Abstract

In the second book of Soliloquia, Augustine queries: what is ‘true’ and what is ‘false’. Through the examination, Augustine (Ratio) expresses the idea that ‘true’ is that which exists. Therefore, whatever exists is true; nothing will be false. But then, what is ‘false’? This paper will first clarify that the examination of ‘false’ in Soliloquia relates to Augustine’s awareness of the problem of sin. Already in Soliloquia, Augustine finds that the soul can have in itself the cause of sin so as to be unable to have the truth. Secondly, the author examines how the epistemology of falsehood is developed in the early Augustine by examining his articles after Soliloquia, focusing on the concept of lying in De Genesi contra Manichaeos and De vera religione. This will show that Augustine's understanding of falsehood and lying is related to his soteriology. Thirdly, the paper focuses on q. 63 of De diversis quaestionibus LXXXIII, in order to clarify what Augustine thinks about the relationship between God and human soul, where Augustine notes the significance of knowing and confessing sin as the means of cooperative salvation already described in his early works.
