Based on the experiences of one of the authors teaching philosophy for children in Iran, the paper asks whether respecting children's rationality, in the form of cultivating their ability and disposition to think critically, is in their best interest in an authoritarian context such as Iran. It argues that, in authoritarian contexts, respect for children's capacity for rational thought must be balanced with responsibility for their safety in their community. In other words, children's ‘best interest’ must consider children both as (...) individuals and as members of communities. The paper proposes that P4C should be used not only to teach analytic critical thinking and foster a ‘critical spirit,’ but also to help students develop the practical wisdom to judge where, when, and how best to use these skills and dispositions.
