ry,_ The Philosopher says (Ethic. iii, 7; iv, 1) that
"every vice sins by doing more than one ought, and when one ought
not"; and in like manner as to the other circumstances. Therefore the
species of sins are not diversified in this respect.

_I answer that,_ As stated above (A. 8), wherever there is a special
motive for sinning, there is a different species of sin, because the
motive for sinning is the end and object of sin. Now it happens
sometimes that although different circumstances are corrupted, there
is but one motive: thus the illiberal man, for the same motive, takes
when he ought not, where he ought not, and more than he ought, and so
on with the circumstances, since he does this through an inordinate
desire of hoarding money: and in such cases the corruption of
different circumstances does not diversify the species of sins, but
belongs to one and the same species.

Sometimes, however, the corruption of different circumstances arises
from different motives: for instance that a man eat hastily, may be
due to the fact that he cannot brook the delay in taking food, on
account of a rapid exhaustion of the digestive humors; and that he
desire too much food, may be due to a naturally strong digestion;
that he desire choice meats, is due to his desire for pleasure in
taking food. Hence in such matters, the corruption of different
circumstances entails different species of sins.

Reply Obj. 1: Evil, as such, is a privation, and so it has different
species in respect of the thing which the subject is deprived, even
as other privations. But sin does not take its species from the
privation or aversion, as stated above (A. 1), but from turning to
the object of the act.

Reply Obj. 2: A circumstance never transfers an act from one species
to another, save when there is another motive.

Reply Obj. 3: In the various species of gluttony there are various
motives, as stated.

QUESTION 73

OF THE COMPARISON OF ONE SIN WITH ANOTHER
(In Ten Articles)

We must now consider the comparison of one sin with another: under
which head there are ten points of inquiry:

(1) Whether all sins and vices are connected with one another?

(2) Whether all are equal?

(3) Whether the gravity of sin depends on its object?

(4) Whether it depends on the excellence of the virtue to which it is
opposed?

(5) Whether carnal sins are more grievous than spiritual sins?

(6) Whether the gravity of sins depen
