Let's say that someone believes that philosophy in itself is a bad thing. If I'm correct, the only way to combat this premise is to use philosophy (which is off limits since it's on trial)!
Similarly, (a real example) a Christian writer publishes a book on why theology and theologians have done all they can to ruin Christianity (allegedly muddling up the "simplicity" of Jesus' teachings) and therefore, theology is bad. This is clearly a theological stance and the only way to combat it is with theology...
Am I seeing something that isn't there?
Does anyone know the name of this fallacious argument? It seems to shut the debate down before it even starts. Does anybody have any other examples of this besides theology?
