Thomas Merton was a Cistercian monk and writer who was active in the American civil rights and peace movements of the 1960s.

Let no one hope to find in contemplation an escape from conflict, from anguish or from doubt. On the contrary, the deep, inexpressible certitude of the contempla­tive experience awakens a tragic anguish and opens many questions in the depths of the heart… Hence is it clear that genuine contemplation is incompatible with complacency and with smug acceptance of prejudiced opinions. It is not mere passive acquiescence in the status quo, as some would like to believe—for this would reduce it to the level of spiritual anesthesia. Contemplation is no pain-killer.
