成唯識論述記 7.51

7.51

The Commentary states: What does not deeply infer is investigation; what deeply infers is evaluation. The Prakaraṇāryavācā, the Pañcaskandhaka, and so forth all speak of 'the object of mental speech', while fascicle 5 of the Great Treatise speaks of 'objects such as name-bodies (nāmakāya)'. Furthermore, when it is said that not deeply inferring is called volition and deeply inferring is called wisdom, this has two meanings: First, volition does not infer at all, which is termed 'not deeply inferring'—not that it infers subtly—because its meaning is defined as the opposite of wisdom; as the Abhidharma-samuccaya states: 'because it does not infer.' Second, it is said: although volition is not like wisdom in having deep inference, it also has shallow inference; thus in the previous fifth fascicle, in proving that the seventh consciousness lacks investigation and evaluation, it spoke of shallow and deep inference. The Abhidharma-samuccaya's 'does not infer' means that it does not deeply infer. However, when the Abhidharma-samuccaya correlates them in this order, it reverses the sequence, but it is not contradictory to this.
