Resistance was often more subtle than revolts, escapes and sabotage. It involved, for example, the clandestine acquisition of reading and writing skills and the imparting of this knowledge to others.
— Women, Race & Class by Angela Y. Davis (Page 22)
This makes sense to me and it's a fascinating thing to think about because I assumed most resistance was used for revolts and attacks. I mean, how can you not want to kill your master? But it makes sense that in order for liberation to be achieved, one must learn and educate others with that knowledge. Slaves would learn to read and write and pass it on to others.
