clash of Wahhabism with the theology and Logic

The Wahhabi's confrontation with intellectual sciences is obvious. They oppose with theology and Logic because they are rational sciences. Although it seems that Wahhabis oppose with theology and Logic, they use from these sciences somehow, because these sciences are rational. The Wahhabists' claim is that these sciences are against the method of the Holy Prophet (PBH) and we have consensus that these sciences must be banned. But the findings of this research show that the Wahabis instead of studying logical and theological books, have mostly relied on quotations from others and issued fatwas based on them.
