Everything that Mr. Browning writes has claims upon the attention of those who study the philosophy of mind. There may be some difference of opinion as to Mr. Browning's position as a poet; it may be argued that, simply regarded as possessed of poetical faculty, he must be looked upon as inieriorto many other writers of poems in these fecund days; that much that he has written in rhyme would have been as readily communicable in prose; but there can be no difference of opinion as to Mr. Browning's exceptional mental vigour and calibre, nor can it be denied that very few men of equal capacity have either in this or in other ages devoted themselves to imaginative literature.
