I think it´s even worse than that there are some things wich will never be known: If there are some things wich will never be known...every statement that would refer to one of those things, has to be logically speaking, nonsense. And that would mean that every statement that would refer to any of those statements, would be nonsense as well. And these facts would then set off an infinite regression, infecting all of concensus reality with nonsense. Making every single statement nonsensical.
