I didn't know the poem but liked it straight away. After studying the content and a few interpretations, I noticed this one. I would like to share it with you : “At one point I thought of this poem in my desire to criticize commercial usurpation of words like “freedom”: The lack of intellectual or moral integrity involved in phony creativity with the misuse of words. But that also involved recognizing my own foolishness in wanting to make words sacred. I love the way Cummings brings out contradictions in being and seeming and time with such a cleaver feel.
I now think of the poem as a bow to the present. I love you now, in the present, whatever imagination and the future might bring. “just so long and long enough.”
