16. That is, one kind of perverted person is he who commits evil but knows and understands that he is committing evil. Such a person can be reformed by counsel and advice, and sometimes his own conscience also pricks and brings him to the right path, for his habits only are perverted, not his mind. But there is another kind of a person whose mentality has been perverted, who has lost the discrimination between good and evil, for whom the life of sin has become alluring and lustrous, who abhors good and takes evil for civilization and culture, who regards goodness and piety as things of the past, and sinfulness and wickedness as progressiveness, and for whom guidance becomes error and error becomes guidance. Such a person is not amenable to any advice and any admonition. He neither takes warning from his own follies nor listens to a well wisher. It is useless to waste ones time and energy for the reformation of such a person. Instead, the inviter to the truth should turn his attention towards those whose consciences may still be alive and who may still be inclined to listen to the truth.
