郎尼根以「認知者主體及其運作」來作為其形上學方法的出發點，再以「九重指引」穿梭於「三大程序」之間來作為誘導。其方法論的「三大程序」是為「體認程序」、「破立程序」、與「運籌程序」；而其中的「九重指引」涵括著：1.「心智體認」、2.「知識體認」、3.「校正」、4.「整合」、5.「古典法」、6.「統計法」、7.「生發法」、8.「辯證法」、9.「詮釋法」。郎尼根藉著此等程序與指引的誘導，企圖點化「存有視域」的表裏精粗和全體大用。

Lonergan's method in metaphysics may be summarized as an integral heuristic structure containing 9 directives embedded within 3 main procedures. With Appropriation, Reversal－Development, and Operation as the required procedures, there extends 9 directives which may be labelled as 1.Gnoseological Appropriation, 2.Epistemological Appropriation, 3.Reorientation, 4.Integration, 5.Classical Method, 6.Statistical Method, 7.Genetic Method, 8.Dialectic, and 9.Methodic Hermeneutics. Lonergan aspires that such directives may lead us squarely to the aim of attaining a healthy explicit metaphysics as we hope for.
