Shiavault - a Vault of Shia Islamic Books Eternity of Moral Values Three Ethical Theories Bertrand Russell is one of the thinkers who arrived at the same conclusion through his philosophy of logical analysis.
In his book, A History of Western Philosophy, while examining Plato's conception of justice and Trasymachus's famous objection against it, that justice is nothing but the interests of the powerful, Russell is of the view that this is the basic problem of politics and ethics: is there any criterion iii ethics to distinguish between good and bad except that which is meant by those who use these terms? If there is no such criterion then most of Trasymachus's conclusions will inescapable.
But how can one say that such a criterion exists? Elsewhere Russell says that the difference between Plato and Trasymachus is very important. Plato thinks that he can prove that his idea of republic is good. A democrat who accepts the objectivity of ethics may think that he can prove the Republic to be immoral; but anyone who agrees with Trasymachus will say: There is no question of proving or disproving; the only question is whether you like or not.
If you do, it is good for you; if you do not it is bad for you. It is like matters of taste; one may like a certain kind of food and say that this food is good and others may like another kind and say that, that food is good. There is no absolute good to compare other goods with. He further says that if you like it, it is good for you; if you do not, it is bad for you. If some like it and some don't the matter cannot be decided by reason, but only by force.
That which is said that justice belongs to the powerful, that is because when some people like something and others don't, those who have greater power impose their wishes on others by force and that becomes law. The gist of Russell's statements is that the concepts of good and bad indicate the relation between man and the thing in question. If this relation is one of liking it is good and if it is one of dislike then it is bad. If it is neither liked nor disliked, then it neither good nor evil.
We have written that the answer to Russell is that first we have to trace the roots of why man likes something and dislikes something else. Man likes anything that serves the purpose of life even if from a particular aspect.
