Back then when slavery was a thing, there were abolitionists- to abolish is to end or stop- abolitionists for slavery would of helped slaves escape and they would of voted against slavery.
The that the Romantics NOT trying to escape from in the new industrial age is : Logic and Science
the romanticism movement believe in integration between an individual and Gods so they escape the advancement of industrial age to Religion, Mysticism , and Drugs (back then, narcotics were not as illegal as it is today)
hope this helps
