without being ever able to come to any stop or stint, let us enlarge it as much as we will, is that which gives us the idea of immensity.
Figure.§ 5. There is another modification of this idea, which is nothing but the relation which the parts of the termination of extension or circumscribed space have amongst themselves. This the touch discovers in sensible bodies, whose extremities come within our reach; and the eye takes both from bodies and colours, whose boundaries are within its view: where observing how the extremities terminate either in straight lines, which meet at discernible angles, or in crooked lines, wherein no angles can be perceived, by considering these as they relate to one another, in all parts of the extremities of any body or space, it has that idea we call figure, which affords to the mind infinite variety. For besides the vast number of different figures that do really exist in the coherent masses of matter, the stock that the mind has in its power, by varying the idea of space, and thereby making still new compositions, by repeating its own ideas, and joining them as it pleases, is perfectly inexhaustible ; and so it can multiply figures in infinitum.
Figure.§ 6. For the mind having a power to repeat the idea of any length directly stretched out, and join it to another in the same direction, which is to double the length of that straight line, or else join another with what inclination it thinks fit, and so make what sort of angle it pleases; and being able also to shorten any line it imagines, by taking from it one-half, or one-fourth, or what part it pleases, without being able to come to an end of any such divisions, it can make an angle of any bigness: so also the lines that are its sides, of what length it pleases; which joining again to other lines of different lengths, and at different angles, till it has wholly inclosed any space, it is evident that it can multiply figures both in their shape and capacity, in infinitum;
