On my way home yesterday afternoon, as is customary, I was listening to the radio. The programme I was listening to was 'Beyond Belief', which is concerned with faith and ethics.
The subject under discussion was Catholicism and I was astounded to hear one of the interviewees state that (among other things) Catholics should become less concerned with introspection and more concerned with the Truth.
Given the large number of religions, each professing to be custodians of Truth, these Truths can by definition be no more than opinions – and widely differing opinions to boot.
The only Truth can be that which is indisputable – i.e. scientific truth derived from observation, experimentation and verifiability through repeatability.
I think 'Beyond Belief' should be renamed 'All in the Mind', the name of another BBC Radio 4 programme.
