Laziness
Laziness, as distinct from the capital vice of sloth, is a generic name given to a number of sins or circumstances of sin, and hence it will be treated in several places.
(a) Thus, negligence is a want of prompt decision about duties to be performed. It is opposed to the virtue of diligence or solicitude, which pertains to prudence. Hence, negligence will be considered among the sins against prudence.
(b) Sluggishness (pigritia) is a tardy performance of duty, and will be considered among the sins opposed to diligence.
(c) Carelessness (torpor) is a perfunctory discharge of duties, without thought or love. It is one of the consequences of sloth given above (see 1324), and hence it is a sin against charity.
(d) Indolence is an excessive dislike of labor or exertion, caused by an inordinate love of recreation or bodily rest. It will be considered when we treat the sin of softness or delicacy, which is opposed to fortitude.
(e) Idleness is the actual omission of one’s duty on account of indolence, and hence it is considered among the sins against the various precepts. Thus, under the precepts of charity and of justice will be discussed the omission of labor to which one is bound.
