I want to know the answer to the following question:
In what work did Ferguson explain how humans advanced from a hunting and gathering society to a commercial and civil society without "signing" a social contract?
All the background I'm provided with is that "Hume's essay Of the Original Contract argues that governments derived from consent are rarely seen, and civil government is grounded in a ruler's habitual authority and force.". Is that enough to answer the question?
Answer: no
