[Eisenstein]

If you can't come up with a scenario where a slave would improve their life by innovating the tools and objects they had available to them, or a scenario in which a master is not a one dimensional caricature, or a scenario where a slave is not a stupid pack animal that can only follow orders, then the burden is not on history to convince you otherwise.

[WalterBright]

History shows us that free men produce far more innovations than unfree ones.

[Eisenstein]

* History is not written by unfree peoples

* You have not taken into account factors such as portions of population, different types of slavery or really anything at all

* Your original logic has been shown to be inherently flawed and you are still trying to argue by using evidence that turns out to be an assumption when examined
