"Pollitical science" is not a science For something to be a science it must follow the scientific method. In particular it must be falsifiable. Political science does not follow the scientific method and is not falsifiable because it is not practical or moral to create political experiments. To create an experiment it is necessary that all factors other than those you want to study be eliminated. This is impossible in the domain of human interaction, where you cannot arrange people into political units as you like, eliminating the effects of culture; therefore there is no science in politics. So it's all a matter of what seems most reasonable. There are no experts in politics; no testability means no way to determine validity, except for reasoning through what seems to make the most sense from one's own point of view. We see the effects of this untestability in the multiplicity of opposing political theses. Were political science a science, fundamental opposition of that nature could not arise; one view would be demonstrably valid, and one would be demonstrably false. The explanation is that there is no way to demonstrate falsehood, and therefore no way to distinguish, except through each individual's unaugmented, natural power of reason.
