English mystery and detective writer (1890–1976)
- "I don't think necessity is the mother of invention -- invention, in my opinion, arises directly from idleness, possibly also from laziness. To save oneself trouble."
- Simple: I don't think it's need that makes people think of new things. I think people think of new ways of doing things only because they are lazy and don't want to work hard. To save themselves from having to do work.
- What it means: New ideas come from being lazy when it comes to doing something and wanting to do it in an easier way because of it.
