Normative ethics is the study of ethical behaviour and is the branch of philosophical ethics that investigates questions regarding how one ought to act, in a moral sense.
Pacifism is the opposition or resistance to war, militarism or violence. The word pacifism was coined by the French peace campaigner Émile Arnaud and adopted by other peace activists at the tenth Universal Peace Congress in Glasgow in 1901. A related term is ahimsa, which is a core philosophy in Indian religions such as Hinduism, Buddhism, and Jainism. While modern connotations are recent, having been explicated since the 19th century, ancient references abound.
The just war theory is a doctrine, also referred to as a tradition, of military ethics that aims to ensure that a war is morally justifiable through a series of criteria, all of which must be met for a war to be considered just. It has been studied by military leaders, theologians, ethicists and policymakers. The criteria are split into two groups: jus ad bellum and jus in bello. The first group of criteria concerns the morality of going to war, and the second group of criteria concerns the moral conduct within war. There have been calls for the inclusion of a third category of just war theory dealing with the morality of post-war settlement and reconstruction. The just war theory postulates the belief that war, while it is terrible but less so with the right conduct, is not always the worst option. The just war theory presents a justifiable means of war with justice being an objective of armed conflict. Important responsibilities, undesirable outcomes, or preventable atrocities may justify war.
Nonviolence is the personal practice of not causing harm to others under any condition. It may come from the belief that hurting people, animals and/or the environment is unnecessary to achieve an outcome and it may refer to a general philosophy of abstention from violence. It may be based on moral, religious or spiritual principles, or the reasons for it may be strategic or pragmatic. Failure to distinguish between the two types of nonviolent approaches can lead to distortion in the concept's meaning and effectiveness, which can subsequently result in confusion among the audience. Although both principled and pragmatic nonviolent approaches preach for nonviolence, they may have distinct motives, goals, philosophies, and techniques. However, rather than debating the best practice between the two approaches, both can indicate alternative paths for those who do not want to use violence.
Virtue ethics is a philosophical approach that treats virtue and character as the primary subjects of ethics, in contrast to other ethical systems that put consequences of voluntary acts, principles or rules of conduct, or obedience to divine authority in the primary role.

Pragmatic ethics is a theory of normative philosophical ethics and meta-ethics. Ethical pragmatists such as John Dewey believe that some societies have progressed morally in much the way they have attained progress in science. Scientists can pursue inquiry into the truth of a hypothesis and accept the hypothesis, in the sense that they act as though the hypothesis were true; nonetheless, they think that future generations can advance science, and thus future generations can refine or replace their accepted hypotheses. Similarly, ethical pragmatists think that norms, principles, and moral criteria are likely to be improved as a result of inquiry.
