" 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
