Aristotle asserts that even though people with a bad character may be ignorant and even seem unable to choose the right things,
this condition stems from decisions which were originally voluntary, the same as poor health can develop from past choices; and “while no one blames those who are ill-formed by nature, people do censure those who are that way through lack of exercise and neglect”.
The vices then, are voluntary just as the virtues are. He states that people would have to be unconscious not to realize the importance of allowing themselves to live badly, and he dismisses any idea that different people have different innate visions of what is good.
