The one thing we CAN say, only quite paradoxically - is that the limits of our language are never the limits of our world unconsciously. Why is this, you may ask? This has to do with a major confusion between reason and cause of our thoughts. Science has taken up the later at the expense of the former, which is more fundamental and thus radically inaccessible. Psychoanalysis, over time (like any authentic wisdom) allows this radicalism to be accessible.
Wittgenstein is correct when he says the limits of our language are the limits of our world, consciously. But it is precisely that we believe consciously that this is our limit that gets us into trouble, into psychic pain and frustration. It was Freud that demonstrated, SHOWED, that such thoughts needed to be reconsidered since the Greeks. For what we truly don't want to know, but makes all the better when we do - is that our unconscious language knows no limits of grammar and syntax. Semantics can arise in the absence of thought in the capacity of language. After all, a picture, a visual representation, speaks a thousand words.
This much I write in my final hours in Ireland, and I believe it to not only be the case, but to be indispensable for psychoanalysis, in the way Freud intended psychoanalytic thought to manifest itself, rather than what his disciples mis-took from him, to be necessary for an understanding of psychoanalysis to re-emerge in the new world, my home country.
