1 If anyone desires an example to throw more light on this question, I shall, I 2 fear, not be able to give him any, which adequately explains the thing of which 3 I here speak, inasmuch as it is unique; however, I will endeavour to illustrate 4 it as far as possible. The nature of a circle is such that if any number of 5 straight lines intersect within it, the rectangles formed by their segments will 6 be equal to one another; thus, infinite equal rectangles are contained in a 7 circle. Yet none of these rectangles can be said to exist, except in so far as 8 the circle exists; nor can the idea of any of these rectangles be said to exist, 9 except in so far as they are comprehended in the idea of the circle. Let us 10 grant that, from this infinite number of rectangles, two only exist. The ideas 11 of these two not only exist, in so far as they are contained in the idea of the 12 circle, but also as they involve the existence of those rectangles; wherefore 13 they are distinguished from the remaining ideas of the remaining rectangles. 14 15
