“Knighthood lies above eternity; it doesn’t live off fame, but rather deeds.”

This was an epitaph Fields proposed for himself in a 1925 article in Vanity Fair. It refers to his long standing jokes about Philadelphia (his actual birthplace), and the grave being one place he might actually not prefer to be. This is often repeated as "On the whole, I'd rather be in Philadelphia.", or "All things considered, I'd rather be in Philadelphia." which he might have stated at other times. It has also sometimes been distorted into a final dig at Philadelphia: "Better here than in Philadelphia." Fields' actual tomb at Forest Lawn in Glendale, California simply reads "W. C. Fields 1880–1946".

For the glory of wealth and beauty is fleeting and perishable; that of the mind is illustrious and immortal.

Paraphrased variant: I would rather live and love where death is king than have eternal life where love is not.
At A Child's Grave (1882)
Context: No man, standing where the horizon of a life has touched a grave, has any right to prophesy a future filled with pain and tears. It may be that death gives all there is of worth to life. If those we press and strain against our hearts could never die, perhaps that love would wither from the earth. Maybe this common fate treads from out the paths between our hearts the weeds of selfishness and hate, and I had rather live and love where death is king, than have eternal life where love is not.
