I'm looking for a single word that means "almost certainly" but leaves room for 'technical' or 'philosophical' doubt. That is, something like 99.99999...% certain. Or "close enough to certain that we don't need to get hung up on it".
- probably doesn't work because it just means over 50% – way too low.
- indubitably doesn't work because it literally means "undoubtable", i.e. its definition explicitly excludes the possibility of any doubt.
- definitely, certainly, doubtless – strictly speaking, these do not allow for any doubt either (even though they are often used in casual speech for things that aren't truly certain). I want a word that, when used precisely and literally according to its dictionary definition, perhaps in a philosophical/technical/engineering context, actually means "certain, except for the usual 0.00000...1% doubt".
The word should acknowledge a shade of doubt without getting stuck on it, if that makes sense. I don't know if such a word exists, but it seems odd to me if it doesn't, as it seems like it would be very useful in epistemological and engineering discussions.
I guess "beyond reasonable doubt" is a common phrase that means roughly what I want, but I'm wondering if there is a word that (a) is a single word or simple compound, and (b) is used in more of a philosophical/technical/engineering/critical thinking context than a legal one.
