A fool sees not the same tree that a wise man sees.
He whose face gives no light, shall never become a star.

Context

“The road of excess leads to the palace of wisdom. Prudence is a rich ugly old maid courted by Incapacity. He who desires but acts not, breeds pestilence. The cut worm forgives the plow. Dip him in the river who loves water. A fool sees not the same tree that a wise man sees. He whose face gives no light, shall never become a star. Eternity is in love with the productions of time. The busy bee has no time for sorrow. The hours of folly are measur'd by the clock, but of wisdom: no clock can measure. All wholsom food is caught without a net or a trap.” source
