What does "ever" in the following sentence mean?
Ever tactful, Boswell immediately brought up the subject of the afterlife, asking if there might not be a future state. Source
So Hume is about to die and this guy Boswell starts to talk to him about afterlife. And, we know that Hume was one of the biggest skeptics regarding religion. So the topic in the time is not ever (=at all?) tactful (=polite/sensitive/timely?). Is this what "ever tactful" means?
