肇論新疏 2.160

2.160

二俱有過也。此躡前為難，謂不取順於無知，應合聖心冥暗，如人夜行不辨黑白；有取與知相順，焉有知而不取？以難前云「未嘗取所知」，又云「智非無如」。

Both entail faults. This follows upon the preceding to raise an objection, meaning that if not grasping conforms with non-knowing, it would mean that the sage mind is obscure and dark, like a person traveling at night unable to distinguish black and white; if having grasping conforms with knowing, how could there be knowing without grasping? This objects to the earlier statements, "never grasps a known" and "wisdom is not without knowing."
