Update: If you cannot find or invent a pithy saying about simplicity (or even if you can), how about bringing a small physical object that, for you, embodies simplicity? A saying is something we can share by being able to repeat it and understand it, but an object is something we can share by holding it, interacting with it, letting it be our focus.
"Give me the simple life." – Harry Ruby lyric
"Simplicity is about subtracting the obvious, and adding the meaningful." – John Maeda
"I ask many questions, and when the answer is simple, then God is answering." – Albert Einstein (among many quotes of his that pertain to simplicity)
"One should use common words to say uncommon things" – Arthur Schopenhauer
"Simplicity...relates to the burden which a thing puts on someone trying to explain or understand it." – Wikipedia
After investigating creativity, which makes things appear where there were none before, now we turn to simplicity, which makes things disappear;-) Like creativity, simplicity is viewed as a good thing: "Simplicity" is the brand name of many a household appliance. But then, it's not a compliment to be called "simple-minded." Or is it?
This member-suggested theme seems like a wonderful fit for the group because it is an abstraction that everybody "gets," plus it has moral overtones, as well as importance in science (think of Occam's Razor). Also, winter seems to be a time of focusing on the essence of things. More relevant, perhaps, is that this group's exclusive focus on oral communication really stresses economy of expression.
The quotes above show much can be alluded to in a short sentence–each of the five suggests to me a completely different line of thinking. So I am requesting that each attendee bring a quote of their own, or even a "quotable" saying of their own, to the meeting. We will use these quotes as starting points, instead of topic questions, so bear that in mind when making your selection. Write it on a 3x5 card, or you can copy onto a card I'll provide.
That's pretty simple, isn't it?
