What was the Transcendentalists' general attitude toward problems in society, such as slavery?

Transcendentalism was a philosophical movement that held its ground in America for a good half a century. As the believers of this movement were against organised religion and believed that knowledge can be gained with the power of contemplating about the spirit and soul. The transcendentalists were against all kinds of social evils and unjust attitudes that prevailed in the American society at that time. Similarly the problem of slavery and woman emancipation for example greatly irked them. Because transcendentalism found its place only in literature and became a literary movement, the followers of this movement could not really solve the problems but they did voice them in their work, hoping it will open people's eyes.
