He belonged to a certain type of English society, and he rarely got out of it in his poetry.

He inhabited a certain Park of morals, and he had no sympathy with any self-ethical life beyond its palings.

What had been, what was proper and recognised, somewhat enslaved in Tennyson that distinctiveness and freedom of personality which is of so much importance in poetry, and which, had it had more liberty in Tennyson, would have made him a still greater poet than he was.
Browning, on the other hand--much more a person in society than Tennyson, much more a man of the world, and obeying in society its social conventions more than Tennyson--never allowed this to touch his poems.

As the artist, he was quite free from the opinions, maxims, and class conventions of the past or the present.

His poetry belongs to no special type of society, to no special nationality, to no separate creed or church, to no settled standard of social morality.
