 The judgment that a person is morally responsible for her behavior involves—at least to a first approximation—attributing certain powers and capacities to that person, and viewing her behavior as arising (in the right way) from the fact that the person has, and has exercised, these powers and capacities. Whatever the correct account of the powers and capacities at issue (and canvassing different accounts is the task of this entry), their possession qualifies an agent as morally responsible in a general sense: that is, as one who may be morally responsible for particular exercises of agency. Normal adult human beings may possess the powers and capacities in question, and non-human animals, very young children, and those suffering from severe developmental disabilities or dementia (to give a few examples) are generally taken to lack them.
