(I can only assume you publish seeking criticism. Well, you are certainly going to get it here...)
Thank you for reminding us why Universities suck.
I think you have some issues with coherent writing, probably because of a misspent youth. As a contribution to your essay, I'll give it a quick edit. My edits in parenthesis.
("This paper tries" is used in consecutive sentences in your opening paragraph--Repetitive)
(The)Social Construction of Reality (theory, argument,)of Berger and Luckmann is (not)concerned (delete not) with any (form of? theoretical?--delete kind of) of knowledge being discussed in epistemology
(this sentence becomes a run-on sentence here and goes downhill quickly since the second 'is' in the sentence doesn't relate clearly to any noun. I'd suggest breaking this up into separate sentences for clarity)
(delete- but with)(Instead,) the knowledge of everyday life, as understood by Berger and Luckmann, is the kind of knowledge which enables us to know where we are, what we are doing, who we are, where we are going, how we are going to get there, what time it is, etc.
(The paragraph break in long passages to indicate different ideas is your friend. Learn to use it)
"Contemporaries are those whom merely by hearsay." (Whom what--merely by hearsay?)
(I really don't have time for more, but I truly hope you will someday achieve the knowledge that will enable you to know where you are, what you are doing, who you are, where you are going, how you are going to get there, and what time it is. Meanwhile you need an editor or a professor who believes in grade inflation)
Klaus Krippendorf needs to learn how to make paragraphs.
