John A. Campbell, Dred Scott v. Sandford — Concurring Opinion (1857)
“ It is so odious that nothing can be suffered to support it but positive law.That there is a difference in the systems of States which recognise and which do not recognise the institution of slavery cannot be disguised. Constitutional law, punitive law, police, domestic economy, industrial pursuits, and amusements, the modes of thinking and of belief of the population of the respective communities all show the profound influence exerted upon society by this single arrangement. This influence was discovered in the Federal Convention, in the deliberations on the plan of the Constitution. ”
