“Go on philosophers--teach, enlighten, kindle, think aloud, speak up, run joyfully toward broad daylight, fraternize in the public squares, announce the glad tidings, lavish your alphabets, proclaim human rights, sing your Marseillaises, sow enthusiasms, tear off green branches from the oak trees. Make thought a whirlwind. This multitude can be sublimated. Let us learn to avail ourselves of this vast conflagration of principles and virtues, which occasionally sparkles, bursts, and shudders. These bare feet, these naked arms, these rags, these shades of ignorance, depths of despair, the gloom can be used for the conquest of the ideal. Look through the medium of the people, and you will discern the truth. This lowly sand that you trample underfoot, if you throw it into a furnace and let it melt and seethe, will become sparkling crystal; and thanks to such as this a Galileo and a Newton will discover the stars.”
