‘There is no absolute truth.’ Is there any way to save this statement from its self-refuting?
The obvious riposte would be: is that statement absolutely true? Is it true, in all times and places, for all people regardless of whether or not they believe it, that there is no absolute, objective truth? If it is true, then it is an AOT (absolute objective truth) – it is the very thing it seeks to deny.
Another angle would be to tie the non-knowability of truth to our subjective, perspectivally-bound nature. Perhaps there is or isn’t AOT –but even if there was, our subjective-perspective bound nature prohibits us from knowing it. This would seem to fall prey to the same self-refutation as before – if the above is true, then it would appear that our perspective-subjective bound nature is not so binding as to prohibit us knowing that we can’t know AOT.
A more plausible objection against Truth would be linguistic – perhaps we are trapped within language. Language is notoriously slippery and ineffective at conveying information – Saussere’s ideas on the pure arbitrariness of the sign come to mind when thinking on this matter. With something as relative, culturally conditioned and arbitrary as language, how can we ever come to terms with something absolute?
