Good

{{Further|Form of the good|Origins of morality|Morality}}

Every language has a word expressing ''good'' in the sense of "having the right or desirable quality" ([[Arete (moral virtue)|ἀρετή]]) and ''bad'' in the sense "undesirable". A sense of [[morality|moral judgment]] and a distinction "right and wrong, good and bad" are [[cultural universals]].<ref>[[Donald Brown (anthropologist)|Donald Brown]] (1991) ''Human Universals''.

=== Plato and Aristotle ===

Although the history of the origin of the use of the concept and meaning of "good" are diverse, the notable discussions of Plato and Aristotle on this subject have been of significant historical effect. The first references that are seen in Plato's ''The Republic'' to the [[Form of the Good]] are within the conversation between [[Glaucon]] and [[Socrates]] (454c–d). When trying to answer such difficult questions pertaining to the definition of [[justice]], Plato identifies that we should not "introduce every form of difference and sameness in nature" instead we must focus on "the one form of sameness and difference that was relevant to the particular ways of life themselves”, which is the form of the Good. This form is the basis for understanding all other forms, it is what allows us to understand everything else. Through the conversation between Socrates and Glaucon (508a–c) Plato analogizes the form of the Good with the sun as it is what allows us to see things. Here, Plato describes how the sun allows for sight. But he makes a very important distinction, "sun is not sight", but it is "the cause of sight itself". As the sun is in the visible realm, the form of Good is in the [[Intelligibility (philosophy)|intelligible]] realm. It is "what gives truth to the things known and the power to know to the knower". It is not only the "cause of knowledge and truth, it is also an object of knowledge".
 
Plato identifies how the form of the Good allows for the cognizance to understand such difficult concepts as justice. He identifies knowledge and truth as important, but through Socrates (508d–e) says, "good is yet more prized". He then proceeds to explain that "although the good is not being" it is "superior to it in rank and power", it is what "provides for knowledge and truth" (508e).<ref name=Reeve>{{cite book|last=Plato|translator=C.D.C.

In contrast to Plato, [[Aristotle]] discusses the Forms of Good in critical terms several times in both of his major surviving ethical works, the ''[[Eudemian Ethics|Eudemian]]'' and ''[[Nicomachean Ethics]]''. Aristotle argues that Plato's Form of the Good does not apply to the physical world, for Plato does not assign "goodness" to anything in the existing world. Because Plato's Form of the Good does not explain events in the physical world, humans have no reason to believe that the Form of the Good exists and the Form of the Good thereby, is irrelevant to human ethics.<ref name=plat>{{cite book|last=Fine|first=Gail|title=Plato on Knowledge and Forms|url=https://archive.org/details/platoonknowledge00fine_595|url-access=limited|date=2003|publisher=Oxford University Press|location=New York|isbn=0-19-924559-2|pages=[https://archive.org/details/platoonknowledge00fine_595/page/n361 350]}}</ref>

Plato and Aristotle were not the first contributors in ancient Greece to the study of the "good" and discussion preceding them can be found among the pre-Socratic philosophers. 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]].<ref>[[Charles H. Kahn]], ''Democritus and the Origins of Moral Psychology'', The American Journal of Philology (1985)</ref> Morality in this absolute sense solidifies in the dialogues of [[Plato]], together with the emergence of [[monotheistic]] thought (notably in ''[[Euthyphro]]'', which ponders the concept of piety ([[:wikt:ὅσιος|τὸ ὅσιον]]) as a moral absolute). The idea is further developed in [[Late Antiquity]] by [[Neoplatonists]], [[Gnostics]], and [[Church Fathers]].

=== Ancient western religions ===

{{Further|Zoroastrianism|Gnosticism}}
Aside from ancient Greek studies of the "good", more than twenty-five hundred years ago in the eastern part of ancient [[Greater Iran|Persia]] a religious philosopher called [[Zoroaster]] simplified the [[Pantheon (gods)|pantheon]] of early Iranian deities <ref name="Boyce_1979_6-12">{{harvnb|Boyce|1979|pp=6–12}}</ref> into [[Dualistic cosmology|two opposing forces]]: [[Ahura Mazda]] ([[Light (theology)|Illuminating]] [[Wisdom]]) and [[Angra Mainyu]] ([[devil|Destructive Spirit]]) that were in conflict.

For the western world, this idea developed into a religion that spawned many [[sect]]s, some of which embraced an extreme [[Dualistic cosmology|dualistic]] belief that the [[nature|material world]] should be shunned and the [[Sacred|spiritual world]] should be embraced. Gnostic ideas influenced many [[Ancient history|ancient]] religions,<ref>{{cite book |title=The Penguin Dictionary of Religion| year=1997|publisher=Penguin Books UK|author=John Hinnel}}</ref> which teach that ''[[gnosis]]'' (variously interpreted as [[Enlightenment in Buddhism|enlightenment]], [[salvation]], [[moksha|liberation]], or "oneness with God") may be reached by practising philanthropy to the point of personal poverty, [[sexual abstinence]] (as far as possible for ''[[wikt:disciple#Noun|hearers]]'' and totally for ''[[Initiation|initiates]]''), and diligently searching for [[wisdom]] by helping others.<ref name=gph>{{cite book |title=Gnostic Philosophy: From Ancient Persia to Modern Times|first=Tobias |last=Churton|publisher=Inner Traditions – Bear & Company |date=2005|isbn=978-159477-035-7}}</ref>

This development from the relative or habitual to the absolute is evident in the terms ''ethics'' and ''[[morality]]'' as well, both being derived from terms for "regional custom", Greek ἦθος and Latin ''mores'', respectively (see also ''[[:wikt:siðr|siðr]]'').

=== Medieval period in western cultures ===
{{Further|Christian philosophy}}
[[File:Saint Joseph's Catholic Church (Central City, Kentucky) - stained glass, St. Thomas Aquinas, detail.jpg|thumb|upright|A stained glass window of Thomas Aquinas in St. Joseph's Catholic Church ([[Central City, Kentucky]])]]
Medieval [[Christian philosophy]] was founded on the work of Bishop [[Augustine of Hippo]] and theologian [[Thomas Aquinas]], who understood evil in terms of [[Biblical infallibility]] and [[Biblical inerrancy]], as well as the influences of Plato and Aristotle, in their appreciation of the concept of the [[Summum bonum]]. Silent contemplation was the route to appreciation of the Idea of the Good.<ref>A. Kojeve, ''Introduction to the Reading of Hegel'' (1980) p. 108</ref>

Many medieval Christian theologians both broadened and narrowed the basic concept of ''Good and Evil'' until it came to have several, sometimes complex definitions such as:<ref>{{cite book |title=Good and Evil: Interpreting a Human Condition|author=Farley, E|publisher=Fortress Press / Vanderbilt University|year=1990|isbn=978-0800624477}}</ref> 
* a personal preference or subjective judgment regarding any issue that might earn [[praise]] or [[punishment]] from the [[Theocracy|religious authorities]]
* religious obligation arising from [[Divine law]] leading to [[saint|sainthood]] or [[damnation]] 
* a generally accepted [[Norm (social)|cultural standard]] of behaviour that might enhance group [[Human evolution (origins of society and culture)|survival]] or wealth
* [[natural law]] or behaviour that induces strong emotional reaction
* [[State (polity)|statute law]] imposing a legal [[duty]]

=== Modern concepts ===
==== Kant ====
{{main|Kant|Critique of Practical Reason}}
A significant enlightenment context for studying the "good" has been its significance in the study of "[[Transcendentals|the good, the true, and the beautiful]]" as found in [[Immanuel Kant]] and other Enlightenment philosophers and religious thinkers. These discussions were undertaken by Kant, particularly in the context of his ''[[Critique of Practical Reason]]''.

==== Rawls ====
[[John Rawls]]'s book ''[[A Theory of Justice]]'' prioritized social arrangements and goods, based on their contribution to [[justice]]. Rawls defined justice as ''fairness'', especially in distributing social goods, defined fairness in terms of procedures, and attempted to prove that just institutions and lives are good, if every rational individual's goods are considered fairly. Rawls's crucial invention was the [[original position]], a procedure in which one tries to make objective moral decisions by refusing to let personal facts about oneself enter one's moral calculations.
