Even when I'm not really listening to Michel Onfray's rapid fire lectures, when I'm daydreaming or looking at the scenery, I always pick up on the etymologies that pepper them. Aug. 15 was a question/answer session and when one of the students asked about Adam Smeess and the influence of the invisible hand, Onfray entered into somewhat of a diatribe against the notion that the free market would lead to general wealth. He pointed out that the word "economy" comes from the Greek word meaning "household management." So I learned, at least, that my "home economics" class in 7th grade was based on a redundancy, at least in terms of etymology.
