About this Lecture


In this module we examine the deflationary account of truth, focusing in particular on (i) the transparency property of truth in deflationism (ii) the deflationist’s rejection of a single property of truth (iii) how, through assessing the content of individual indicative propositions, we might recognise a plurality of truths across various means of enquiry (iii) Frank Ramsey’s redundancy theory of truth.


In this course Professor Simon Blackburn FBA (University of Cambridge) explores truth. In the first module, we consider the three main classical approaches to truth: correspondence, coherence and pragmatism. After that, in the second lecture we look at Charles’ Peirce’s methods of fixing belief, and the role of the scientific method in testing empirical claims. In the third module, we introduce deflationism and examine the utility of a deflationary account of truth as well as Frank Ramsey’s theory of redundancy. In the fourth module we examine various areas of enquiry in relation to truth, before finally in the fifth module, moving on to assess the value of truth in ethics and aesthetics.
