There is this strongly conservative tendency in human nature: we do not like to move one step forward. I think of mankind just as I read ...of persons who become frozen in snow; all such, they say, want to go to sleep, and if you try to drag them up, they say, "Let me sleep; it is so beautiful to sleep in the snow", and they die there in that sleep. So is our nature. That is what we are doing all our life, getting frozen from the feet upwards, and yet wanting to sleep.
