Before i go further, there are some things i should clarify.
I don't capitalize the letter 'i' when it is by itself, unless it starts the sentence. I just don't. And i have very good reason for it. (Whether i can convince some future publisher to listen to me, i don't know.)
English is the only language that capitalizes the first-person pronoun. French and Spanish use all lowercase letters for their pronouns. German capitalizes 'you' but leaves 'i' to its diminutive status. English is the only language that exclusively capitalizes the word 'i'. Why is that?
According to this great article in the New York Times, it comes from scribes prior to the 13th century who began capitalizing it to differentiate it from the rest of the letters. That is, without being a capital, it could be misconstrued as a vagrant letter, straying from a word to which it belongs. Yet, on that same token, the word 'a' is left untouched. There is no way to know that when i say 'a round' i didn't instead mean 'around,' unless you look at the words contextually.
If we can understand 'a round' versus 'around' and know that the letter 'a' is good enough on its own without being accentuated, why not also do the same for the letter 'i'?
Because of this precedent established over 800 years ago, we speakers of English have taken on a characteristic of the capital word 'i' that we will be hard-pressed to undo.
Western society is know for its focus on the individual, in contrast to Eastern focus on the collective, the community. I'm not going to say that this contrast was set up because of a single capital letter. Western society is formed from more than just those of us who speak English. However, I will argue that those of us in the Western world who speak English, especially Americans, are far more individual-minded than our non-English-speaking counterparts.
It's been said repeatedly in the news recently that the United States is the only wealthy, industrialized nation that does not have universal health care. Whether or not you agree with it, it does say something about our America. We are so individualistic, we don't think it's up to the collective to care for the health of the individual; it's up to each person, or family, to work that out.
Or look at our politics. Since the beginning of our country, America has been involved in 21 different wars. The only countries that have been involved in more than us are the United Kingdom and France, both of whom are middle-aged compared to us. This is probably why other countries consider America a bully, or imperialist; we enter wars, or start wars, or provoke wars across the globe, treating rival nations as if we have the right to govern them.
Again, i'm not saying that giving the word 'i' has caused all of this. It hasn't. We have. Yet our language both forms the way we think and instills in us our view of the world. Is it any wonder we are so selfish and individualistic when we place our own selves higher and taller than the others around us? Instead we say, through our language, 'he and she aren't as important as I am, and you are less than I am, too.'
We are a selfish people. Why should we capitalize the first-person pronoun the same way we would the name of God?
There are a couple solutions. We can, like Germany, flip things around. Make 'You' the word we capitalize as we leave 'i' small. Or We can equalize everyone with capitals and give every pronoun that jump in size.
I choose to leave all pronouns small, unless they fall under other rules of capitalization, just as this sentence did. So unless 'i' begins the sentence, i'm keeping him small.
(Just for the record, i've written on this before in my other blogs, but rather than copy it here, or even expand on it, i didn't even consult my previous blog. Every sentence is newly constructed, only the thoughts remain the same, but even then, some new ones entered the fray in this blog.)
