" But these self-appointed teachers lack personal experience, and do not even listen when others speak to them. Relying solely on their own self-assurance, they order their brethren to wait on them like slaves. They glory in this one thing: to have many disciples. Their main objective is to ensure that, when they go about in public, their retinue of followers is no smaller than those of their rivals. They behave like mountebanks rather than teachers. They think nothing of giving orders, however burdensome, but they fail to teach others by their own conduct. Thus they make their purpose obvious to all: they have insinuated themselves into a position of leadership, not for the benefit of their disciples, but to promote their own pleasure. "
