Fyodor Dostoyevsky said this quote
“ If I did not believe in life, if I were to lose faith in the woman I love, if I were to lose faith in the order of things, even if I were to become convinced, on the contrary, that everything is a disorderly, damned, and perhaps devilish chaos, if I were struck even by all the horrors of human disillusionment-still I would want to live, and as long as I have bent to this cup, I will not tear myself from it until I've drunk it all! ”
