Chapter 5, Part 1B - Lieh Tzu

T'ang asked the question again with more insistence, and Ko said: 'If there is nothing in space, then it is infinite; if there is something, then that something must have limits. How can I tell which is true? But beyond infinity there must again exist non-infinity, and within the unlimited again that which is not unlimited.

It is this consideration -- that infinity must be succeeded by non-infinity, and the unlimited by the not-unlimited -- that enables me to apprehend the infinity and unlimited extent of space, but does not allow me to conceive of its being finite and limited.'
