I confess that I did have a small quibble with George Eliot on Happiness. The reason being that the very word "happy", and thus its meaning, derives from hap, happenstance, and so forth. In other words, what's happening. And thus I'm not convinced that you can completely divorce happiness from circumstances. If a person isn't rendered happy by some circumstances and sad by others, I'm not so sure they're healthy (or very empathetic).
