This would be perfectly decisive, were there no medium betwixt the infinite divisibility of matter, and the non-entity of mathematical points.

But there is evidently a medium, viz.

the bestowing a colour or solidity on these points; and the absurdity of both the extremes is a demonstration of the truth and reality of this medium.

The system of physical points, which is another medium, is too absurd to need a refutation.

A real extension, such as a physical point is supposed to be, can never exist without parts, different from each other; and wherever objects are different, they are distinguishable and separable by the imagination.
