A Reaction

[Priest gives full details] Priest's idea is that Closure is when a set is announced as complete, and Transcendence is when the set is forced to expand. He claims that the two keep coming into conflict.


The 8 ideas from 'The Structure of Paradoxes of Self-Reference'

The least ordinal greater than the set of all ordinals is both one of them and not one of them [Priest,G]
The next set up in the hierarchy of sets seems to be both a member and not a member of it [Priest,G]
The 'least indefinable ordinal' is defined by that very phrase [Priest,G]
'x is a natural number definable in less than 19 words' leads to contradiction [Priest,G]
By diagonalization we can define a real number that isn't in the definable set of reals [Priest,G]
If you know that a sentence is not one of the known sentences, you know its truth [Priest,G]
There are Liar Pairs, and Liar Chains, which fit the same pattern as the basic Liar [Priest,G]
Typically, paradoxes are dealt with by dividing them into two groups, but the division is wrong [Priest,G]
