You might have ideas about ideas - when that light bulb in your brain starts glowing - about knowledge, illumination, creativity and enlightenment. What does Australia do with its ideas and inventions? What are our ideas about humour and levity? Or the 'unbearable lightness of being'? Do we collapse and stagger under the pressing weight of the world? Maybe you wanted to talk about the life sustaining sun or the destructive greenhouse. Perhaps the light most important to you is the light of the God and Heaven, the spirit or the Holy Ghost, or the metaphors of good and evil. Do you bask in the light of the computer or television screen?

What are your ideas about light? Here are some ideas about light from others.

No [person] has ever seen the Sun, or ever will. What we call 'sunlight' is only a narrow span of the entire solar spectrum - the immensely broad band of vibrations which the Sun, our nearest star, pours into space ... [The] radiance of the eternity is not white, it is infra-red

Arthur C. Clarke, The Light of Common Day, in John Carey (ed), The Faber Book of Science, 1995, Faber, London, p 427

The pursuit of perfection, then, is the pursuit of sweetness and light.

Matthew Arnold

The light on the hill is a figure of fable in Australian labour movement culture, but given its origins, I don't think it's stretching things to think of any and every social democratic government that achieves some small step to overcoming avoidable human misery and suffering as an instance of the light on the hill.

McKenzie Wark, Celebrities, Culture and Cyberspace: the light on the hill in a postmodern world, Pluto Press, Sydney, 1999, p 12

Light is the first of painters. There is no object so foul that intense light will not make beautiful.

Ralph Waldo Emerson

A lightning bolt is fire that has been compressed and hurled violently ... The constricted space of the compressed clouds forces out the air that is between them and by means of this pressure sets the air afire and hurls it the way a catapult does.

Seneca in 62AD

There are two kinds of light - the glow that illuminates and the glare that obscures.

James Thurber

Dante's journey through the celestial realm is not a trip to other physical 'worlds', as in modern science fiction, but to a kind of ecstatic cosmic dance through an increasingly abstract realm of light and motion. Here, luminescent choirs of angels fill the celestial space with heavenly harmonies - the mythical music of spheres ... [F]ollowing the Neoplatonic association of light with grace, bot the individual souls and the whole celestial environment become progressively more radiant. Light, as both fact and metaphore, is a distinguishing feature of the Paradiso.

Margaret Wertheim, The Pearly Gates of Cyberspace, p62 - 63
NB Wertheim is referring to Dante's medieval text, The Divine Comedy and the representations of space as Hell, Purgatory and Heaven

Laughter is the sun that drives winter from the human face.

Victor Hugo
