More quotes by Leo Tolstoy, Anna Karenina

"Without knowledge of what I am and why I am here, it is impossible to live, and since I cannot know that, I cannot live either. In an infinity of time, in an infinity of matter, and an infinity of space a bubble-organism emerges while will exist for a little time and then burst, and that bubble am I."
"They've got no idea what happiness is, they don't know that without this love there is no happiness or unhappiness for us--there is no life."
"Love those you hate you."
"Respect was invented to cover the empty place where love should be."
"I think... if it is true that there are as many minds as there are heads, then there are as many kinds of love as there are hearts."
