Who has said it?

�One impulse from a vernal wood May teach us more of man. Of moral evil and of good Than all the sages can.�

Wordsworth, a major Romantic poet, believed nature could teach moral and spiritual truths better than human sages. Options A, B, and C are all important writers but not the author of these lines.
