The arc of the moral universe T-Shirt

Quote Investigator: Theodore Parker was a Unitarian minister and prominent American Transcendentalist born in 1810 who called for the abolition of slavery. In 1857 a collection of “Ten Sermons of Religion” by Parker was published and the third sermon titled “Of Justice and the Conscience” included figurative language about the arc of the moral universe: Look at the facts of the world. You see a continual and progressive triumph of the right. I do not pretend to understand the moral universe, the arc is a long one, my eye reaches but little ways. I cannot calculate the curve and complete the figure by the experience of sight; I can divine it by conscience. But from what I see I am sure it bends towards justice. Things refuse to be mismanaged long. Jefferson trembled when he thought of slavery and remembered that God is just. Ere long all America will tremble. In 1918 a concise instance of the expression similar to the modern version was printed in a book titled “Readings from Great Authors” in a section listing statements attributed to Theodore Parker: The arc of the moral universe is long, but it bends towards justice.
