meaning of practice that he has in mind: a practice, then, is any act that is
within our power. By this he means a voluntary act which proceeds from
a dictate of reason, but not necessarily according to right reason. The added
condition of an operation voluntarily chosen in accordance with right reason
is part of the fourth and strictest denition of practice. Mair, however, believ-
ing himself to be following the common opinion, insists that this is too strict
because even malicious actions, when done voluntarily or guided by erroneous
reason, should be counted as practices by denition.
This denition can be ne-tuned even further. Every act of the will, Mair
points out, is a practice in the sense of, rst, an elicited act of the will (actus
elicitus) and, subsequently, an act commanded by the will (actus imperatus).
Thus, the commanded act of the will translates into an act executed by another
power. Among scholastic thinkers, there is some debate about whether or not
an intellectual act can be considered a practice. Scotus, for one, insists that
speculation, which is an act of the intellect, is a practice only in a loose sense
(extendendo nomen). In this loose sense, the intellect is said to “extend” itself
to the activity of speculation. Strictly speaking, however, no intellectual act is
a practice, and it is this strict sense of “extension” which is meant when we say

super primum et secundum Sententiarum, vol. 1, ed. A.D. Trapp and Venicio Marcolino

See Mair, In Sent. (1519), prol., qu. 6, fol. 14rb: “Tertio capitur pro operatione quae est in
potestate operantis. Ista acceptio est illa de qua communiter auctores loquuntur.” Mair
shows his preference for this denition in his rst proposition: “prima est: omnis actus
voluntatis est praxis patet, quia est actus existens in potestate operantis, ergo est praxis;
per eius dinitionem, primo actus elicitus, postea actus imperatus ab eo.”
See Mair, In Sent. (1519), prol., qu. 6, fol. 14rb: “Quarto modo accipitur pro omni opera-
tione conformiter elicita dictamine rectae rationis.”
Scotus was read by later readers as holding that this fourth and strictest denition was the
most proper denition of a practice. (See, for instance, Gregory of Rimini, Lectura, vol. 1,
liber , prol., qu. 5, art. 1, p. 152.) Scotus’s view is understandable, since a practice guided
by reason requires practical knowledge, and yet it hardly makes sense to call something
knowledge if it leads us to make bad decisions. For Scotus’s inuential denition of a
practice, see Ordinatio, vol. 1, ed. C. Balić (Vatican City, 1954), liber , prol., pars 5, qu. 1–2,
no. 228, p. 155. It is the third and last condition in this denition that Rimini understood
to commit Scotus to the fourth and strictest denition of a practice.
See Mair, In Sent. (1519), prol., qu. 6, fol. 14rb: “Ex his sequuntur aliquae propositiones.
Prima est omnis actus voluntatis est praxis patet, quia est actus existens in potestate ope-
rantis, ergo est praxis, per eius dinitionem, primo actus elicitus, postea actus imperatus
ab eo.”
