Now the Constitution doesn’t say how this right is to be enforced, but it says it shall be done. And from 1793 to 1850 it depended upon the states ho… - Harry V. Jaffa

And what this could mean, as illustrated by what happened in 1854, the first real test of the Fugitive Slave Act? There was a slave named Anthony Burns in Virginia who stowed away on board a coastal vessel that then sailed to Boston. And Anthony Burns, who was apparently quite literate but not very smart, wrote a letter to his brother back in Virginia telling him where he was. Well, before Anthony Burns was returned to the State of Virginia, the President, Franklin Pierce, had sent an artillery regiment of marines to Boston. He had federalized the National Guard of Boston. He had 3,000 soldiers surrounding them, making sure that nobody could break the jail and let Anthony Burns out. This was an example of the way in which the federal police power would be used to make sure that slaves were returned to their masters or that slaves couldn’t escape from their masters. So this is the real issue.

In 1896, in Plessy v. Ferguson, the Court decided that 'separate but equal' did not violate the equal protection clause, and the South and not only the South relied upon this decision in building their systems of racially segregated public schools. The Court's 1896 decision can be explained in part by reason of the fact that the country—and the Western World generally—was then nearly submerged by the 'evolutionary' enlightenment. This movement, which dominated the intellectual elites in the universities, the law schools, and the media, denied the story of Creation in the Bible, and rejected the hitherto received idea that "God hath made of one blood all nations of men for to dwell on all the face of the earth." It entertained instead the idea that the races of mankind did not all emerge at the same time from the subhumanity which preceded their humanity. Evolutionary doctrine encouraged the idea that there was a fundamental inequality among the aforesaid races, and this idea virtually relegated to the "dustbin of history" the contrary idea, enshrined in the Declaration of Independence and the Gettysburg Address, "that all men are created equal."

The idea of liberty, or the liberty which is a blessing, being an emancipation of the passions from moral restraint had no place in the constitutional doctrine of the novus ordo seclorum. The liberty which is a blessing must be good for the one who possesses it. It must therefore be a good in the sight of God, who is the source of blessings. Such a good must point to felicity, whether in this world or the next, as its consummation. By calling the advantages of liberty "blessings," the Constitution, which in certain respects makes perhaps the most radical break in all human history with all that has gone before it, nonetheless, in its understanding of the connection between happiness and virtue, aligns itself decisively with traditional moral philosophy and moral theology.
