Can you seek happiness and be full of joy when there is a war in Europe? Do you also have to be in pain and suffer? Professor Wes Cecil has all kinds of loose thoughts from Epicurus, the Christian ethics, Spinoza and he seeks answers. His division between happiness / pleasure / joy is perhaps just a matter of words and translation. His avoidance of pain according to Epicurus reminds me of Cassius' vessel.
Wes Cecil does not give definitive answers here, but brings material to think about.
