To be or not to be, that is the question.
You may say that this means the same as 'What is just now occupying my attention is the comparative disadvantages of continuing to live or putting an end to myself.' And for practical purposes—the purpose, for example, of a coroner—it does. But as the second version altogether misrepresents the speaker at that moment of his existence, while the first does represent him, how can they for any but a practical or logical purpose be said to have the same sense? Hamlet was well able to 'unpack his heart with words,' but he will not unpack it with our paraphrases.
VERSIFICATION
These considerations apply equally to versification. If I take the famous line which describes how the souls of the dead stood waiting by the river, imploring a passage from Charon:
Tendebantque manus ripae ulterioris amore,
and if I translate it, 'and were stretching forth their hands in longing for the further bank,' the charm of the original has fled. Why has it fled? Partly (but we have dealt with that) because I have substituted for five words, and those the words of Virgil, twelve words, and those my own. In some measure because I have turned into rhythmless prose a line of verse which, as mere sound, has unusual beauty. But much more because in doing so I have also changed the meaning of Virgil's line. What that meaning is I cannot say: Virgil has said it. But I can see this much, that the translation conveys a far less vivid picture of the outstretched hands and of their remaining outstretched, and a far less poignant sense of the distance of the shore and the longing of the souls. And it does so partly because this picture and this sense are conveyed not only by the obvious meaning of the words, but through the long-drawn sound of 'Tendebantque,' through the time occupied by the five syllables and therefore by the idea of 'ulterioris,' and through the identity of the long sound 'or' in the penultimate syllables of 'ulterioris amore'—all this, and much more, apprehended not in this analytical fashion, nor as added to the beauty of mere sound and to the obvious meaning, but in unity with them and so as expressive of the poetic meaning of the whole.
It is always so in fine poetry. The value of versification, when it is indissolubly fused with meaning, can hardly be exaggerated. The gift for feeling it, even more perhaps than the gift for feeling the value of diction, is the specific gift for poetry, as distinguished from other arts. But versification, taken, as far as possible, all by itself, has a very different worth. Some aesthetic worth it has; how much, you may experience by reading poetry in a language of which you do not understand a syllable. The pleasure is quite appreciable, but it is not great; nor in actual poetic experience do you meet with it, as such, at all. For it is not added to the pleasure of the meaning when you read poetry that you do understand: by some mystery the music is then the music of the meaning, and the two are one. However fond of versification you might be, you would tire very soon of reading verses in Chinese; and before long of reading Virgil and Dante if you were ignorant of their languages. But take the music as it is in the poem, and there is a marvellous change. Now
It gives a very echo to the seat
Where Love is throned;
or 'carries far into your heart,' almost like music itself, the sound
Of old, unhappy, far-off things
And battles long ago.
