“Do not the Rays which differ in Refrangibility differ also in Flexibility; and are they not by their different inflexions separated from one another, so as after separation to make the Colours in the three Fringes…? And after what manner are they inflected to make those Fringes?”

“Do not several sorts of Rays make Vibrations of several bignesses, which according to their bigness excite Sensations of several Colours, much after the manner that the Vibrations of the Air, according to their several bignesses excite Sensations of several Sounds? And particularly do not the most refrangible Rays excite the shortest Vibrations for making a Sensation of deep violet, the least refrangible the largest form making a Sensation of deep red, and several intermediate sorts of Rays, Vibrations of several intermediate bignesses to make Sensations of several intemediate Colours?”

“Differences are not intended to separate, to alienate. We are different precisely in order to realize our need of one another.”

Desmond Tutu (1931) South African churchman, politician, archbishop, Nobel Prize winner

“Colour makes a difference. Gender makes a difference. Ethnicity makes a difference. Acting as if they don't will create more problems than it will solve.”

James Jones (1921–1977) American author

As quoted in Wisdom for the Soul : Five Millennia of Prescriptions for Spiritual Healing (2006) by Larry Chang

“Literature is not exhaustible, for the sufficient and simple reason that a single book is not. A book is not an isolated entity: it is a narration, an axis of innumerable narrations. One literature differs from another, either before or after it, not so much because of the text as for the manner in which it is read.”

Jorge Luis Borges book Other Inquisitions

"Note on (toward) Bernard Shaw"
Variant translation: A book is not an autonomous entity: it is a relation, an axis of innumerable relations. One literature differs from another, be it earlier or later, not because of the texts but because of the way they are read: if I could read any page from the present time — this one, for instance — as it will be read in the year 2000, I would know what the literature of the year 2000 would be like.
