d or evil mind, of which it is rash to form a judgment."
Therefore some actions are indifferent according to their species.

_I answer that,_ As stated above (AA. 2, 5), every action takes its
species from its object; while human action, which is called moral,
takes its species from the object, in relation to the principle of
human actions, which is the reason. Wherefore if the object of an
action includes something in accord with the order of reason, it will
be a good action according to its species; for instance, to give alms
to a person in want. On the other hand, if it includes something
repugnant to the order of reason, it will be an evil act according to
its species; for instance, to steal, which is to appropriate what
belongs to another. But it may happen that the object of an action
does not include something pertaining to the order of reason; for
instance, to pick up a straw from the ground, to walk in the fields,
and the like: and such actions are indifferent according to their
species.

Reply Obj. 1: Privation is twofold. One is privation "as a result"
(_privatum esse_), and this leaves nothing, but takes all away: thus
blindness takes away sight altogether; darkness, light; and death,
life. Between this privation and the contrary habit, there can be no
medium in respect of the proper subject. The other is privation "in
process" (_privari_): thus sickness is privation of health; not that it
takes health away altogether, but that it is a kind of road to the
entire loss of health, occasioned by death. And since this sort of
privation leaves something, it is not always the immediate contrary
of the opposite habit. In this way evil is a privation of good, as
Simplicius says in his commentary on the Categories: because it does
not take away all good, but leaves some. Consequently there can be
something between good and evil.

Reply Obj. 2: Every object or end has some goodness or malice, at
least natural to it: but this does not imply moral goodness or
malice, which is considered in relation to the reason, as stated
above. And it is of this that we are here treating.

Reply Obj. 3: Not everything belonging to an action belongs also to
its species. Wherefore although an action's specific nature may not
contain all that belongs to the full complement of its goodness, it
is not therefore an action specifically bad; nor is it specifically
good. Thus a man in regard to his species is neither virtuous nor
wicked.
