“In your world you have a space form which is a square. And your geometers have explained that this form is but the result of cutting a cube with a plane. And that which you call a circle is but the result of passing a plane through a sphere. So that every flat，length- breadth figure which you know is but the projection of a three dimensional form. And there you have stopped.
“Yet even as a circle is a section of a sphere，so likewise is a sphere a section of a higher form whereof your senses can have no vision. And thus your world with its three dimensional men and gods is but the cross section of this super-space which you have entered. A projection，and a shadow，no more，of Reality. And this shadow you have，all save yourself，considered reality，and the substance you have named illusion.
“Look，you，Carter，and see that your universe is but the projection of a higher-dimensioned cosmos.
“And consider，in your own limited terms，the form you call a cone. Your geometers cut it with a plane. The section is a circle. They cut it with a plane that passes at a different angle，and the section is an ellipse. And again，it is a parabola whose branches sweep out through the uttermost limits of your space. And yet，it is the same cone，and there has been no change. You have but cut it at a different angle. And all，if you will，simultaneously. You have at the end no more，no less than at the beginning; and thus the ellipses，and parabolae，and hyperbolae，are illusions you call change，forgetting that their parent form is an unalterable spatial figure.
“Your world is but a section of super-space,” repeated the Space Presence, as the enlightenment sank into Carter. “And time and change are but the illusions caused in that phantom existence of yours by the shifting angle of the plane which cuts the world of reality.”
“Listen again, Randolph Carter of Arkham: you who have been so terrifyingly bewildered at the destruction of your ego, you are but one of the sections, even
