Some souls, because of their negligence or spiritual sloth, do not pass from the age of beginners to that of proficients. These are retarded souls; in the spiritual life they are like abnormal children, who do not happily pass through the crisis of adolescence and who, though they do not remain children, never reach the full development of maturity. Thus these retarded souls belong neither among beginners nor among proficients. Unfortunately they are numerous.

Th soul falls into tepidity, which, with habitual negligence, is affection for venial sin or the disposition of the will to commit certain venial sins deliberately when the occasion presents itself. There is finally, as it were, the firm resolution to remain in this state. In addition to the lack of the spirit of sacrifice, other causes may produce this tepidity of retarded souls: namely, levity of spirit, the thoughtlessness with which one tells, for example, officious lies (i.e., lies of expediency) whenever the occasion offers; spiritual sloth, which leads finally to the abandonment of the spiritual war against our defects, against our predominant fault, which quite frequently tries to pass for a virtue, and gives rise in us to other more or less inordinate passions. 

A person thus arrives at carelessness and indifference in regard to perfection and no longer truly tends toward it. The fact that he has perhaps promised to tend toward it by the way of the counsels is forgotten, as is also the loftiness of the supreme precept: “Thou shalt love the Lord thy God with thy whole heart and with thy whole soul and with all thy strength and with all thy mind.”
