“All philosophies are mental fabrications. There has never been a single doctrine by which one could enter the true essence of things.”

Nagarjuna, the 2nd-century Buddhist philosopher and founder of the Madhyamaka (Middle Way) school, taught that all philosophical positions are mental constructions. His philosophy of sunyata (emptiness) argues that concepts cannot capture reality's true nature, making this quote representative of his radical skepticism about doctrinal claims to absolute truth.
