Take this passage from _James Lee's Wife_: Oh, good gigantic smile o' the brown old earth, This autumn morning! How he sets his bones To bask i' the sun, and thrusts out knees and feet For the ripple to run over in its mirth; Listening the while, where on the heap of stones The white breast of the sea-lark twitters sweet.
The smile, the mirth, the listening, might be said to impute humanity to Nature: but the Earth and the Sea are plainly quite distinct from us.
These are great giant creatures who are not ourselves: Titans who live with one another and not with us; and the terms of our humanity are used to make us aware of their separate existence from us, not of their being images only of our mind.
Another passage will illustrate the same habit of Browning's mind with nature.

He describes, for the purpose of his general thought, in _Fifine at the Fair_, the course of a stormy sunset.

The clouds, the sun, the night, act like men, and are written of in terms of humanity.

But this is only to explain matters to us; the mighty creatures themselves have nothing to do with us.

They live their own vast, indifferent life; and we see, like spectators, what they are doing, and do not understand what we see.
