View source for Talk:Empty set

This page used to say:
"Christian scientists and others hold that it is impossible to create something from nothing, casting doubt on the existence of the empty set. However, it remains an important tool among secular mathematicians."
I have never heard this, but if I am mistaken, please add it back. I am aware that the empty set has been the subject of discussion by philosophers, and perhaps Christian philosophers in particular.  On the other hand, a very common way to specify a set is as the subset of elements of some other set which have a certain property.  For example:
{ x \in the odd integers : x is prime } is the set of odd primes, i.e., {3,5,7,...}
on the other hand
{ x \in the odd integers : x is a multiple of 2 } is the empty set {}.
This doesn't seem to be creating something from nothing to me, and the empty set arises very naturally.  Have such objections really been raised? --[[User:MarkGall|MarkGall]] 17:15, 2 September 2009 (EDT)

:::Thanks. And what is a [[unique set]], and why is this important? --[[User:Ed Poor|Ed Poor]] <sup>[[User talk:Ed Poor|Talk]]</sup> 11:55, 8 January 2010 (EST)
