Why is the conditional marker "бы" omitted from the construction "Я должен был предвидеть, что ..."?

Question

>Я **должен был предвидеть**, что ...Given the counterfactual conditional aspect of this phrasing, I'd expected to see the conditional marker "бы". I wonder why you can drop "бы" in this particular instance, even though we're clearly talking about something that didn't happen in the past.I assume the literal translation is something like: "I **had to be foreseeing / expecting** that ...". Incidentally, you'd use the conditional tense "j'aurais dû ..." in French to describe the same idea. Is there another phrasing like this that conveys a conditional meaning without using "бы"?

Answer 1

Ah! I suspect that the confusion comes from the English, "I should have foreseen," which sounds counterfactual, to use your wrod, but isn't. Surely what is meant here is something like, "I ought to have.." It was reasonable to foresee.

I understand why you would be confused by this, but there's really nothing countefactual. here.
