— the (doctrine that the) effect pre-exists (in the cause); — is not tenable; — if (you object); — of what already exists; — what (need); — with an operative cause; — since; — manifestation; — (or) if (you say); — of it; — here; — is produced; — that (manifestation) too; — is it existent (or not)?
(Objection:) The doctrine that the effect pre-exists is untenable — for what need has the already-existent of an operative cause? (Reply-objection:) Or if you say its manifestation is produced here (instead), then is that manifestation itself existent (or not)?
