Can one tell me the meaning of “-it takes time to say it but it is a primary truth-” in the context of this paragraph:

"Then, there would be progress in the scientific consideration of language if one would depart from a point which Lacan formulates very simply, and which is a kind of primary truth -it takes time to say it but it is a primary truth- that the essence of communication is the misunderstanding. "

Thank you so much.

Based purely on that extract, the author appears to be indicating the fact that ‘the essence of communication is the misunderstanding’ is a long phrase!

Thank you so much.

Hi
I 'm Mehran from Iran.
Could you tell me the meaning of " security concerns are addressed "?

if any mistake is in my text ,please let me know?

Thank you

That’s not a complete sentence, but it relates to the fact that someone has taken steps to resolve any problems with security.

thank you so much for your attention.

But i don’t know the meaning of ’ addressed ’ in this sentence.
whole sentence is:
((((It’s hoped once security concerns are addressed tourism can form the backbone of the Afghan economy))).

Once the concerns are addressed = Once the concerns are dealt with.

appreciate so much
