Our entire much-praised technological progress, and civilization generally, could be compared to an axe in the hand of a pathological criminal.
In my case Pilgrim’s Progress consisted in my having to climb down a thousand ladders until I could reach out my hand to the little clod of earth that I am.
Forward, forward let us range, let the great world spin for ever down the ringing grooves of change.
Believing in progress does not mean believing that progress has yet been made. That is not the sort of belief that indicates real faith.
