Famous quotes containing the word nature:
“God is a being of transcendent and unlimited perfections: his nature therefore is incomprehensible to finite spirits.”
—George Berkeley (1685–1753)
“For many are the trees of God that grow
In Paradise, and various, yet unknown
To us; in such abundance lies our choice
As leaves a greater store of fruit untouched,
Still hanging incorruptible, till men
Grow up to their provision, and more hands
Help to disburden Nature of her bearth.””
—John Milton (1608–1674)
