Critical thinking eludes the modern mind, leading to ethical atrocities.
The problem is that many of us seem to have lost the ability to think for ourselves. We have neglected to make a habit of introspection, rational evaluation, and reasoning hypothetically. Instead of asking ourselves what would be right in any given situation, we accept whatever is lawful. Instead of putting aside self-interest and choosing to do what is right, we reject change because it is inconvenient and might force us to accept responsibility. Instead of employing common sense and fairness, we bow to political correctness and the fear of appearing discriminatory. But in avoiding the discrimination defined by our morally relative and politically-correct world, we fail to discriminate between right and wrong. We fail to exercise our consciences.
