In action, yet may make amends in praise.
Fabricius, Cesalpinus, say your word,
Not yours, or mine, but Truth's, as you receive it!
You miss a point I saw? See others, then!
Misread my meaning? Yet expound your own!
Obscure one space I cleared? The sky is wide,
And you may yet uncover other stars.
For thus I read the meaning of this end:
There are two ways of spreading light: to be
The candle or the mirror that reflects it.
I let my wick burn out--there yet remains
To spread an answering surface to the flame
That others kindle.

Turn me in my bed.
The window darkens as the hours swing round;
But yonder, look, the other casement glows!
Let me face westward as my sun goes down.
