My mother is a big fan of precision, and tries her best to maintain it. Unfortunately, her own incompetence gets in the way. Dinner is served, except when a can won't open. That's the way she is: fine unless something goes wrong and that minor obstacle becomes a huge wall she can't scale. She becomes helpless whenever things don't go smoothly, or exactly as she imagined them.
The greatest element in life is not what occupies most of its time, else sleep would stand high in the scale. Nor is it what engrosses most of its thought, else money would be very high. The two or three hours of worship and preaching weekly has perhaps been the greatest signal influence on English life. Half an hour of prayer, morning or evening, every day, may be a greater element in shaping our course than all our conduct and all our thought.
The main issue [of the Scientific Revolution] is that the people in the industrialised countries are getting richer, and those in the non-industrialised countries are at best standing still: so the gap between the industrialised countries and the rest is widening every day. On the world scale this is the gap between the rich and the poor.
