 Suárez, against Vázquez (Vázquez 1608: I, 414, d. 73 c. 9 n. 43), held the second view. For him, the morality of the act consists in its dependence on volition as the productive impetus behind the act and on reason as the guiding set of rules that the agent takes herself to be guided by in shaping the precise characteristics of the act (De bonitate, sect. 2, n. 15). Suárez provides the parallel of the production of an artefact. An artefact can be evaluated by the standards applying to artefacts (say, beauty or ugliness), because its producer took herself to be guided, in the act of production, by the rules of her art (De bonitate, sect. 2, n. 17). The mode of production defines the nature of the object. Thus, two objects that look identical may be susceptible to different standards of judgment, because one might be an artefact (say, a carved stone) and the other not (say, a stone which fell from a cliff and broke, resulting in the same shape as the carved stone).
