The implementation of education programmes in different cultures invites the question whether we are justified in doing so in cultures that may reject the programmes' underlying principles. Are there indeed ethical principles and educational ideals that can be justified as applicable to all cultures? After a consideration of Zygmunt Bauman's postmodern rejection of the possibility of universal ethics, I cite and extend Harvey Siegel's defence of multiculturalism as a transcultural ethical ideal. I conclude the paper with a justification of the transcultural normative reach of moral principles that I have elsewhere defended as the ethics of integrity. The paper's significance lies in its justification of educational interventions founded in these principles across different cultures.
