So the next person on my list of people who have contributed to society…is none other than……John Brown. Mr. Brown lived at a time when people talked, and talked, and talked, and after talking, talked some more about the abolition of slavery. Mr. Brown took action and put his money where his mouth is…and unknowingly sparked the start of the civil war which eventually led to the slaves being free. Mr. Brown’s contribution to society is that all the millions and millions of free slaves now…owe their freedom to men like John Brown…who stood up for the truth in spite of the social pressure to be otherwise….he is understood by some to be a madmen yes, but the only way the south was going to give up the slaves was by force…as slavery had become a lifestyle and one of the major economic factors for wealthy slave owners…..no pay….free labor……hell yeah…sounds like a deal…….so thank you Mr. Brown….for your contribution to society.
