“One thing we knew for certain- despite all our certainties, it was very difficult to guess what one individual was thinking at any given moment.”

“Whether the British ruling class are wicked or merely stupid is one of the most difficult questions of our time, and at certain moments a very important question.”

“To explain all nature is too difficult a task for any one man or even for any one age. Tis much better to do a little with certainty & leave the rest for others that come after than to explain all things by conjecture without making sure of any thing.”

“What we can do, we must do: we must use what we are given, and we must use it the best we can, however much or little help we have for the task. What you have been given is a hard thing--a very hard thing... But my darling, what if there were no one who could do the difficult things?”

“it is clear that we must trust what is difficult; everything alive trusts in it, everything in Nature grows and defends itself any way it can and is spontaneously itself, tries to be itself at all costs and against all opposition. We know little, but that we must trust in what is difficult is a certainty that will never abandon us; it is good to be solitary, for solitude is difficult; that something is difficult must be one more reason for us to do it.”

“All things that we are given are not ours to keep, all we get is the moment.”
