The Good how can we trust?

The good how can we trust?
Only the wise are just.
The good we use,
The wise we cannot choose.
These there are none above;
The good they know & love,
But are not known again
By those of lesser ken. —
They do not charm us with their eyes,
But they transfix with their advice.
No partial sympathy they feel,
With private woe or private weal,
But with the Universe joy & sigh,
Whose knowledge is their sympathy.
