Consideration of the range of definitions illuminates the difficulty in producing an account that
satisfies all of them.
To take some of the more common examples, definitions of liberum
arbitrium included: i) the faculty of will and reason by which good is chosen with the help of
grace, but evil when grace is absent;
ii) the ability to preserve uprightness of will for its own
sake;
iii) the privation or absence of coercion (often also called freedom from necessity);
iv)
the flexibility toward opposite acts;
v) the flexibility toward good and evil;
vi) the power of
being the cause of one’s own action;
vii) the power of doing what one wishes;
viii) not being
subordinate or “under another”
; and ix) to be master of one’s own acts.
There are obvious
prima facie tensions between several of these definitions, particularly when mapped onto
considerations about intellectual natures in their various states. Anselm’s definition, the ability to
preserve uprightness of will for its own sake, appears to be incompatible with flexibility toward
good and evil acts, and seems to suggest that flexibility to opposite acts does not belong to the
that do not also consider the underlying causes of liberum arbitrium. Jamie Anne Spiering, “An Innovative
Approach to Liberum Arbitrium in the Thirteenth Century: Philip the Chancellor, Albert the Great, and Thomas
Aquinas” (PhD diss., The Catholic University of America, 2010), 81–7.

to Augustine within the thirteenth century discussions. Briefly tracing the history of the definition, Bougerol writes,
