因明入正理論疏 1.104

1.104

初二句是宗體，一攝受論宗、二若自辯才。初依自所師宗，對異師敵而立自宗。不爾，便為相符極成。後由自辯才立他宗義，隨自意樂，不顧論宗。唯此二種是正所宗。若遍所許、若二同宗承、若傍義准，非別攝受、非隨自樂，故非真宗，立已成故、非本成故。

The first two phrases concern the essence of the thesis: first, accepting the doctrine of a school; second, according to one's own dialectical skill. The former means that based on the school one adheres to, one establishes one's own thesis against an opponent of a different school. Otherwise, it would become established as agreed upon. The latter means that through one's own dialectical skill, one establishes a doctrine of another school in accordance with one's own intention, without regard to school doctrine. Only these two kinds are genuinely what is taken as the thesis. If it is universally accepted, or accepted by both parties of the same tradition, or an ancillary implication, it is not distinctively accepted nor is it in accordance with one's own intention; therefore, it is not a true thesis, because it is establishing what is already established, or because it is not fundamentally established.
