ENThe Gaon was a religious thinker. But he was of great importance to the non-religious as well. I experience his greatness first in his powerful intellect, in his searching for scholarly truth, in his absolute dedication to his studies. No-one knows how geniuses appear. But their development does not happen in a vacuum. A genius needs a medium, an environment which understands his innovative ideas; otherwise the genius would remain simply an eccentric, one hardly remembered by later generations. Vilnius provided the medium. The Gaon grew up on the shoulders of his predecessors, great thinkers and Talmud experts. They remain in the shadows, and are often perhaps not appreciated enough. But they existed; and both the ones whose names are widely known, and the nameless ones, all embodied the nation's genius. Vilnius was a center of spirituality and Judaism; that is a well known fact. The name "Jerusalem of Lithuania" was well-earned. It is not known when this title appeared - there are many accounts. One legend says that in their seeking to defend their right to be represented in Lithuania's va'ad, the Jews of Vilnius found 333 experts who knew the Talmud by heart [p. 28].
