Rand Paul, Jeb Bush, and Hypocrisy

Apparently, Paul does not understand the concept of hypocrisy. 

After Jeb Bush admitted to smoking marijuana during his prep school days, Rand Paul called him a  hypocrite on the ground that he now opposes what he once did. 

But this accusation shows a failure on Paul's part to grasp the concept of hypocrisy.  An adequate definition must allow for moral change. One who did not attempt to live up to the ideals he now espouses ought not be called a hypocrite; the term 'hypocrite' applies to one who does not attempt to live up to the ideals he now espouses.

See my category Hypocrisy for more on this philosophically juicy theme.
