- In this extract from Marsden’s address at the opening of Tutahi Tonu meeting house at the Auckland Teachers’ College, on 19 November 1983, Marsden writes of the supremacy of achievement in contemporary educational theory which, he observes, has its origins in the Industrial Revolution, Calvinism and Western materialistic thought. This quest for achievement, Marsden argues, mitigates against and constrains the human identity and personality, and he contends that faith in God is pivotal and the ‘foundation...for authentic existence’.
