Understanding

Some quotes from comments at http://delong.typepad.com/sdj/2008/11/paul-krugman-se.html

It is difficult to get a man to understand something, when his salary depends upon his not understanding it.
- Upton Sinclair

A stupid man's report of what a clever man says can never be accurate, because he unconsciously translates what he hears into something he can understand.
- Bertrand Russell
