The litlle argument of "Who are we to say?"

I love a few books, one of my favorites being Flowers for Algernon by Daniel Keyes. It would be grand if you would take the time and read it. It was in the belly of this certain book that I found yet another lost puzzle piece to human wisdom. I do not care to discuss the story, but I must give you a quick glimpse of the background to what i am to tell you. Here it goes, Charlie is a mentally disabled man in his thirties who undergoes an operation  in order to become smart. Now I shall sin and rip a few words out of context, so bear with me... At the hight of his smartness Charlie is standing in front of the mirror and sees his  his old self, he talks to this reflection, saying, "Who am I to say my light is better than your darkness, who am I to say?" That is what so many people forget these days, or rather not forget, they chose not to be humble. They might argue that to be humble is to be weak, I believe that to be humble is to be human. To be able to ask yourself "who am I?", and answer with some carefully prepared and highly detailed answer is not the way of a mature man, as many would say, it is rather foolish and naive thing to say. The question is hard to answer because it does not require one , and yet we try... Aside from those who say they know everything are those who say they know nothing, their answer of who they are may contain words such as nothing and nobody. But still who are they to say? I say we do not and cannot know. And there is beauty to not knowing everything  but one must posses a power to humble themselves, at least for a moment, for in not knowing you find wisdom and the more puzzle pieces you find the clearer the picture is.
