   • 宗教裡的苦難既是現實的苦難的表現，又是對這種現實的苦難的抗議。宗教是被壓迫生靈的嘆息，是無情世界的感情，正像它是沒有精神的制度的精神一樣。宗教是人民的鴉片。 [MSC, trad.]

     Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.
