Sextus Empiricus Pyrrhoniae Hypotyposes 3.12.87

[87] And for this reason, neither is the less included in the greater. For if five is included in six, as less in greater, four will be included in five, three in four, two in three, and one in two. Therefore six will contain five, four, three, two, and one, which when put together form the number fifteen, and this we conclude is included in six, if it be granted that the less is included in the greater. So likewise in the fifteen which is included in the six there is included the number thirty-five, ¹ and so on, step by step, to infinity. But it is absurd to say that infinite numbers are included in the number six; and so it is also absurd to say that less is included in greater.
