"One has a nose, the nose scents and it chooses, an artist is simply a kind of pig snouting truffles." Igor Stravinsky (1882-1971)

"I have become convinced that of all that human language has produced truly and simply beautiful, I knew nothing before I learned Greek.... Without a knowledge of Greek there is no education."
"I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives."
Lev Nikolaevich (1828–1910)
