The frenzy of our activism neutralizes our work for peace. It destroys our own inner capacity for peace. It destroys the fruitfulness of our own work, because it kills the root of inner wisdom which makes work fruitful.

Thomas Merton (1915–1968) was an American Roman Catholic Trappist monk, poet, author, theologian, student of interfaith understanding, and activist for social change. His work dove deep into the ways in which religions are similar, and he envisioned a more peaceful world through helping people understand and appreciate spiritual paths different from their own. He wrote over fifty books and countless essays on social justice, religion, and theology throughout his life, and he strove to weave mysticism into his works while connecting these beliefs to overarching societal ideas and structures.
