Without Lifting A Finger

Seemed like a natural switch: from Physics to Metaphysics. Physics was ok but getting a bit tedious. *      Further, of the ways in which we prove that the Forms exist, none is convincing; for from some no inference necessarily follows, and from some arise Forms even of things of which we think there are no Forms. For according to the arguments from the existence of the sciences there will be Forms of all things of which there are sciences and according to the 'one over many' argument there will be Forms even of negations, and according to the argument that there is an object for thought even when the thing has perished, there will be Forms of perishable things; for we have an image of these. Further, of the more accurate arguments, some lead to Ideas of relations, of which we say there is no independent class, and others introduce the 'third man'.

     (5) Further, too, if it is itself and existent, where will it be? Zeno's difficulty demands an explanation: for if everything that exists has a place, place too will have a place, and so on ad infinitum.

Belief in the existence of the infinite comes mainly from five considerations:      (1) From the nature of time -- for it is infinite. (2) From the division of magnitudes -- for the mathematicians also use the notion of the infinite. (3) If coming to be and passing away do not give out, it is only because that from which things come to be is infinite. (4) Because the limited always finds its limit in something, so that there must be no limit, if everything is limited by something different from itself. (5) Most of all, a reason which is peculiarly appropriate and presents the difficulty that is felt by everybody -- not only number but also mathematical magnitudes and what is outside the heaven are supposed to be infinite because they never give out in our thought.      The last fact (that what is outside is infinite) leads people to suppose that body also is infinite, and that there is an infinite number of worlds. Why should there be body in...
