An increasing number of studies indicate that virtues affect brain structure. These studies might shed new light on some neuroethical perspectives suggesting that our brain network activity determines the acquisition and permanence of virtues. According to these perspectives, virtuous behavior could be interpreted as the product of a brain mechanism supervised by genes and environment and not as the result of free choice. In this respect, the neural correlates of virtues would confirm the deterministic theory. In contrast, I maintain that (...) these findings do not undermine the role of willpower and freedom while reinforcing an interactionist view of free will. If virtues affect our neural system, then the predictability of the virtuous behavior follows. The likelihood of our future actions is primarily virtue-dependent; therefore, the acquired naturality of virtuous behavior is a source of predictable behavioral patterns outlining expected actions, which I propose to call Hypotheses of Action. However, the predictability of an action indicates its likeliness and not its certainty or necessity. The neural traces of virtues can be interpreted as major indicators of HAs. It is always possible for the agents to depart from their more likely, virtue-induced actions, but their deviations from the virtuous behavioral pattern are rare, as it is rare for the vicious/non-virtuous person to behave well systematically. This implies a reaffirmation of the notions of veto and consent as they provide a universal practical power affecting the subject’s use of moral virtues. (shrink)
