Ethics and rationality

If we consider that ethics and rationality are what really matters, we must accept that any impediments to independent thinking are of a pernicious nature. Religion, patriotism, and ideology, the major sources of dogma, are made of preconceived concepts and ideas which, if ingrafted into the minds of people, will impose, in the decision-making process, a bias that may counterbalance the urge for ethics and rationality.  It is as simple as that. It is a matter of choice. Incompatible positions cannot coexist in the same mind. If you choose to be ethical and rational, you must understand that if you must discard the adoption of any religious, patriotic, or ideological principles. Any claims to lodging such opposed principles in the same mind is a contradiction
