US-P18.089ab तदप्यस्त्विति चेत् तन् न लोकायतिकसंगतेः ।US-P18.089cd न च धीर्दृशिरस्मीति यद्याभासो न चेतसि ॥
In plain words
"Fine — let that stand too." If that is your move, no: it puts you shoulder to shoulder with the materialist. And the intellect could not think "I am the seer" at all, if no reflection of consciousness fell on the mind.
Close to the Sanskrit
"Let that too be so" — if (you say) that, that will not do, because of concurrence with the Lokāyatika. And the intellect is not "I am the seer," if there is no reflection in the mind.
