俱舍論記 30.28

30.28

「有邊等四至皆有失故」者，論主例釋。若問世間有邊等四句，佛亦不記者，以同常等皆有失故。

Regarding 'The four propositions concerning being finite and so forth [are also not declared] because all incur faults': the author of the treatise explains by analogy. If asked about the four propositions concerning whether the world is finite and so forth, the Buddha also did not declare [an answer], because, identical to [the questions on] eternal, etc., all incur faults.
