Most
philosophers suggest only
rational beings, who can
reason and form self-interested judgments, are capable of being moral agents. Some suggest those with limited rationality (for example, people who are mildly
mentally disabled or infants
Determinists argue all of our actions are the product of antecedent causes, and some believe this is
incompatible with
free will and thus claim that we have no real control over our actions.
Immanuel Kant argued that whether or not our
real self, the
noumenal self, can choose, we have no choice but to believe that we choose freely when we make a choice. This does not mean that we can
control the effects of our actions. Some Indeterminists would argue we have no free will either. If, with respect to human behavior, a so-called 'cause' results in an indeterminate number of possible, so-called 'effects', that does not mean the person had the free-thinking independent will to choose that 'effect'. More likely, it was the indeterminate consequence of his chance genetics, chance experiences and chance circumstances relevant at the time of the 'cause'. In Kant's philosophy, this calls for an act of faith, the faith free agent is based on something
a priori, yet to be known, or immaterial. Otherwise, without free agent's
a priori fundamental source, socially essential concepts created from human mind, such as justice, would be undermined (responsibility implies freedom of choice) and, in short, civilization and human values would crumble. It is useful to compare the idea of moral agency with the
legal doctrine of
mens rea, which means guilty mind, and states that a person is legally responsible for what he does as long as he
should know what he is doing, and his choices are deliberate. Some theorists discard any attempts to evaluate mental states and, instead, adopt the doctrine of
strict liability, whereby one is liable under the law without regard to capacity, and that the only thing is to determine the degree of
punishment, if any. Moral determinists would most likely adopt a similar point of view. Psychologist
Albert Bandura has observed that moral agents engage in selective
moral disengagement in regards to their own inhumane conduct. ==Distinction between moral agents and moral patients==
