Skepticism plays an eminent roll in Augustine’s life and thinking. His work Contra Academicos ought to show that scepticism has to be overcome and that truth is cognizable. His early dialog ›Soliloquia‹ is almost ignored in this context; nevertheless particularly this unfinished work tries to define the term ›truth‹ as precisely as possible, but proceeds in a way that seems to characterize its author as Sceptic.
