I also post a quote of the day on most pages of my website and this is the one I noticed for today:
In every great time there is some one idea at work which is more powerful than any other, and which shapes the events of the time and determines their ultimate issues.And it set me to thinking. What is that one idea at work today that is more powerful than any other? And wouldn't that make a great topic for a Knowledge Cafe. I must do it!
But this is the joy for me. Francis Bacon has provoked me to think about this but he has been dead almost 400 years! Another man that hugely inspires me is Henry David Thoreau but that's another story.
