The true division of humanity is this: the luminous and the dark.To diminish the number of the dark, to increase the number of the luminous, there is the aim.That is why we cry: education, knowledge! to learn to read is to kindle a fire; every syllable spelled sparkles.But whoever say light does not necessarily say joy.There is suffering in light; an excess burns. Flames is hostile to the wing. To burn and yet to fly, this is the miracle of genius
Victor Hugo, Les Misérables
