Learn to read, speak out, resist: freedom is won, not granted.
For Douglass, learning to read and write made an enslaved person a judge of his own condition; the laws forbidding slaves to be taught showed that slaveholders knew they were dealing with human minds, not property.
Overhearing Hugh Auld forbid his wife to teach him, the boy understood that what his master most feared was the pathway from slavery to freedom.
Slavery depends on breaking the will; Douglass argues that a man without force lacks the essential dignity of humanity, and that resisting domination, even at great risk, restores self-respect.
After standing up to Edward Covey in 1834, Douglass wrote that however long he remained a slave in form, the day had passed forever when he could be a slave in fact.
Every human being has a natural right to liberty that no law or majority can cancel; after 1851 Douglass held that the Constitution, read by its text and Preamble, contained no guarantee of slavery and could be turned against it.
In the Fourth of July oration he calls the Constitution a glorious liberty document and accuses slaveholders of misreading it.
Rights are not handed down by the powerful but won through organized agitation, moral argument and, when necessary, resistance; those who want freedom without struggle want crops without ploughing.
In an 1857 speech on emancipation in the British West Indies he declared that power concedes nothing without a demand: it never did and it never will.
