"Business is the salt of life."
Voltaire (1694 - 1778)
Voltaire was a civil libertarian. He was in favor of freedom and advocated things like freedom of religion, freedom of personal expression, international free trade and, of all things, state politics free from the politics of the church!
What? Separation of church and state? And individual freedoms?
So what did he mean when he said business? Busy ness? Yes, in a way.
What is business? When I studied economics in college I, smartly, had a business and economics dictionary! Here is a good definition of business:
"An economic system in which goods and services are exchanged for one another or money, on the basis of their perceived worth. Every business requires some form of investment and a sufficient number of customers to whom its output can be sold at profit on a consistent basis." (This is from businessdictionary.com)
