“For anything that is hammered by a blow, day after day
However softly struck, at length is conquered and gives way.
Haven’t you seen how drops of water falling on their own
Have the power, over time, to wear their way through stone?”
– Lucretius, On the Nature of Things, 50BC
This is quite fundamental for life and the importance of persistance, individually and for society. Many small changes together, over time, create large, important ones. And in this lies hope, but also great danger.
