It is one thing to know that there are more than three dimensions; it is another thing altogether to see them. It isn’t so hard to see up to nine dimensions, but humans rarely attempt the feat. They are happy enough to see in three. Many stick to two. Some are content with one and travel through life the way a subway moves through the earth. They are always on some line. Here is their stop. Work and home. Home and work. Back and forth, with a magazine read, perhaps, between the two.
