Searching instances of the word “simplify” in Watchtower literature, I stumbled across this.
The Asiatic mind finds it difficult to accept new ways, to simplify and to make advantageous changes. They fear conversion and dislike others’ offering them help. Many continually live in a realm of unreality and refuse to face modern facts of life. The abounding of idolatry, ancestor worship and immorality (practically no moral restraints exist, through having no conception of sin) has brought the mentality of the Asiatic very low; so low, in fact, that many lead an existence not far from that of animals. To such a degree of debasement has the Devil driven these masses. Nevertheless, Jehovah has some of honest and contrite heart in these lands who are being hunted out by His witnesses. w56 1/15 p. 40
