THE LIGHT INSIDE - 1999 , James Turrell, Museum of Fine Arts HoustonFrom an essay of Proust in Against Sainte-Beuve....
"The beautiful things we shall write if we have talent are inside us, indistinct, like the memory of a melody which delights us though we are unable to recapture its outline. Those who are obsessed by this blurred memory of truths they have never known are the men who are gifted...Talent is like a sort of memory which will enable them finally to bring this indistinct music closer to them, to hear it clearly, to note it down...."
In V. S. Niapaul's Nobel Lecture, he states that it is luck and much labor more than talent!
