Gotta say, I find nothing at all wrong with "Prize truth — beauty — love — seeking harmony with the infinite" and "Be not a cancer on the earth — Leave room for nature — Leave room for nature". Just because it's "hippy" doesn't mean it's a bad idea. If it were, you could get all of the hippies out of the Green parties by showing them how the Nazis were the first party with an environmental platform to take power in modern Europe.
"Seeking harmony with the infinite"? Doesns't get more Romantic than that.
