There's more of wisdom in it.

And hark! how blithe the throstle sings!
And he is no mean preacher;
Come forth into the light of things,
Let Nature be your teacher.

She has a world of ready wealth,
Our minds and hearts to bless--
Spontaneous wisdom breathed by health,
Truth breathed by chearfulness.

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

Sweet is the lore which nature brings;
Our meddling intellect
Mishapes the beauteous forms of things;
--We murder to dissect.

Enough of science and of art;
Close up these barren leaves;
Come forth, and bring with you a heart
That watches and receives.
