Logic is inherent in the universe. It is not a creation of man and is not dependent on observation or what kind of brain perceives the universe.
The laws of logic are taken to be unchanging over space and time. Logic now, is as logic was, and as logic will always be. Logic here, is as logic is there and everywhere.
Language, however, is invented. All languages (including mathematics or chemical notation or Boolean algebra or …..) must have a structure which is compliant with the logic of the universe it is used to describe. We perceive a logic in the universe and express it through the inbuilt logic of our language(s). We use the one to describe the other and they are both the same.
How not?
