It has logic and emotion, but mostly logic. His logic is very clear that if you follow the bible you shouldn't condemned slavery and killings of hundred of people. When practicing the bible and being christians one has to act like christ and follow the teachings of him and the bible. They cannot prove Joseph's enslavement as wrong, but still enslave people who were like Joseph. In it Sewall not only condemns the practice of human trafficking, but goes on to challenge many common slave owners held the practice of enslavement and yet still be followers of God. He uses Joseph as example to bring light to what they are doing wrong. Sewall also cites several Biblical passages which Sewall uses to make a of the practice of man stealing. Using logic is very clear in his writing about people just choosing to ignore themselves on being a hypocrite and make them question their own strong held belief.
In "The Selling of Joseph: A Memorial," Samuel Sewall wants to criticize the institution of slavery, and prove that it does not conform to Christian ideals. He argues that Christians often read the Bible and condemn how Joseph was treated and sold by his brothers. However, they fail to see that if they do so, they must also believe that slavery is morally wrong. He thinks it is hypocritical to condemn the actions of the brothers, yet defend the institution of slavery. Therefore, he makes a logical argument about the necessary opposition of Christianity and slavery.
