[6] The philosopher Zoroaster simplified the pantheon of early Iranian gods[7] into two opposing forces: Ahura Mazda (Illuminating Wisdom) and Angra Mainyu (Destructive Spirit) which were in conflict.
Gnostic ideas influenced many ancient religions[8] which teach that gnosis (variously interpreted as enlightenment, salvation, emancipation or 'oneness with God') may be reached by practising philanthropy to the point of personal poverty, sexual abstinence (as far as possible for hearers, total for initiates) and diligently searching for wisdom by helping others.
[11][12] In Western civilisation, the basic meanings of κακός and ἀγαθός are "bad, cowardly" and "good, brave, capable", and their absolute sense emerges only around 400 BC, with pre-Socratic philosophy, in particular Democritus.
[citation needed] In Confucianism and Taoism, there is no direct analogue to the way good and evil are opposed, although references to demonic influence is common in Chinese folk religion.
In these works, he states that the natural, functional, "non-good" has been socially transformed into the religious concept of evil by the "slave mentality" of the masses, who resent their "masters", the strong.

Christian Science believes that evil arises from a misunderstanding of the goodness of nature, which is understood as being inherently perfect if viewed from the correct (spiritual) perspective.
The term is drawn from the phrase "the imagination of the heart of man [is] evil" (יֵצֶר לֵב הָאָדָם רַע, yetzer lev-ha-adam ra), which occurs twice at the beginning of the Torah.
Śīla in Buddhism is one of three sections of the Noble Eightfold Path, and is a code of conduct that embraces a commitment to harmony and self-restraint with the principal motivation being nonviolence, or freedom from causing harm.
[42] In adherence to the core principle of spiritual evolution, the Sikh idea of evil changes depending on one's position on the path to liberation.
It has long been thought that this question can best be answered by examining what it is that necessarily makes a thing valuable, or in what the source of value consists.
The good is the harmony of a just political community, love, friendship, the ordered human soul of virtues, and the right relation to the Divine and to Nature.
However, the ancient philosopher Epicurus used the word 'pleasure' in a more general sense that encompassed a range of states from bliss to contentment to relief.
Modern economics thus reflects very ancient philosophy, but a calculation or quantitative or other process based on cardinality and statistics replaces the simple ordering of values.
In the classical political economy of Adam Smith and David Ricardo, and in its critique by Karl Marx, human labour is seen as the ultimate source of all new economic value.
It contrasts with marginal utility theory, which argues that the value of labour depends on subjective preferences by consumers, which may however also be objectively studied.
In non-market societies, labour may be valued primarily in terms of skill, time, and output, as well as moral or social criteria and legal obligations.
The price of labour may then be set by supply and demand, by strike action or legislation, or by legal or professional entry-requirements into occupations.

Rather, what is of intrinsic good is the flourishing of all sentient life, extending to those animals that have some level of similar sentience, such as Great Ape personhood.
[citation needed] Under materialism or even embodiment values, or in any system that recognizes the validity of ecology as a scientific study of limits and potentials, an ecosystem is a fundamental good.
Many have come to the conclusion that without assuming ecosystem continuation as a universal good, with attendant virtues like biodiversity and ecological wisdom it is impossible to justify such operational requirements as sustainability of human activity on Earth.
In many other moral systems, also, remaining on Earth in a state that lacks honor or power over self is less desirable—consider seppuku in bushido, kamikazes or the role of suicide attacks in Jihadi rhetoric.
Ones that relied only on local referents one could verify for oneself, creating more certainty and therefore less investment in protection, hedging and insuring against consequences of loss of the value.
Creativity and innovation and invention are sometimes upheld as fundamentally good especially in Western industrial society—all imply newness, and even opportunity to profit from novelty.
