Quite a bit, this suit has to do with the inner-workings of the environment the deck takes place in, and with mankind’s desires, what man strives toward, and the fruits of the tumultuous labours of the other Minor suits. It is a great example of how the Minor suits interlock and interact with each other. As an analog of the Coins, the Tesseracts represent economics quite a bit, commerce, trade, value. In quite a way, the Tesseracts’ interactions with the other suits is why the form of the tesseract was chosen for it. Also, in form, it’s not the worst parallel for the Coins suit.
In this suit, there is a story of a castle being built. It spends a lot of time around this building, observing its inhabitants, its construction, its inner-workings, and those outside. We see its inhabitant enjoying this castle, making it a home. In a few cards, we see the time and energy it takes to make such a castle. And we see beggars outside the walls. We see opulence, the creation of it, and those lacking it.
In a time of String Theory, a decline in poetry, mounting acceptance and evidence for higher dimensional theory, and Marvel’s Avengers questing to acquire and protect a tesseract: As a cube is a three-dimensional representation of a zero-dimensional dot, a tesseract is a fourth-dimensional version of a one-dimensional line. A zero-dimensional universe would, with no elbow-room, be a dot. Dragging that perpendicular to itself, into the first dimension, that null dimension becomes a line. Drag that line perpendicular to itself and that single-dimensional universe becomes a two-dimensional square, whose sides are made of lines. Drag that, again, perpendicular to itself into the third dimension, and we’ve got a cube, whose sides are squares. Drag our three-dimensional cube, perpendicular to itself, into the fourth dimension, and we’ve got a tesseract on our hands. A tesseract is basically a fourth-dimensional line, whose sides are cubes
Poets and artists, for instance James Joyce in “Finnegans Wake,” among others, have used the tesseract as a metaphor for emotions and other aspects of life. “Trapped in a tesseract of despair.” As a line can contain many dots, a square can contain many lines, and a cube can contain many squares, a tesseract can contain many cubes. A Dotman perceives no lines. A Lineman perceives no squares. A Squareman perceives no cubes. And we Cubemen perceive no tesseracts. This is why I love this as a metaphor. Many people often feel out of place here, in our three dimensions. Perhaps this is because we suspect that we have always actually just been a race of Tesseractpeople.
Among other literature, my friends, I urge you to go read Edwin A. Abbott’s “Flatland.” In addition to discussing dimensional theory, it addresses our blind-spots and the importance of taking others’ perspectives into account, while expanding our own.
