Just stop and think a bit. All such things as bulk, or width, you know by comparison only; comparison with familiar things. So, just for fun, go up in an imaginary balloon, about half way to that old Moon, which has hung aloft from your birth—(and possibly a day or two in addition)— and look down upon your “gigantic” city. How will it look? It is a small patch of various colors; but you know that, within that tiny patch, many thousands of your kind hurry back and forth; railway trains crawl out to far-away districts; and, if you can pick out a grain of dust that stands out dimly in a glow of sunlight, you may know that it is your mansion, your cabin or your hut, according to your financial status. Now, if that hardly shows up, how about you? What kind of a dot would you form in comparison? You must admit that your past thoughts as to your own pomposity will shrink just a bit! All this shows us that could this big World think, it wouldn't know that such a thing as Man was on it. And Man thinks that his part in all this unthinkably vast Cosmos is important! Why, you poor shrimp! if this old World wants to twitch just a bit and knock down a city or two, or split up a group of mountains, Man, with all his brain capacity, can only clash wildly about, dodging falling bricks.
