This Friday is Black Friday followed by the more exotic Cyber Monday. These are technical terms used in various branches of the retail trade. If Monday goes black, profit will be made. There might even be trumpets and jumping around, and that sense of "aren't we successful" which is so necessary to another year of pretty much doing exactly the same thing all over again.
Always have been moved to find a definition of "honest profit." I think probably the idea has been well researched, experiments conducted and so on, but an expectation of precision from language lost its charm sometime in the years preceding the second world war when Russell read Wittgenstein's Tractacus. Perhaps there is a hopeful amongst Occupy, busy again with definitions. Meanwhile the best I can do is "buy one get one free."
