The Good is the highest aim in a human life. (e.g. in Plato). It
does not necessarily refer to God or to the Gods, but to what
humans ought to do. The Ancient Greeks recognized that The Good
was transcendental, had to be transcendental - had to be
something outside and beyond humans to which each could aspire
(and which they might fail to attain). The Good is highest, but
it is hard to understand, hard to think about - and most people
usually focus on three component transcendental goods of Truth,
Beauty and Virtue (moral good). However, there is a problem in
splitting up the Good - which is that people begin to evaluate
the world using separate modalities of thought. Truth becomes
the province of - firstly - philosophy, then later science.
Beauty becomes the province of Art. And Virtue? Virtue becomes
religion - the whole thing! - or later Virtue may become a
secular ideology. And indeed morality can become the whole of
religion - such that people cannot see that religion has
anything to do with either Truth
