答曰：然無是無當者，夫無當則物無不當，無是則物無不是。物無不是，故是而無是；物無不當，故當而無當。

Answer: Indeed, as for being without assertion and without match: because it is without match, no thing does not match; because it is without assertion, no thing is not asserted. Because no thing is not asserted, it is asserted yet without assertion; because no thing does not match, it matches yet without match.
