Abstract

The purpose of this paper is to propose a set of 11 moral rules that are based on a combination of Kant´s categorical imperative, Mill´s Greatest Happiness and Mill´s Principle of Harm. In short the 11 rules of deontoutilitarianism are: 1) Human Beings have the duty of a) to preserve themselves and b) not attempt to destroy the lives of other human beings 2) Rule 1b does not apply if the human being starts an attack against other innocent beings 3) Rule 1a does not apply under extreme physical suffering 4) In exceptional circumstances, where there is conflict between 1a and 1b, it is possible to violate 1a or 1b. 5) Human beings should have plain reproductive freedom 6) Human beings should not discriminate against other human beings. 7) Human beings should never be cruel against other forms of life in the universe 8) Human beings should always protect life in the universe and never threaten other forms of life, except under certain conditions to be described 9) Human beings should not use other living beings as a food source, unless under certain conditions to be described 10) Research involving animals should always respect the 3R’s (Replace, Reduce, Refine) 11) Every human being has the right to know the truth about subjects affecting their personal lives, except when knowing the truth leads to a direct violation of rule 1. Next I apply these rules to examine the morality or immorality of behaviours such as suicide, euthanasia, animal welfare, stem cell research, selection of embryos, reproduction, population policies, immortality, enhancement, war and peace, lying and telling the truth.
