In research on Augustine, Peter Brown’s paradigm of ‘two Augustines’ has been widely used. According to Brown, Augustine experienced a shift from optimism to pessimism. In his earlier works, Augustine held that humans could achieve happiness in this life by reason. In contrast, in his later works, Augustine emphasised grace, original sin and the imperfection of life. Against Brown’s framework, this paper argues that Augustine does not experience a pessimistic turn. Augustine holds that humans can achieve happiness through faith, hope (...) and love.Contribution: This article explores Augustine’s theory of happiness and revises the ‘two Augustines’ paradigm. On the one hand, Augustine does not deny the freedom of will. On the other hand, Augustine is confident in happiness through faith, hope and love. (shrink)
