“You will see this for yourself if you will come with me into the state of three dimensional time.”

“What’s that?” said Mr. Spalding, deeply intrigued. “That,” said the philosopher, “is time which is not linear succession, time which has turned on itself twice to take up the past and future into its present. For as the point is repeated to form the line of space, so the instant is repeated to form the linear time of past, present, future. And as the one-dimensional line turns at right angles to itself to form the two-dimensional plane, so linear or one-dimensional time turns on itself to form two-dimensional or plane time, the past-present, or present-future. And as the plane turns on itself to form the cube, so past-present and present-future double back to meet each other and form cubic time, or past-present-future all together.

“This is the three dimensional state of consciousness we shall have to think ourselves into.”

“Do you mean to say that if we get into it we shall have solved the riddle of the universe?”

“Hardly. The universe is a tremendous jig-saw puzzle. If God wanted to keep us amused to all eternity, he couldn’t have hit on anything better. We shall not be able to stay very long, or to take in all past-present-future at once. But you will see enough to realize what cubic time is. You will begin with one small cubic section, which will gradually enlarge until you have taken in as much cubic time as you can hold together in one duration.

“Look out through that window. You see that cart coming down the street. It will have to pass Herr Schmidt’s house opposite and the ‘Prussian Soldier,’ and that grocer’s shop and the clock before it gets to the church.

“Now you’ll see what’ll happen.”

What Mr. Spalding saw was the sudden stoppage of the cart, which now appeared as standing simultaneously at each station, Herr Schmidt’s house, the inn, the grocery, the clock, the church and the side street up which it had not yet turned.
