이위공문대는 당 태종(唐太宗) 이세민(李世民)과 명장인 위국공(衛國公) 이정(李靖)이 병법과 군사 문제 전반에 대하여 문답한 내용을 정리한 병서(兵書)이다. 내용을 보면, 태종은 중원의 태공망 이래 많은 명장과 명인들의 병서를 해부하여 지정지미(至精至微)에 이르기까지 날카롭게 질문을 하고 있으며, 또 대답한 이정은 중원의 많은 전략가 병가들의 사적을 종횡무진으로 파헤쳐 가며 아낌없는 비판을 가하는 지혜로써 대답하고 있다. 까닭에 후세의 병법학자들은, 태종은 한 나라의 황제로서 슬기에 찬 질문을 했고, 또 이정은 그가 무인에 지나지 않지만, 천장만구(千章萬句)의 병서를 종횡무진으로 통달하여 질문에 추호도 어긋남이 없는 대답을 했다 하여, 명문명답의 진귀서라 칭송을 한다.
