[Example of a critique on 'UPB']
'UPB' denies the evolutionairy principle of The Universe :
Evolution in its core principle means change(daoism) (also called 'progress')
Behaviour is based upon the circumstances within an evolutionairy process.
So out of 'bad things' may come 'better things' by evolving from one to another.
Morality itself resides first of all in the Realm of Ideas.
The Ideas in the Mind thereby effects the behaviour of The Maintainer of the Ideas.
Universally Preferable Behaviour gives the impression that behaviour can be :
Universal...
That it is so to speak : Applicable or common to all purposes, conditions, or situations... by logical reasoning or deduction...
In Nature (for emperical evidence) we see that survival overrides Ethics;
Most species survive by swift action even while those animals have no reasoning or logic
The behaviour of those animals adapts from generation to generation.
Preferable behaviour for those animals is heavely dependent on different and even unkown situations and circumstances without any reasoning.
This is an example why it is hard to believe that there could be such thing as
Universal Preferable Behaviour : competition requires innovation also in behaviour
Evolution requires perpetual adaption.
Universal behaviour is therefor not preferable
[An other example]
'Logical Ethics' require all people to reason to the same conclusion :
In the same situation and under the same circumstances 'Logical' Ethics/UPB demands people to render the same ethical conclusion otherwise one or the another is un-ethical; there could be war.
It requires reasoning and logical skills at an equivalent level for all 'logical morals'
If someone is not able to reason out 'the preferable' e.g. because of the complexity of the situation the universal preferable ethics & behaviour paradigmas are flawed.
This is an other example why its difficult to uphold 'Logical' Morality
