"I admit, Mr. Bradshaw, it's a very dangerous thing to get up steam, if you don't intend to let the boat go. But when the steam is high enough, let her go, say I."
"Yes, but, Miss Anne, other people don't want to say so. The fact is, we are not all of us ready to let the boat go. It's got all our property in it-- all we have to live on." (Stowe 316)
Yet another one of those great quotes that just begs to be made too much of. Dred is littered with maritime references. Slavery is akin to piracy, Clayton lacks ballast, etc. More on this stuff later.
Stowe seems to be exploring white complicity in abolition in a similar vein that she critiqued white complicity in slave-holding in Uncle Tom's Cabin. In the same way that "good" slave-holding households were ultimately no different from the Simon Legree's of the South, those who bend or ignore the law in teaching slaves to read are ultimately participating in the same kind opposition to slavery as Vesey and Turner. In both texts the law is the problem . It's a tricky tactic and one that I don't think is completely successful, but in creating Clayton a lawyer is who is bound by law to practice against his conscience Stowe reveals the way white southern moderates are also bound and potentially subject to the same laws as slaves.
Thinking about the way this book both evokes violence and suppresses it makes me how much of John Brown's ghost is haunting the text balong side the black insurrectionists. This presents an interesting point of attack regarding black and white doppelgangers in the texts I'm looking at. I mentioned earlier that Dred was an easy stand-in for black insurrectionists but he can also be a handy decoy from John Brown who was very much at large at the time of Dred's publication. One might be able to argue that at the same time that Stowe invokes the possibility for white insurrection she still makes Dred the scapegoat for anti-slavery violence.
Edited to add: John Brown invoke on page 499 of the Levine edition:
How stinging is it at such a moment to view the whole respectability of civilized society upholding and glorifying the murderer; calling his sin by soft names, and using for his defence every artifice of legal injustice! Some in our own nation have had bitter occasion to know this, for we have begun to drink the cup of trembling which for so many ages has been drank alone by the slave. Let the associates of Brown ask themselves if they cannot understand the midnight anguish of Harry!
