FOURTH ARTICLE [II-II, Q. 168, Art. 4]

Whether There Is a Sin in Lack of Mirth?

Objection 1: It would seem that there is no sin in lack of mirth. For
no sin is prescribed to a penitent. But Augustine speaking of a
penitent says (De Vera et Falsa Poenit. 15) [*Spurious]: "Let him
refrain from games and the sights of the world, if he wishes to
obtain the grace of a full pardon." Therefore there is no sin in lack
of mirth.

Obj. 2: Further, no sin is included in the praise given to holy men.
But some persons are praised for having refrained from mirth; for it
is written (Jer. 15:17): "I sat not in the assembly of jesters," and
(Tobias 3:17): "Never have I joined myself with them that play;
neither have I made myself partaker with them that walk in
lightness." Therefore there can be no sin in the lack of mirth.

Obj. 3: Further, Andronicus counts austerity to be one of the
virtues, and he describes it as a habit whereby a man neither gives
nor receives the pleasures of conversation. Now this pertains to the
lack of mirth. Therefore the lack of mirth is virtuous rather than
sinful.

_On the contrary,_ The Philosopher (Ethic. ii, 7; iv, 8) reckons the
lack of mirth to be a vice.

_I answer that,_ In human affairs whatever is against reason is a
sin. Now it is against reason for a man to be burdensome to others,
by offering no pleasure to others, and by hindering their enjoyment.
Wherefore Seneca [*Martin of Braga, Formula Vitae Honestae: cap. De
Continentia] says (De Quat. Virt., cap. De Continentia): "Let your
conduct be guided by wisdom so that no one will think you rude, or
despise you as a cad." Now a man who is without mirth, not only is
lacking in playful speech, but is also burdensome to others, since he
is deaf to the moderate mirth of others. Consequently they are
vicious, and are said to be boorish or rude, as the Philosopher
states (Ethic. iv, 8).

Since, however, mirth is useful for the sake of the rest and
pleasures it affords; and since, in human life, pleasure and rest are
not in quest for their own sake, but for the sake of operation, as
stated in _Ethic._ x, 6, it follows that "lack of mirth is less
sinful than excess thereof." Hence the Philosopher says (Ethic. ix,
10): "We should make few friends for the sake of pleasure, since but
little sweetness suffices to season l
