Can they not lie?
It is said people with Asperger Syndrome can not lie. This is true for some but not all; there are also people with Asperger who are pathological liars, either by themselves or out of a desperate attempt to "fit in" in a world where lying is standard behaviour. Also, it is not so much an inability as a virtue; it is the being attached to truth. The inborn full and unconditional dedication to truth, which is the basis for all true science, for scientific curiosity and for justice and law.
It is nowhere more clear than in the person with Asperger who can not lie, that ethical values come from within and are not learnt from educators or influenced by social environment.
