Good and bad
In philosophy, goodness is generally understood in two main kinds: either a thing is good  or it is good . For example, eating properly may be good  (provable) but eating properly may not be a good  (unprovable). This also applies to things that are called bad. The belief that there are such things as good  and bad  has been a main part of Western philosophy since Plato. However, some philosophers have rejected this belief.
