. How such encounters are opened and closed has special significance for ECE teachers, who have expressed feeling professionally and politically silenced. Guided by a philosophical framing of the contradictions and jostling interplays between dialogism's in-betweenness and dialectic's one-ness, excerpts are analysed from a doctoral study involving 10 Victorian, Australian ECE teachers. This framing and analysis signal the potential ramifications of a dialectical closing down of ECE teachers' political dialogues in addition to how dialogism's in-betweenness fosters openness. Contemplating these language strategies, the paper highlights how a silencing divisiveness may transpire, prompting a need for genuine listening in the threshold in-between the self and other.
