OBJECTION: "Logic, uniformity of nature, causation, a mind-independent reality, reliability of sense perception, etc are merely presuppositions of my worldview. They are properly basic and do not need to be justified. We both presuppose them so why do you need to add an extra entity (i.e. God)?"

This kind of objection is encountered rather frequently and is used by unbelievers who have been faced with the insurmountable difficulty of answering the presuppositionalist's questions about these thing...
