We now tend to think of truth as a matter of propositions. The word ‘truth’ in its origin indicates not a proposition, but a disposition. ‘True’ (cf German treu, faithful) is related to ‘trust,’ and is fundamentally a matter of what one believes to be the case.
McGilchrist argues etymologically that truth is originally dispositional — a matter of faithfulness and trust — rather than propositional, connecting it to the relational fabric of society and selfhood.
