Nonkilling, popularised as a concept in the 2002 book Nonkilling Global Political Science, by Glenn D. Paige, refers to the absence of killing, threats to kill, and conditions conducive to killing in human society. Even though the use of the term in academia refers mostly to the killing of human beings, it is sometimes extended to include the killing of animals and other forms of life. This is also the case for the traditional use of the term "nonkilling" (or "non-killing") as part of Buddhist ethics, as expressed in the first precept of the Pancasila, and in similar terms throughout world spiritual traditions (see Nonkilling studies). Significantly, "nonkilling" was used in the "Charter for a World without Violence" approved by the 8th World Summit of Nobel Peace Laureates. Origins The origin of the concept of non-killing can be traced back to ancient Indian philosophy. The concept arises from the broader concept of nonviolence or ahimsa, which is one of the cardinal virtues and an important tenet of Jainism, Hinduism and Buddhism. It is a multidimensional concept, inspired by the premise that all living beings have the spark of the divine spiritual energy; therefore, to hurt another being is to hurt oneself. It has also been related to the notion that any violence has karmic consequences. While ancient scholars of Hinduism pioneered and over time perfected the principles of ahimsa, the concept reached an extraordinary status in the ethical philosophy of Jainism. Historically, several early Indian and Greek philosophers advocated for and preached ahimsa and non-killing. Parsvanatha, the twenty-third tirthankara of Jainism, was one of the earliest person to preach the concept of ahimsa and non-killing around the 8th century BCE. Mahavira, the twenty-fourth and last tirthankara, then further strengthened the idea in the 6th century BCE. The earliest Greek philosophers who advocated for ahimsa and non-killing is Pythagoras. The Indian philosopher Valluvar has written exclusive chapters on ahimsa and non-killing in his work of the Tirukkural. Terms In analysis of its causes, nonkilling encompasses the concepts of peace (absence of war and conditions conducive to war), nonviolence (psychological, physical, and structural), and ahimsa (noninjury in thought, word and deed). Not excluding any of the latter, nonkilling provides a distinct approach characterized by the measurability of its goals and the open-ended nature of its realization. While the usage of terms such as "nonviolence" and "peace" often follow the classical form of
