We have to explain extension in itself, the extension of space must be explained as well as the rest; to presuppose it is to assume the question already solved, not to solve it.
If place considered in itself is only a part of space terminated by a surface, and space abstracted from bodies is nothing, the relation to place or to points in space must be nothing.
As all external relation, and therefore all composition of substances, is only possible in space, space must consist of as many parts as there are parts of the composite that occupies it.
Space must, however, be thought in this latter manner, for it contains an infinite number of coexisting parts.
Kant contends that since Geometry is apodeictic, space mustbe à priori and subjective, while since space is à priori and subjective, Geometry must be apodeictic 55 54.
The main result of Riemann's mathematical work was to show that, if magnitudes are independent of place, the measure of curvature of space must be constant 21 24.
It argues that, since this is true, and since geometrical judgements involve such a perception anterior to objects, space must be only the[40] form of sensibility.
If, then, this distinction should prove untenable in principle, Kant's conclusion with regard to space must fail on general grounds, and it will even have been unnecessary to consider his arguments for it.
It is only necessary to re-write his cardinal assertion in the form 'the perception of space must be nothing but the manifestation of the form of the sensibility'.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "space must" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
