Yes, Epicurus talks about “Speculative Judgement,” (hē theōrētikē doxa), i.e. judgement about conceivable universal characteristics; and the truth-value of this kind of judgement is tested by attestation and contestation via indirect practical consequences. He treats this as belonging to analogical consideration (ho analogismos).
So, as we know, the issue isn’t abstraction as such, but whether the abstraction is (and remains) attested (or not contested) by sensation. The error, if there is one, lies in our “addition of judgement” (to prosdoxazomenon).
