What is the actual paradox in the Paradox of Thrift? I understand most of the reasoning, but don't understand what the actual paradox here is, as I believe there can be up to three potential paradoxes:


individuals increase savings when they should be spending more to get out of the initial recession
an increase in individual saving actually ultimately decreases total savings
what benefits an individual (increased saving during a recession) actually makes the overall economy as a whole worse off.


I'm sure it's one of the three, as they were commonly repeated when I did some research on the internet, but can't quite make out which one it is.
The Wikipedia article has several different quotations over time, though I would state the claimed paradox as a variant of (2), possibly something like 


  an increase in the rate of saving can lead to lower total savings


perhaps illustrated with a graph something like 



which suggests that the paradox seems to depend on the the combined relationships between income and savings and between investment and output, together with some macroeconomic tautologies.  If the relationships were different, or if the tautologies did not cause changes in equilibria, there might not be a paradox
