     That is to say, it is the Analogue of Space, not in the sense in which we formerly regarded Space as the negation of Matter; but in the sense of Infinite Dimensionality, or of Dimensionality in all directions, as a vague generalization from the three spatial dimensions Length, Breadth, and Thickness.

     This often happens, for example, when a two-dimensional solution is obtained for data whose appropriate dimensionality is higher.
