Famous quotes containing the words proof and/or system:

“Ah! I have penetrated to those meadows on the morning of many a first spring day, jumping from hummock to hummock, from willow root to willow root, when the wild river valley and the woods were bathed in so pure and bright a light as would have waked the dead, if they had been slumbering in their graves, as some suppose. There needs no stronger proof of immortality. All things must live in such a light. O Death, where was thy sting? O Grave, where was thy victory, then?”
—Henry David Thoreau (1817–1862)

“Never expect any recognition here—the system prohibits it. The cross is not affixed to the genius, no, the genius is affixed to the cross.”
—Franz Grillparzer (1791–1872)
