Accordingly the Euclidean property of space arises from the parabolic property of time.
It may be that there is reason to adopt a hyperbolic theory of time and a corresponding hyperbolic theory of space.

Such a theory has not been worked out, so it is not possible to judge as to the character of the evidence which could be brought forward in its favour.
The theory of order in an instantaneous space is immediately derived from time-order.

For consider the space of a moment M.Let {alpha} be the name of a time-system to which M does not belong.

Let A_1, A_2, A_3 etc.

be moments of {alpha} in the order of their occurrences.
