If this fails to impress you, he becomes a statist to force your obedience. A practicing statist is a thug. If you have no rights, then you're fair game for force. A bully is a free lance dictator. If thieves and bullies get governments to do their dirty work, they remain thieves and bullies.
Skepticism is the rejection of reason.
Reason is the actual target of skeptical attacks. Every skeptical argument is aimed squarely at the evidence of the senses and the validity of thinking, i.e., at the essentials of reason itself. The skepticism of the Sophists prepared the way for Plato's supernaturalism. Only when a man has been led to despair of his own grasp of reality can he be sold fairy tales wholesale. The worst mystics understand their dependence on skepticism very well.
