Apart from playing a leading role in Malta’s national educational policy development, and in the setting of the national curriculum, he continued to contribute actively in the field as chairman of the Foundation for Tomorrow's Schools, and of the Foundation for Educational Services.
Throughout his academic and philosophical career, Wain published considerably, and also established himself as a public figure of liberal views with a ready, sharp, but always civil, tongue.
His later philosophy also draws on the works of philosophers such as Michel Foucault, Jürgen Habermas and Richard Rorty.
This can be especially gauged from Wain's interest in the concept of lifelong learning, which, he maintains, should not be infected with any mania for efficient productivity in relation to political ideology, but, on the contrary, should be imbued with a broad humanistic awareness.
This corroborates Wain's understanding of democracy, which, to him, has more to do with individual maturity and responsibility and less with State hegemony or political performance.
