I can’t accept that Prufrock is striking against the lust (which would be, in this case, going against the life itself); the whole poem is so full of passion, and to give Prufrock a role of a “moral teacher” or of the “voice of conscience” would do the unjust to the poem. The lines that make me say this, are first those where he says “That is not what I meant at all. That is not it, at all.” Now, I don’t think this negation is simply something that Prufrock expects as a potential answer to his “disturbing of the universe”; it is also what he himself agrees with – that all these possible “warnings” cannot simply “squeeze the universe into a ball”, as “that is not it at all”.
I think lust is one of those things belonging to “this world”, the world of everyday life, and it falls under the things Prufrock would like not to criticize, but to subject to the burden of time. When he says that there will be time to wonder “Do I dare?”, he tells us two things:
1) we all the time stand in front of the point which, if crossed, we start daring (that’s why the second reflective questions “and, ‘Do I dare?’” – dare to act against this everyday life, to put questions, to question the time itself and the entire meaning of life;
2) the question of daring shows that Prufrock isn’t afraid of lust (to dare is, in a way, a lustful action, it’s a way of stepping over the borders of what is simply given).
Prufrock knows there’s something wrong with this usual, unreflected living, but he is, on the other hand, uncertain if questioning it would make any
sense, if it would bring anything or just miss the point. He knows in the end he wouldn’t be satisfied (”And I have seen the eternal Footman hold my coat, and snicker, And in short, I was afraid.” – afraid of not knowing the sense of everything, of life, of love, of lust, of time, of finiteness, of death).
Although it might seem that motives of Lazarus and John the Baptist are directly referring to lust and sin, lust and sin are here more symbols for something mortal, human, which cannot be understood by a simple reflection, cause “this is not it at all”.
As for the mermaids, maybe we should remember Ulysses at this point: Prufrock maybe wants to say that he’s too far in his thoughts in order to be able to hear the song of enchantment; he can see them and hear them, but he remains outside of their game. He has been among them, has played the games of love and passion, until human voices – our thoughts, reflections – wake him and he drowns.
In any case, I don’t think it is possible to put such a poem in the frame of only one interpretation. But it is wonderful to discuss its possible meanings!
