Quotation of the day

From Reinhold Baer
The main result of Gödel's paper ... can be formulated in a pointed and, hence not fully correct way as follows:
If A is a countable, consistent logical system, for example arithmetic, then there is a proposition in A which is not decidable in A (but may be decidable in extended systems).
Hurrah, logicians have also discovered diagonalisation!
Letter to Zermelo in 1931
