From+what+I've+tasted+of+desire+I+hold+with+those+who+favor+fire.

Let me just say, this is one of my favorite poems! When you think of passion, does fire not pop into your head? I think that is why Robert Frost said that he would rather die in an inferno, than in an icy tundra. It's very romantic, actually, it reminds me of the book; "Like Water for Chocolate". In the end, Tita and Pedro die in an all-consuming blaze, because they feel so much love and passion towards each other. Fire could be a metaphor for desire in this poem, so the poet is saying that he would rather die in love, than to die cold.
