The greater number of them are beautiful, and they would gain rather than lose if they were published separately from the poems.
Some are plainly of the same date as the poems.

Others, I think, were written in Browning's early time, and the preceding poems are made to fit them.

But whatever be their origin, they nearly all treat of love, and one of them with a crude claim on the love of the senses alone, as if that--as if the love of the body, even alone--were not apart from the consideration of a poet who wished to treat of the whole of human nature.

Browning, when he wished to make a thought or a fact quite plain, frequently stated it without any of its modifications, trusting to his readers not to mistake him; knowing indeed, that if they cared to find the other side--in this case the love which issues from the senses and the spirit together, or from the spirit alone--they would find it stated just as soundly and clearly.

He meant us to combine both statements, and he has done so himself with regard to love.
When, however, we have considered these exceptions, it still remains curious how little the passionate Love-poem, with its strong personal touch, exists in Browning's poetry.
