Reason grounds Western morality, with its respect for the individual and her freedom at its center. The force of this system has created a moral industry in the West - with think tanks, politicians and journalists broadcasting its goodness - but the continued use of torture undermines it all, argues Kishore Mahbubani.

One of the greatest joys of my life was studying Western philosophy, absorbing the wisdom of great Western thinkers from Socrates to Wittgenstein. The dedication of all those great thinkers, over thousands of years, to the power of logical reasoning was truly inspiring. Hence, for me, the power of the West was always associated with this commitment to using reason to understand and improve the world.

Western logic was always irrefutable. Plain logic would create irrefutable statements. Hence if the premise was “all dogs are animals”, the consequence of the claim “Fido is a dog” was the irrefutable statement that “Fido is an animal”. A similar rigour applied to moral reasoning. Hence, if a human being called X said “Human beings should not torture other human beings”, the irrefutable conclusion was that X was obliged to also say “I should not torture human beings”. The rigour of this logic is absolute. No exceptions are possible. Anyone who made the first claim and denied the second claim would be justifiably accused of hypocrisy.
