Ethics concerns the kind of relation one has to oneself. The essential condition for the practice of ethics is freedom, the ability to choose one action, not another. Foucault makes a distinction between moral codes (which are simply collections of rules and precepts) and ethics. He suggests there are four aspects to how the individual constitutes him/herself as the moral subject of his or her own actions. The first aspect relates to the part of the individual which acts as the focus of moral conduct. The second aspect concerns what makes an individual recognize their moral obligations. The third aspect relates to the means by which individuals transform and work on themselves. The fourth aspect concerns what sort of person an individual might want to be.
