Lovitt: Das, was ein anderes verschuldet

Das, was ein anderes verschuldet is a quite idomatic expression that here would mean to many German readers "that which is the cause of something else." The verb verschulden   actually has a wide range of meanings-to be indebted, to owe, to be guilty, to be responsible for or to, to cause. Heidegger intends to awaken all these meanings and to have connotations of mutual interdependence sound throughout this passage. (QCT   p. 7)
