Truth is a troublesome concept, and not just for the ‘bad guys’. For hundreds of years philosophers have sought to define its meaning and understand its efficacy in relation to our world. It has undergone many incarnations including: correspondence truth, coherence truth, pragmatic truth, linguistic truth and its final nemesis, the redundancy theory. It is said that in the dead of night the post-modernists can be seen to dance on truth’s grave. But it has proved to be a most resilient idea that is still valued by most of us even if we fail to articulate just what it is. We can readily identify its antithesis – a lie or false-hood. In contemporary politics ‘propaganda’ is a word many use for false claims or downright lies.
