This question immediately brings to mind the approach known as Prasangika-Madhyamaka, which uses the method of reductio ad absurdum to uproot all views without replacing them with another. Madhyamaka is a school of Indian-Buddhist logic spearheaded by Nagarjuna, but with roots in the earlier texts as well. Reading Nagarjuna and referring to the Atthakavagga of the Sutta Nipata in addition to various other discourses such as the Lokayatika Sutta (SN 12.48) have helped me loosen my grip on metaphysical concepts and speculative views.
