What a deep faith in the rationality of the structure of the world and what a longing to understand even a small glimpse of the reason revealed in the world there must have been in Kepler and Newton to enable them to unravel the mechanism of the heavens in long years of lonely work!
That is part of the beauty of all literature. You discover that your longings are universal longings, that you're not lonely and isolated from anyone. You belong.

In Moscow you sit in a huge room at a restaurant; you know no one and no one knows you, and at the same time you don't feel a stranger. But here you know everyone and everyone knows you, and yet you are a stranger - a stranger... A stranger, and lonely...
There is no God, no universe, no human race, no earthly life, no heaven, no hell. It is all a dream, a grotesque and foolish dream. Nothing exists but you. And you are but a thought -a vagrant thought, a useless thought, a homeless thought, wandering forlorn among the empty eternities!
Feeling alone is what most likely sparked this way of thinking. Realizing that everyone (consciously or subconsciously) feels alone too - but no matter what, we're actually ALL together - is what has helped evolve my way of thinking about it. Life feels less lonely, and that's a big obstacle to overcome.
